This new method for PEDV detection was 10 times more sensitive than the conventional reverse transcription-polymerase chain reaction (RT-PCR) assay. To decrease the time required for PEDV detection, PCR-related methods focused on the amplification of viral nucleic acids have been developed, which have been shown to be more efficient, highly sensitive and specific, even at different stages of the disease, when compared to immunological diagnostic methods. The polymerase spiral reaction (PSR) [14] is a novel nucleic acid isothermal amplification method that has the advantages of simplicity, rapidity, accuracy, and low cost when compared to conventional PCR. cache = ./cache/cord-003587-zminzrov.txt txt = ./txt/cord-003587-zminzrov.txt === reduce.pl bib === === reduce.pl bib === === reduce.pl bib === id = cord-003208-lwirkob3 author = Yan, Liping title = Novel protein chip for the detection of antibodies against infectious bronchitis virus date = 2018-09-17 pages = extension = .txt mime = text/plain words = 3973 sentences = 220 flesch = 52 summary = RESULTS: We have developed two indirect microarray methods to detect antibodies against IBV: a chemiluminescent immunoassay test (CIT) and a rapid diagnostic test (RDT).

The proportional morbidity ratio of FIV to FeLV infection was estimated for each administrative region and its geographic distribution pattern was visualized by a choropleth map. The proportional morbidity ratio (PMR) of FIV to FeLV infection was estimated for each administrative region and a choropleth disease map was used to visualize the spatial pattern of PMR. Areas of relative FIV excess identified by the spatial scan statistic were visualized by highlighting the boundaries of the states included in the most likely cluster on a choropleth map of the PMR of FIV to FeLV infection. In this study we have identified geographical patterns in the distribution of the proportional morbidity ratio of FIV to FeLV infection among cats in the 49 administrative regions of the US over the period 2000 to 2011. cache = ./cache/cord-285714-u9kv4113.txt txt = ./txt/cord-285714-u9kv4113.txt === reduce.pl bib === id = cord-279551-py2awuav author = Willi, Barbara title = Clinical and molecular investigation of a canine distemper outbreak and vector-borne infections in a group of rescue dogs imported from Hungary to Switzerland date = 2015-07-16 pages = extension = .txt mime = text/plain words = 6264 sentences = 315 flesch = 53 summary = title: Clinical and molecular investigation of a canine distemper outbreak and vector-borne infections in a group of rescue dogs imported from Hungary to Switzerland In the present study, we describe a distemper outbreak in 15 rescue dogs that were imported from Hungary to Switzerland by an animal welfare organisation.

CONCLUSIONS: These results indicated that the dietary addition of SRB in milk did not have an effect in health, immunity or performance of pre-weaned dairy calves. We hypothesized that the addition of SRB in milk of pre-weaned calves would reduce the presentation and severity of neonatal diarrhea, improving the immune response and consequently the overall calf performance. The addition of prebiotics via SRB into milk starting at 6-7 days of age was assessed for effects on health and performance of pre-weaned organic dairy calves over a 28 days period. The major finding from this study was that the addition of SRB in the milk of newborn calves for 28 days did not enhance performance, health, or immunity during the first month of life, a period characterized for the presentation of digestive diseases. cache = ./cache/cord-337354-ky8mq4y0.txt txt = ./txt/cord-337354-ky8mq4y0.txt === reduce.pl bib === id = cord-336902-iptfle2b author = Harada, Kazuki title = First case of Propionibacterium acnes urinary tract infection in a dog date = 2015-12-21 pages = extension = .txt mime = text/plain words = 1937 sentences = 128 flesch = 47 summary = title: First case of Propionibacterium acnes urinary tract infection in a dog Urinary tract infections are common in dogs and are typically caused by various commensal bacteria.

In the current report, we present the characterisation of ORT and H9N2 isolates obtained from co-infected broilers, with the objective of understanding the aetiology of severe avian pneumonia. Broilers inoculated intraperitoneally with ORT/chicken/Shandong/2011 alone displayed pneumonia and typical airsacculitis, and coinfection of the broilers with ORT and H9N2 virus isolates induced higher mortality than infection with ORT or H9N2 virus alone. The results of this study strongly suggest that co-infection with ORT and H9N2 virus is responsible for the current severe pneumonia with high mortality in broilers of China. However, the birds infected with the ORT isolated in this study had a 50% mortality rate, and a co-infection with the H9N2 virus resulted in 70% death.

During the first 28 days, vaccinated calves shed both the vector strain and the intimin-expressing S. Calves challenged with intimin-deficient mutant bacteria do not develop diarrhea or attaching/ effacing lesions, nor are colonized to the same extent as animals infected with wild type or complemented mutant strains [20] . Fecal samples from all the calves were collected daily from day 0 to day 42 post-inoculation to determine the level of vaccine strain shedding.

The detection limits of PEDV RNA in the both PEDV real-time RT-RPA assays were 300 copies within 20 min at 39 °C, and the detection limits of classical attenuated vaccine strain CV777, Vero-cell-adapted isolate JS2008, and PEDV wild-type strain DX were 10(0.5) TCID(50)/100 μL, 10(1.1) TCID(50)/100 μL, and 10(1.2) TCID(50)/100 μL, respectively. CONCLUSION: This RPA method we developed is simple, time-effective, and safe and provides a reliable technical tool for the differential diagnosis and clinical epidemic surveillance of PEDV classical attenuated vaccine strains and wild-type strains. cache = ./cache/cord-346457-2mq2aije.txt txt = ./txt/cord-346457-2mq2aije.txt === reduce.pl bib === id = cord-347664-8shnkrto author = Kang, JeongWoo title = National post-market surveillance assessment of veterinary medicines in Korea during the past decade date = 2017-05-22 pages = extension = .txt mime = text/plain words = 2758 sentences = 137 flesch = 44 summary = RESULTS: In this study, 1650 drugs for veterinary use were collected per year from each city and province in Korea and analysed for the quantity of active ingredients according to the "national post-market surveillance (NPMS) system" over the past decade.

In this study, although all cases were selected using clinical features and epidemiological information, the histological evaluation consistently showed lesions compatible with viral infection. The application of IHC and ISH-RNA on archived paraffin blocks from cases of neonatal diarrhea with high morbidity and mortality allowed retrospective identification of TGEV infection. During the period when the sows showed gastro-enteric clinical signs, 2-to 4-day-old piglets presented vomiting (75-80%) and diarrhea (90%), and the mortality rate of suckling pigs reached 90%.

summary: The possibility of stratifying and classifying septic dogs was assessed using a proposed animal adapted PIRO (Predisposition, Infection, Response and Organ dysfunction) scoring system. RESULTS: The 72 dogs enrolled in this study were scored for each of the PIRO elements, except for Infection, as all were considered to have the same infection score, and subjected to two sets of SIRS criteria, in order to measure their correlation with the outcome. The main objective of the current study was to assess the prognostic value of the presenting vital signs as well as to evaluate the possibility of stratifying and classifying septic animals according to a proposed PIRO classification system, using parvovirus infection as a natural model for sepsis study [10] . Table 1 gathers all leucocyte counts, a selection of clinical examination parameters (Temperature, Heart Rate and Respiratory Rate), all individual variables of PIRO (P=Predisposition, I=Infection, R = Response, O=Organ Dysfunction), the total PIRO score and both SIRS criteria for survivors and non-survivors dogs. abstract: BACKGROUND: Sepsis is a severe condition associated with high prevalence and mortality rates. Parvovirus enteritis is a predisposing factor for sepsis, as it promotes intestinal bacterial translocation and severe immunosuppression. This makes dogs infected by parvovirus a suitable study population as far as sepsis is concerned. The main objective of the present study was to evaluate the differences between two sets of SIRS (Systemic Inflammatory Response Syndrome) criteria in outcome prediction: SIRS 1991 and SIRS 2001. The possibility of stratifying and classifying septic dogs was assessed using a proposed animal adapted PIRO (Predisposition, Infection, Response and Organ dysfunction) scoring system. RESULTS: The 72 dogs enrolled in this study were scored for each of the PIRO elements, except for Infection, as all were considered to have the same infection score, and subjected to two sets of SIRS criteria, in order to measure their correlation with the outcome. Concerning SIRS criteria, it was found that the proposed alterations on SIRS 2001 (capillary refill time or mucous membrane colour alteration) were significantly associated with the outcome (OR = 4.09, p < 0.05), contrasting with the 1991 SIRS criteria (p = 0.352) that did not correlate with the outcome. No significant statistical association was found between Predisposition (p = 1), Response (p = 0.1135), Organ dysfunction (p = 0.1135), total PIRO score (p = 0.093) and outcome. To explore the possibility of using the SIRS criteria as a fast decision-making tool, a Fast-and-Frugal tree (FFT) was created with a sensitivity of 92% and a specificity of 29%. CONCLUSION: These results suggest that increasing the SIRS criteria specificity may improve their prognostic value and their clinical usefulness.

Since the ribotypes found in dogs are also commonly found in humans, it is possible Fig. 2 Metronidazole susceptibility test of Clostridium difficile D24 strain after 48 h of incubation. Antibiotic resistance patterns and PCR-ribotyping of Clostridium difficile strains isolated from swine and dogs in Italy abstract: BACKGROUND: Clostridium difficile infection (CDI) is recognised as an emerging disease in both humans and some animal species. During the past few years, insights into human CDI epidemiology changed and C. difficile is also considered as an emerging community-acquired pathogen. Certain ribotypes (RT) are possibly associated with zoonotic transmission. The objective of this study was to assess the presence of C. difficile in a population of pets and to characterise the isolates. RESULTS: Faecal samples from a total of 90 diarrhoeic dogs and 24 from exotic animal species (both diarrhoeic and non-diarrhoeic) were analysed. Clostridium difficile was isolated from 6 (6.7%) dogs and one reptile sample (4.2%). Four (66.7%) of the six dog strains were capable of producing toxins. Four known different RTs were detected in dogs (010, 014, 123 and 358) and a new one was found in a faecal sample of an exotic animal. This new RT isolate was negative for all toxin genes tested and belonged to sequence type 347 which has been proposed as a Clade-III member. Importantly, two dog strains showed a stable resistance to metronidazole (initial MIC values: 128 and 48 μg/ml). CONCLUSIONS: The results obtained in this study suggest the implementation of antimicrobial susceptibility surveillance programs to assess the prevalence of metronidazole resistance in dogs; molecular studies to elucidate C. difficile metronidazole resistance mechanisms are warranted. Based on the similarity between the ribotypes observed in dogs and those described in humans, the zoonotic transmission should be further explored. Furthermore, exotic animals have shown to harbor uncommon C. difficile strains which require further genomic studies.

Thai medicinal plants such as Caesalpinia sappan Linn., Garcinia mangostana Linn., Houttuynia cordata, Perilla frutescens, Clinacanthus nutans, Phyllanthus emblica, and Tiliacora triandra are known to have antioxidant and antiviral activities. Therefore, the aim of this study was to determine the antiviral activities of Thai medicinal plant extracts against PRRSV infection in vitro and to measure their phytochemical contents to develop an alternative anti-PRRSV therapy for use in veterinary medicine. In this study, we investigated the antiviral activity of seven Thai medicinal plant extracts against PRRSV by assessing the inhibition of PRRSV infection and replication in MARC-145 cells. abstract: BACKGROUND: Porcine reproductive and respiratory syndrome (PRRS) caused by PRRS virus (PRRSV) results in economic losses in the swine industry globally. Several studies have investigated the use of plant extracts in the prevention and control of PRRS outbreaks. Thai medicinal plants may be useful for treating PRRSV infection in pigs. Therefore, we investigated the in vitro anti-PRRSV and antioxidant properties of seven Thai medicinal plants: Caesalpinia sappan Linn., Garcinia mangostana Linn., Houttuynia cordata, Perilla frutescens, Clinacanthus nutans, Phyllanthus emblica, and Tiliacora triandra. RESULTS: Using antiviral screening, we observed that T. triandra extract strongly inhibited PRRSV infectivity in MARC-145 cells [virus titer 3.5 median tissue culture infective dose (TCID(50))/ml (log10)] at 24 h post-infection, whereas C. sappan extract strongly inhibited PRRSV replication [virus titer 2.5 TCID(50)/ml (log10)] at 72 h post-infection. C. sappan extract had the highest total phenolic content [220.52 mM gallic acid equivalent/g] and lowest half-maximal inhibitory concentration [1.17 mg/ml in 2,2-diphenyl-1-picrylhydrazyl and 2.58 mg/ml in 2,2-azino-bis (3-ethylbenzothiazo-line-6-sulfonic acid) diammonium salt]. CONCLUSION: T. triandra extract could inhibit PRRSV infectivity, whereas C. sappan extract was the most effective in inhibiting PRRSV replication in MARC-145 cells. This study elucidates the antiviral activities of Thai medicinal plant extracts in vivo. The results promise that Thai medicinal plant extracts, particularly T. triandra and C. sappan extracts, can be developed into pharmaceutical drugs for the prevention of PRRS in pigs. url: https://doi.org/10.1186/s12917-020-02320-8 doi: 10.1186/s12917-020-02320-8 id: cord-292033-zkwiag7a author: Balboni, Andrea title: Molecular analysis of carnivore Protoparvovirus detected in white blood cells of naturally infected cats date: 2018-02-05 words: 4806.0 sentences: 219.0 pages: flesch: 48.0 cache: ./cache/cord-292033-zkwiag7a.txt txt: ./txt/cord-292033-zkwiag7a.txt summary: Detection of FPV and CPV variants in apparently healthy cats and their persistence in white blood cells (WBC) and other tissues when neutralising antibodies are simultaneously present, suggest that parvovirus may persist long-term in the tissues of cats post-infection without causing clinical signs.

Furthermore, the ability of FPV and CPV to persist in the peripheral blood mononuclear cells (PBMC) of cats irrespective of the presence of neutralising antibodies [13] [14] [15] [16] [17] and the presence of parvoviral DNA in the bone marrow of healthy cats [18] , suggests that parvovirus may persist long term in the tissues of cats post-infection without causing clinical signs. abstract: BACKGROUND: Cats are susceptible to feline panleukopenia virus (FPV) and canine parvovirus (CPV) variants 2a, 2b and 2c. Detection of FPV and CPV variants in apparently healthy cats and their persistence in white blood cells (WBC) and other tissues when neutralising antibodies are simultaneously present, suggest that parvovirus may persist long-term in the tissues of cats post-infection without causing clinical signs. The aim of this study was to screen a population of 54 cats from Sardinia (Italy) for the presence of both FPV and CPV DNA within buffy coat samples using polymerase chain reaction (PCR). The DNA viral load, genetic diversity, phylogeny and antibody titres against parvoviruses were investigated in the positive cats. RESULTS: Carnivore protoparvovirus 1 DNA was detected in nine cats (16.7%). Viral DNA was reassembled to FPV in four cats and to CPV (CPV-2b and 2c) in four cats; one subject showed an unusually high genetic complexity with mixed infection involving FPV and CPV-2c. Antibodies against parvovirus were detected in all subjects which tested positive to DNA parvoviruses. CONCLUSIONS: The identification of FPV and CPV DNA in the WBC of asymptomatic cats, despite the presence of specific antibodies against parvoviruses, and the high genetic heterogeneity detected in one sample, confirmed the relevant epidemiological role of cats in parvovirus infection. url: https://doi.org/10.1186/s12917-018-1356-9 doi: 10.1186/s12917-018-1356-9 id: cord-294559-u0r7oh9z author: Bian, Hongfen title: A new immunochromatographic assay for on-site detection of porcine epidemic diarrhea virus based on monoclonal antibodies prepared by using cell surface fluorescence immunosorbent assay date: 2019-01-18 words: 5654.0 sentences: 346.0 pages: flesch: 63.0 cache: ./cache/cord-294559-u0r7oh9z.txt txt: ./txt/cord-294559-u0r7oh9z.txt summary: title: A new immunochromatographic assay for on-site detection of porcine epidemic diarrhea virus based on monoclonal antibodies prepared by using cell surface fluorescence immunosorbent assay For rapid detection of PEDV, a new immunochromatographic assay (ICA) based on monoclonal antibodies (mAbs) was developed in this study. To compare its accuracy to other traditional detection methods, 27 swine stool samples from south of China were investigated with the new developed ICA, commercial strip and RT-PCR.

They were capture and detection mAb, the size of gold nanoparticles, the type of sample pad, the type of conjugate pad, the type of Nitrocellulose membrane, the type of absorbent pad, the amount of tween-20 addition and the spray volume of AuNPs-mAb. The optimization methods are shown in the supplemental materials. abstract: BACKGROUND: Porcine epidemic diarrhea virus (PEDV) is a highly effective pathogen that can cause death of new-born piglet, resulting in big economical loss in pig farming industry. For rapid detection of PEDV, a new immunochromatographic assay (ICA) based on monoclonal antibodies (mAbs) was developed in this study. RESULTS: The mAbs were prepared by using PEDV positive hybridoma cells that were selected by using cell surface fluorescence immunosorbent assay (CSFIA). Fourteen mAbs against PEDV strain isolated from south of China were prepared. The optimal mAb 4A11 was coated on NC membrane as the capturing reagent and the mAb A11H7 was coupled to gold nanoparticles (AuNPs) as detection reagent for the new ICA. The new ICA was used to measure PEDV in phosphate buffer containing tween-20. Results indicated that the limit of detection (LOD) of the new ICA was 0.47 μg/mL (5.9 × 10(3) TCID(50)/mL) and the liner detection range of the ICA was 0.625–10 μg/mL (7.8 × 10(3)–10(5) TCID(50)/mL). The specificity analysis results showed that this new ICA had no cross reaction in the presence of other porcine viruses. The ICA was also validated for the detection of PEDV in swine stool samples with little interference from swine stool. To compare its accuracy to other traditional detection methods, 27 swine stool samples from south of China were investigated with the new developed ICA, commercial strip and RT-PCR. Results showed that the new ICA was more comparable to RT-PCR than commercial test strip. CONCLUSIONS: A new ICA based on mAbs prepared by CSFIA was developed in this study. It was a sensitive, specific and rapid method that could be used for on-site detection of PEDV and therefore was useful for the diagnosis and prevention of PED.

Administration of tannins in calves with diarrhea seemed to shorten the DDE in T by almost 4 days compared to C, suggesting an effective astringent action of chestnut tannins in the calf, as already reported in humans. The aim of the present study was to evaluate the effect of oral administration of chestnut tannins (Castanea sativa) in the treatment of calf neonatal diarrhea. Data concerning the weight at birth and at the third week of life, the age of diarrhea onset and the T0 fecal scores (T0-FS) recorded for both groups were assessed for normal distribution by the Shapiro-Wilk normality test and then a Mann-Whitney test was applied in order to verify differences between the two groups at the inclusion time [28] . abstract: BACKGROUND: Neonatal calf diarrhea is generally caused by infectious agents and is a very common disease in bovine practice, leading to substantial economic losses. Tannins are known for their astringent and anti-inflammatory properties in the gastro-enteric tract. The aim of this study was to evaluate the effect of the oral administration of chestnut tannins (Castanea sativa Mill.) in order to reduce the duration of calf neonatal diarrhea. Twenty-four Italian Friesian calves affected by neonatal diarrhea were included. The duration of the diarrheic episode (DDE) was recorded and the animals were divided into a control group (C), which received Effydral® in 2 l of warm water, and a tannin-treated group (T), which received Effydral® in 2 l of warm water plus 10 g of extract of chestnut tannins powder. A Mann-Whitney test was performed to verify differences for the DDE values between the two groups. RESULTS: The DDE was significantly higher in group C than in group T (p = 0.02), resulting in 10.1 ± 3.2 and 6.6 ± 3.8 days, respectively. CONCLUSIONS: Phytotherapic treatments for various diseases have become more common both in human and in veterinary medicine, in order to reduce the presence of antibiotic molecules in the food chain and in the environment. Administration of tannins in calves with diarrhea seemed to shorten the DDE in T by almost 4 days compared to C, suggesting an effective astringent action of chestnut tannins in the calf, as already reported in humans. The use of chestnut tannins in calves could represent an effective, low-impact treatment for neonatal diarrhea. url: https://doi.org/10.1186/s12917-018-1549-2 doi: 10.1186/s12917-018-1549-2 id: cord-000820-5b29wtim author: Borriello, Giorgia title: Diversity of Salmonella spp. serovars isolated from the intestines of water buffalo calves with gastroenteritis date: 2012-10-25 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Salmonellosis in water buffalo (Bubalus bubalis) calves is a widespread disease characterized by severe gastrointestinal lesions, profuse diarrhea and severe dehydration, occasionally exhibiting a systemic course. Several Salmonella serovars seem to be able to infect water buffalo, but Salmonella isolates collected from this animal species have been poorly characterized. In the present study, the prevalence of Salmonella spp. in water buffalo calves affected by lethal gastroenteritis was assessed, and a polyphasic characterization of isolated strains of S. Typhimurium was performed. RESULTS: The microbiological analysis of the intestinal contents obtained from 248 water buffalo calves affected by lethal gastroenteritis exhibited a significant prevalence of Salmonella spp. (25%), characterized by different serovars, most frequently Typhimurium (21%), Muenster (11%), and Give (11%). The 13 S. Typhimurium isolates were all associated with enterocolitis characterized by severe damage of the intestine, and only sporadically isolated with another possible causative agent responsible for gastroenteritis, such as Cryptosporidium spp., Rotavirus or Clostridium perfringens. Other Salmonella isolates were mostly isolated from minor intestinal lesions, and often (78% of cases) isolated with other microorganisms, mainly toxinogenic Escherichia coli (35%), Cryptosporidium spp. (20%) and Rotavirus (10%). The S. Typhimurium strains were characterized by phage typing and further genotyped by polymerase chain reaction (PCR) detection of 24 virulence genes. The isolates exhibited nine different phage types and 10 different genetic profiles. Three monophasic S. Typhimurium (B:4,12:i:-) isolates were also found and characterized, displaying three different phage types and three different virulotypes. The molecular characterization was extended to the 7 S. Muenster and 7 S. Give isolates collected, indicating the existence of different virulotypes also within these serovars. Three representative strains of S. Typhimurium were tested in vivo in a mouse model of mixed infection. The most pathogenic strain was characterized by a high number of virulence factors and the presence of the locus agfA, coding for a thin aggregative fimbria. CONCLUSIONS: These results provide evidence that Salmonella is frequently associated with gastroenteritis in water buffalo calves, particularly S. Typhimurium. Moreover, the variety in the number and distribution of different virulence markers among the collected S. Typhimurium strains suggests that within this serovar there are different pathotypes potentially responsible for different clinical syndromes. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3514206/ doi: 10.1186/1746-6148-8-201 id: cord-321739-dnuu6jok author: Bowman, Andrew S title: Investigating the introduction of porcine epidemic diarrhea virus into an Ohio swine operation date: 2015-02-15 words: 4726.0 sentences: 204.0 pages: flesch: 53.0 cache: ./cache/cord-321739-dnuu6jok.txt txt: ./txt/cord-321739-dnuu6jok.txt summary: The Ohio swine operation (Figure 1 ), consisting of 3 multi-site, farrow-to-finish production flows (referred to as flows A-C, each having two breed-wean sites) and a multiplier herd (referred to as D, with a single breedwean site) had no prior cases of PEDV and was determined to have effective biosecurity measures in place evidenced by the absence of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) during more than the prior seven years. Beyond the sow unit, a wean-to-finish barn in flow A that received pigs on January 10 th from both flow A breed-wean units (A1 and A2) reported loose stools on January 12 th and had confirmation of PEDV with RT-PCR positive fecal samples collected the same day. On that same day, an oral fluid sample from one of the nurseries in flow B that received pigs from both flow B breed-wean units (B1 and B2) on January 15 th , 17 th , and 20 th , 2014 tested PEDV PCR positive ( Figure 1B ). abstract: BACKGROUND: Porcine Epidemic Diarrhea virus (PEDV) is a highly transmissible coronavirus that causes a severe enteric disease that is particularly deadly for neonatal piglets. Since its introduction to the United States in 2013, PEDV has spread quickly across the country and has caused significant financial losses to pork producers. With no fully licensed vaccines currently available in the United States, prevention and control of PEDV disease is heavily reliant on biosecurity measures. Despite proven, effective biosecurity practices, multiple sites and production stages, within and across designated production flows in an Ohio swine operation broke with confirmed PEDV in January 2014, leading the producer and attending veterinarian to investigate the route of introduction. CASE PRESENTATION: On January 12, 2014, several sows within a production flow were noted with signs of enteric illness. Within a few days, illness had spread to most of the sows in the facility and was confirmed by RT-PCR to be PEDV. Within a short time period, confirmed disease was present on multiple sites within and across breeding and post weaning production flows of the operation and mortality approached 100% in neonatal piglets. After an epidemiologic investigation, an outsourced, pelleted piglet diet was identified for assessment, and a bioassay, where naïve piglets were fed the suspected feed pellets, was initiated to test the pellets for infectious PEDV. CONCLUSIONS: The epidemiological investigation provided strong evidence for contaminated feed as the source of the outbreak. In addition, feed pellets collected from unopened bags at the affected sites tested positive for PEDV using RT-PCR. However, the bioassay study was not able to show infectivity when feeding the suspected feed pellets to a small number of naïve piglets. The results highlight the critical need for surveillance of feed and feed components to further define transmission avenues in an effort to limit the spread of PEDV throughout the U.S. swine industry. url: https://doi.org/10.1186/s12917-015-0348-2 doi: 10.1186/s12917-015-0348-2 id: cord-259710-qrht9tq3 author: Burimuah, Vitus title: Molecular-based cross-species evaluation of bovine coronavirus infection in cattle, sheep and goats in Ghana date: 2020-10-27 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Apart from the huge worldwide economic losses often occasioned by bovine coronavirus (BCoV) to the livestock industry, particularly with respect to cattle rearing, continuous surveillance of the virus in cattle and small ruminants is essential in monitoring variations in the virus that could enhance host switching. In this study, we collected rectal swabs from a total of 1,498 cattle, sheep and goats. BCoV detection was based on reverse transcriptase polymerase chain reaction. Sanger sequencing of the partial RNA-dependent RNA polymerase (RdRp) region for postive samples were done and nucleotide sequences were compared with homologous sequences from the GenBank. RESULTS: The study reports a BCoV prevalence of 0.3%, consisting of 4 positive cases; 3 goats and 1 cattle. Less than 10% of all the animals sampled showed clinical signs such as diarrhea and respiratory distress except for high temperature which occurred in > 1000 of the animals. However, none of the 4 BCoV positive animals manifested any clinical signs of the infection at the time of sample collection. Bayesian majority-rule cladogram comparing partial and full length BCoV RdRp genes obtained in the study to data from the GenBank revealed that the sequences obtained from this study formed one large monophyletic group with those from different species and countries. The goat sequences were similar to each other and clustered within the same clade. No major variations were thus observed between our isolates and those from elsewhere. CONCLUSIONS: Given that Ghana predominantly practices the extensive and semi-intensive systems of animal rearing, our study highlights the potential for spillover of BCoV to small ruminants in settings with mixed husbandry and limited separation between species. url: https://doi.org/10.1186/s12917-020-02606-x doi: 10.1186/s12917-020-02606-x id: cord-337868-d2uvdnii author: Castanheira, Pedro title: Molecular and serological surveillance of canine enteric viruses in stray dogs from Vila do Maio, Cape Verde date: 2014-04-23 words: 3965.0 sentences: 207.0 pages: flesch: 51.0 cache: ./cache/cord-337868-d2uvdnii.txt txt: ./txt/cord-337868-d2uvdnii.txt summary: Although a higher mortality rate is observed in animals with multiple infections with other pathogens such as CPV-2, canine adenovirus type 1 and CDV, CCoV represents per si a major infectious agent responsible for several epidemics [13, 14] . In order to detect the presence of canine viruses on Maio island, samples collected from stray dogs from Vila do Maio were tested for canine parvovirus (CPV), canine distemper virus (CDV) and canine coronavirus (CCoV), to estimate the viral prevalence in this population and investigate the role of these animals in the maintenance and potential spread of common viral pathogens. This study describes for the first time, the shedding of three common enteric canine viruses, CPV, CDV and CCoV, in 178 stray dogs from Vila do Maio, Cape Verde and reports data on CPV and CDV seroprevalence. In addition, the high mortality rates caused by CDV contribute to the low virus spread in canine populations since the animals that succumbed to infection stop shedding. abstract: BACKGROUND: Infections caused by canine parvovirus, canine distemper virus and canine coronavirus are an important cause of mortality and morbidity in dogs worldwide. Prior to this study, no information was available concerning the incidence and prevalence of these viruses in Cape Verde archipelago. RESULTS: To provide information regarding the health status of the canine population in Vila do Maio, Maio Island, Cape Verde, 53 rectal swabs were collected from 53 stray dogs during 2010 and 93 rectal swabs and 88 blood samples were collected from 125 stray dogs in 2011. All rectal swabs (2010 n = 53; 2011 n = 93) were analysed for the presence of canine parvovirus, canine distemper virus and canine coronavirus nucleic acids by quantitative PCR methods. Specific antibodies against canine distemper virus and canine parvovirus were also assessed (2011 n = 88). From the 2010 sampling, 43.3% (23/53) were positive for canine parvovirus DNA, 11.3% (6/53) for canine distemper virus RNA and 1.9% (1/53) for canine coronavirus RNA. In 2011, the prevalence values for canine parvovirus and canine coronavirus were quite similar to those from the previous year, respectively 44.1% (41/93), and 1.1% (1/93), but canine distemper virus was not detected in any of the samples analysed (0%, 0/93). Antibodies against canine parvovirus were detected in 71.6% (63/88) blood samples and the seroprevalence found for canine distemper virus was 51.1% (45/88). CONCLUSIONS: This study discloses the data obtained in a molecular and serological epidemiological surveillance carried out in urban populations of stray and domestic animals. Virus transmission and spreading occurs easily in large dog populations leading to high mortality rates particularly in unvaccinated susceptible animals. In addition, these animals can act as disease reservoirs for wild animal populations by occasional contact. Identification of susceptible wildlife of Maio Island is of upmost importance to evaluate the risk of pathogen spill over from domestic to wild animals in Cape Verde and to evaluate the associated threat to the wild susceptible species. url: https://doi.org/10.1186/1746-6148-10-91 doi: 10.1186/1746-6148-10-91 id: cord-343324-qriqtv0y author: Charoenkul, Kamonpan title: First detection and genetic characterization of canine Kobuvirus in domestic dogs in Thailand date: 2019-07-19 words: 2542.0 sentences: 173.0 pages: flesch: 61.0 cache: ./cache/cord-343324-qriqtv0y.txt txt: ./txt/cord-343324-qriqtv0y.txt summary: Genetic and phylogenetic analyses showed that whole genomes of Thai CaKoVs were closely related to Chinese CaKoVs with highest 99.5% amino acid identity suggesting possible origin of CaKoVs in Thailand.

We compared the nucleotide and deduced amino acid sequences of Thai CaKoVs against those of reference viruses from the US, UK, Italy, China, and Korea (Tables 2 and 3 most variable region of VP1 is position 201-243, especially proline rich region. abstract: BACKGROUND: Canine Kobuvirus (CaKoV) has been detected both in healthy and diarrheic dogs and in asymptomatic wild carnivores. In this study, we conducted a survey of CaKoV at small animal hospitals in Bangkok and vicinity of Thailand during September 2016 to September 2018. RESULTS: Three hundred and seven rectal swab samples were collected from healthy dogs (n = 55) and dogs with gastroenteritis symptoms (n = 252). Of 307 swab samples tested by using one-step RT-PCR specific to 3D gene, we found CaKoV positivity at 17.59% (54/307). CaKoVs could be detected in both sick (19.44%) and healthy (9.09%) animals. In relation to age group, CaKoV could be frequently detected in younger dogs (25.45%). Our result showed no seasonal pattern of CaKoV infection in domestic dogs. In this study, we characterized CaKoVs by whole genome sequencing (n = 4) or 3D and VP1 gene sequencing (n = 8).

The proportional morbidity ratio of FIV to FeLV infection was estimated for each administrative region and its geographic distribution pattern was visualized by a choropleth map. The proportional morbidity ratio (PMR) of FIV to FeLV infection was estimated for each administrative region and a choropleth disease map was used to visualize the spatial pattern of PMR. Areas of relative FIV excess identified by the spatial scan statistic were visualized by highlighting the boundaries of the states included in the most likely cluster on a choropleth map of the PMR of FIV to FeLV infection. In this study we have identified geographical patterns in the distribution of the proportional morbidity ratio of FIV to FeLV infection among cats in the 49 administrative regions of the US over the period 2000 to 2011. abstract: BACKGROUND: Although feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) have similar risk factors and control measures, infection rates have been speculated to vary in geographic distribution over North America. Since both infections are endemic in North America, it was assumed as a working hypothesis that their geographic distributions were similar. Hence, the purpose of this exploratory analysis was to investigate the comparative geographical distribution of both viral infections. Counts of FIV (n=17,108) and FeLV (n=30,017) positive serology results (FIV antibody and FeLV ELISA) were obtained for 48 contiguous states and District of Columbia of the United States of America (US) from the IDEXX Laboratories website. The proportional morbidity ratio of FIV to FeLV infection was estimated for each administrative region and its geographic distribution pattern was visualized by a choropleth map. Statistical evidence of an excess in the proportional morbidity ratio from unity was assessed using the spatial scan test under the normal probability model. RESULTS: This study revealed distinct spatial distribution patterns in the proportional morbidity ratio suggesting the presence of one or more relevant and geographically varying risk factors. The disease map indicates that there is a higher prevalence of FIV infections in the southern and eastern US compared to FeLV. In contrast, FeLV infections were observed to be more frequent in the western US compared to FIV. The respective excess in proportional morbidity ratio was significant with respect to the spatial scan test (p < 0.05). CONCLUSIONS: The observed variability in the geographical distribution of the proportional morbidity ratio of FIV to FeLV may be related to the presence of an additional or unique, but yet unknown, spatial risk factor. Putative factors may be geographic variations in specific virus strains and rate of vaccination. Knowledge of these factors and the geographical distributions of these infections can inform recommendations for testing, management and prevention. However, further studies are required to investigate the potential association of these factors with FIV and FeLV. url: https://doi.org/10.1186/1746-6148-9-2 doi: 10.1186/1746-6148-9-2 id: cord-346467-a0r4xh1c author: Cornelissen, Jan B.

The results reported among the 47 diarrhoeic samples analysed include representatives of 12 virus species corresponding to 8 genera of RNA viruses (Additional file 1): Kobuvirus, Rotavirus (RVA, RVB and RVC), Sapovirus (SAV), Mamastrovirus (Porcine Astrovirus types 3 -AstV3 -, 4 -AstV4 -and 5 -AstV5 -), Alphacoronavirus (PEDV), Enterovirus (Enterovirus G, EntVG), Pasivirus (PasiV) and Posavirus (PosaV). Regarding KobuV, our results also agree with an increased prevalence of this agent observed in cases of diarrhoea in suckling piglets worldwide: Brazil [22] , Korea [29] and Vietnam [30] ; despite several (See figure on previous page.) Fig. 5 Neighbor-joining phylogenetic tree based on the p-distance among the nucleotide sequences of the VP7 segment for Rotavirus B. abstract: BACKGROUND: Diarrhoea is a major cause of death in neonate pigs and most of the viruses that cause it are RNA viruses. Next Generation Sequencing (NGS) deeply characterize the genetic diversity among rapidly mutating virus populations at the interspecific as well as the intraspecific level. The diversity of RNA viruses present in faeces of neonatal piglets suffering from diarrhoea in 47 farms, plus 4 samples from non-diarrhoeic piglets has been evaluated by NGS. Samples were selected among the cases submitted to the Veterinary Diagnostic Laboratories of Infectious Diseases of the Universitat Autònoma de Barcelona (Barcelona, Spain) and Universidad de León (León, Spain). RESULTS: The analyses identified the presence of 12 virus species corresponding to 8 genera of RNA viruses. Most samples were co-infected by several viruses. Kobuvirus and Rotavirus were more commonly reported, with Sapovirus, Astrovirus 3, 4 and 5, Enterovirus G, Porcine epidemic diarrhoea virus, Pasivirus and Posavirus being less frequently detected. Most sequences showed a low identity with the sequences deposited in GenBank, allowing us to propose several new VP4 and VP7 genotypes for Rotavirus B and Rotavirus C. CONCLUSIONS: Among the cases analysed, Rotaviruses were the main aetiological agents of diarrhoea in neonate pigs. Besides, in a small number of cases Kobuvirus and Sapovirus may also have an aetiological role. Even most animals were co-infected in early life, the association with enteric disease among the other examined viruses was unclear. The NGS method applied successfully characterized the RNA virome present in faeces and detected a high level of unreported intraspecific diversity. url: https://www.ncbi.nlm.nih.gov/pubmed/31805938/ doi: 10.1186/s12917-019-2204-2 id: cord-306502-jkqg1qal author: Dee, Scott title: An evaluation of contaminated complete feed as a vehicle for porcine epidemic diarrhea virus infection of naïve pigs following consumption via natural feeding behavior: proof of concept date: 2014-08-05 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Since its initial detection in May 2013, porcine epidemic diarrhea virus (PEDV) has spread rapidly throughout the US swine industry. Initially, contaminated feed was proposed as a risk factor for PEDV; however, data were not available to support this theory. Here we provide proof of concept of this risk by describing a novel means for recovering PEDV-contaminated complete feed material from commercial swine sites and conducting an in vivo experiment to prove its infectivity. RESULTS: For on-farm detection of PEDV RNA in feed, paint rollers were used to collect material from at-risk feed bins from 3 clinically affected breeding herds. This material was tested by PCR and determined to be positive for PEDV-RNA (Ct = 19.50-22.20 range). To test infectivity, this material was pooled (Ct = 20.65) and a Treatment group of 3-week old PEDV-naïve piglets were allowed to consume it via natural feeding behavior. For the purpose of a Positive control, piglets were allowed to ingest feed spiked with stock PEDV (Ct = 18.23) while the negative control group received PEDV-free feed. Clinical signs of PEDV infection (vomiting and diarrhea) and viral shedding were observed in both the Positive control and Treatment group’ post-consumption with virus and microscopic lesions detected in intestinal samples No evidence of infection was observed in the Negative controls. CONCLUSIONS: These data provide proof of concept that contaminated complete feed can serve as a vehicle for PEDV infection of naïve pigs using natural feeding behavior. url: https://www.ncbi.nlm.nih.gov/pubmed/25091641/ doi: 10.1186/s12917-014-0176-9 id: cord-308170-uqezwbzn author: Dee, Scott title: An evaluation of a liquid antimicrobial (Sal CURB®) for reducing the risk of porcine epidemic diarrhea virus infection of naïve pigs during consumption of contaminated feed date: 2014-09-25 words: 3164.0 sentences: 168.0 pages: flesch: 60.0 cache: ./cache/cord-308170-uqezwbzn.txt txt: ./txt/cord-308170-uqezwbzn.txt summary: title: An evaluation of a liquid antimicrobial (Sal CURB®) for reducing the risk of porcine epidemic diarrhea virus infection of naïve pigs during consumption of contaminated feed For the purpose of a positive control, a separate group of piglets was allowed to ingest non-treated (Sal CURB®-free) feed also spiked with stock PEDV (Ct = 25.22). Clinical signs of PEDV infection (vomiting and diarrhea) and viral shedding in feces were observed in the positive control group 2–3 days post-consumption of non-treated feed. Furthermore, the results from the positive control group provide additional proof of concept regarding the ability of contaminated feed to serve as a risk factor for PEDV infection of naïve piglets. The results of this study provide initial proof of concept that the application of a liquid antimicrobial product (Sal CURB®) reduced the risk of PEDV infection through contaminated feed. abstract: BACKGROUND: Since its initial detection in May 2013, porcine epidemic diarrhea virus (PEDV) has spread rapidly throughout the US swine industry. Recently, contaminated feed was confirmed as a vehicle for PEDV infection of naïve piglets. This research provides in vivo data supporting the ability of a liquid antimicrobial product to reduce this risk. RESULTS: Sal CURB® (Kemin Industries, Des Moines, IA, USA) is a FDA-approved liquid antimicrobial used to control Salmonella contamination in poultry and swine diets. To test its effect against PEDV, Sal CURB®-treated feed was spiked with a stock isolate of PEDV (Ct = 25.22), which PEDV-naïve piglets were allowed to ingest via natural feeding behavior (ad libitum) for a 14-day period. For the purpose of a positive control, a separate group of piglets was allowed to ingest non-treated (Sal CURB®-free) feed also spiked with stock PEDV (Ct = 25.22). A negative control group received PEDV-free feed. Clinical signs of PEDV infection (vomiting and diarrhea) and viral shedding in feces were observed in the positive control group 2–3 days post-consumption of non-treated feed. In contrast, no evidence of infection was observed in pigs fed Sal CURB®-treated feed or in the negative controls throughout the 14-day study period. In addition, the Sal CURB®-treated feed samples had higher (p < 0.0001) mean PEDV Ct values than samples from the positive control group. CONCLUSIONS: These data provide proof of concept that feed treated with Sal CURB® can serve as a means to reduce the risk of PEDV infection through contaminated feed. Furthermore, the results from the positive control group provide additional proof of concept regarding the ability of contaminated feed to serve as a risk factor for PEDV infection of naïve piglets. url: https://www.ncbi.nlm.nih.gov/pubmed/25253192/ doi: 10.1186/s12917-014-0220-9 id: cord-348522-r7ev9br6 author: Englund, Stina title: The occurrence of Chlamydia spp. in pigs with and without clinical disease date: 2012-01-26 words: 3890.0 sentences: 225.0 pages: flesch: 54.0 cache: ./cache/cord-348522-r7ev9br6.txt txt: ./txt/cord-348522-r7ev9br6.txt summary: By immunohistochemistry, 32 of 44 samples were positive and a significant relationship was detected between macroscopically visible intestinal lesions and a high degree of infection.

Intestinal lesions caused by a strain of Chlamydia suis in weanling pigs infected at 21 days of age abstract: BACKGROUND: Within the genera Chlamydia, the development of refined diagnostic techniques has allowed the identification of four species that are capable of infecting pigs. The epidemiology, clinical, and zoonotic impacts of these species are however largely unknown. The study aimed to investigate the presence of Chlamydia spp. in the intestines of growing pigs and in conjunctival swabs from finisher pigs, and relate the findings to clinical signs. RESULTS: By histology, 20 of 48 pigs had intestinal lesions that may be consistent with chlamydial infection. By PCR, forty-six of the pigs were positive whereas two samples were inhibited. Sequencing of 19 DNA extracts identified these as Chlamydia suis. By immunohistochemistry, 32 of 44 samples were positive and a significant relationship was detected between macroscopically visible intestinal lesions and a high degree of infection. By real-time PCR, a significant difference was detected between pigs with and without conjunctivitis when a Ct value of 36 was employed but not when a Ct value of 38 was employed. CONCLUSIONS: Chlamydia suis was demonstrated in most samples and overall, no correlation to clinical signs was detected. However, a correlation was noted between samples with a high degree of infection and the presence of clinical signs. It is possible, that the intensive pig production systems studied might predispose for the transmission and maintenance of the infection thus increasing the infectious load and the risk for disease in the pig. url: https://www.ncbi.nlm.nih.gov/pubmed/22280482/ doi: 10.1186/1746-6148-8-9 id: cord-271392-u6vme2c8 author: Eussen, Björn G.M. title: Stimulating collaboration between human and veterinary health care professionals date: 2017-06-13 words: 7389.0 sentences: 365.0 pages: flesch: 40.0 cache: ./cache/cord-271392-u6vme2c8.txt txt: ./txt/cord-271392-u6vme2c8.txt summary: RESULTS: Based on Gaertner and Dovidio''s Common Ingroup Identity Model, a number of questionnaires were designed and tested; with PROGRESS, the relation between collaboration and common goal was assessed, mediated by decategorization, recategorization, mutual differentiation and knowledge sharing. However, in terms of making room for the bigger collective goal alongside their responsibilities related to the day-to-day care of their own patients, human and veterinary healthcare professionals often see insufficient added value [14] , even though a greater awareness of the added value associated with collaboration would ultimately result in improved care [5, 15, 16] . The current study will not only indicate whether the Common Ingroup Identity Model is useful for the respective groups of healthcare professionals, but it will also quantitatively assess the relationships between the common goal and collaboration in combination with associated mediating factors. One Health as a common goal has a positive effect on collaboration between human and veterinary healthcare professionals. abstract: BACKGROUND: Despite the need to control outbreaks of (emerging) zoonotic diseases and the need for added value in comparative/translational medicine, jointly addressed in the One Health approach [One health Initiative (n.d.a). About the One Health Initiative. http://www.onehealthinitiative.com/about.php. Accessed 13 September 2016], collaboration between human and veterinary health care professionals is limited. This study focuses on the social dilemma experienced by health care professionals and ways in which an interdisciplinary approach could be developed. RESULTS: Based on Gaertner and Dovidio’s Common Ingroup Identity Model, a number of questionnaires were designed and tested; with PROGRESS, the relation between collaboration and common goal was assessed, mediated by decategorization, recategorization, mutual differentiation and knowledge sharing. This study confirms the Common Ingroup Identity Model stating that common goals stimulate collaboration. Decategorization and mutual differentiation proved to be significant in this relationship; recategorization and knowledge sharing mediate this relation. CONCLUSIONS: It can be concluded that the Common Ingroup Identity Model theory helps us to understand how health care professionals perceive the One Health initiative and how they can intervene in this process. In the One Health approach, professional associations could adopt a facilitating role. url: https://www.ncbi.nlm.nih.gov/pubmed/28610617/ doi: 10.1186/s12917-017-1072-x id: cord-329148-zs18ez5q author: Geng, Yunyun title: Development of real-time recombinase polymerase amplification assay for rapid and sensitive detection of canine parvovirus 2 date: 2017-11-06 words: 3889.0 sentences: 193.0 pages: flesch: 55.0 cache: ./cache/cord-329148-zs18ez5q.txt txt: ./txt/cord-329148-zs18ez5q.txt summary: title: Development of real-time recombinase polymerase amplification assay for rapid and sensitive detection of canine parvovirus 2 With the advances in molecular detection techniques, a substantial number of gene amplification-based assays have been described for CPV-2 diagnosis such as polymerase chain reaction (PCR), nested PCR, real-time PCR, reverse-transcription loop-mediated isothermal amplification (RT-LAMP) and insulated isothermal PCR (iiPCR) [9] [10] [11] [12] [13] [14] [15] . Based on our previous study, we developed here a real-time RPA assay for simple, rapid, convenient and POC detection of CPV-2, which utilizes an exo probe and a portable, userfriendly POC tube scanner. A probit regression analysis using the results of eight complete molecular standard runs calculated that the limit of detection (LOD) of the real-time RPA was 10 1 copies per reaction in 95% of cases (Fig. 2c) , which was the same as that of the real-time PCR applied in the study (data not shown). abstract: BACKGROUND: Canine parvovirus 2, a linear single-stranded DNA virus belonging to the genus Parvovirus within the family Parvoviridae, is a highly contagious pathogen of domestic dogs and several wild canidae species. Early detection of canine parvovirus (CPV-2) is crucial to initiating appropriate outbreak control strategies. Recombinase polymerase amplification (RPA), a novel isothermal gene amplification technique, has been developed for the molecular detection of diverse pathogens. In this study, a real-time RPA assay was developed for the detection of CPV-2 using primers and an exo probe targeting the CPV-2 nucleocapsid protein gene. RESULTS: The real-time RPA assay was performed successfully at 38 °C, and the results were obtained within 4–12 min for 10(5)–10(1) molecules of template DNA. The assay only detected CPV-2, and did not show cross-detection of other viral pathogens, demonstrating a high level of specificity. The analytical sensitivity of the real-time RPA was 10(1) copies/reaction of a standard DNA template, which was 10 times more sensitive than the common RPA method. The clinical sensitivity of the real-time RPA assay matched 100% (n = 91) to the real-time PCR results. CONCLUSION: The real-time RPA assay is a simple, rapid, reliable and affordable method that can potentially be applied for the detection of CPV-2 in the research laboratory and point-of-care diagnosis.

While considerable attention has been paid to bacterial contamination of commercial pet food, few literature studies have investigated foodborne disease in companion animals. Salmonellosis is reported to be infrequent in cats but no known data or studies estimating feline salmonellosis are available or large-scale epidemiological studies assessing Salmonella risk factors. CASE PRESENTATION: Two highly suspected cases of salmonellosis in two cats fed with a commercial frozen poultry RMBD are presented, for the first time from the same household. The clinical presentation, diagnostics, treatment and follow-up are reported and the zoonotic implications are discussed. CONCLUSIONS: This case highlights the health risks posed to both animals and owners by feeding RMBD to pets, and suggests that these risks should be considered by veterinary practitioners. url: https://www.ncbi.nlm.nih.gov/pubmed/28738871/ doi: 10.1186/s12917-017-1143-z id: cord-325101-9qslo6qh author: Gizzi, Aline Baumann da Rocha title: Presence of infectious agents and co-infections in diarrheic dogs determined with a real-time polymerase chain reaction-based panel date: 2014-01-16 words: 5156.0 sentences: 239.0 pages: flesch: 50.0 cache: ./cache/cord-325101-9qslo6qh.txt txt: ./txt/cord-325101-9qslo6qh.txt summary: Although many pathogens have been individually detected with real-time polymerase chain reaction (PCR), a comprehensive panel of agents that cause diarrhea in privately owned dogs has not yet been established. Therefore, the aim of this study was to investigate pathogenic co-infections in populations of diarrheic and control owned dogs using a real-time PCR analysis of a panel of diarrhea-causing agents. The most prevalent agent involved in co-infections was canine parvovirus type 2 (CPV-2), and 21/36 (58.3%) of the diarrheic samples positive for CPV-2 were associated with others agents, most commonly with Clostridium perfringens alpha toxin (CPA), Cryptosporidium spp., and Giardia spp. The detection of individual pathogens in the panel with real-time PCR (Table 3) showed that CPA was the most prevalent pathogen in the fecal samples, infecting 40/104 (38.5%) diarrheic dogs and 6/43 (14.0%) control dogs, and the difference between the groups was highly statistically significant (P = 0.006). abstract: BACKGROUND: Infectious diarrhea can be caused by bacteria, viruses, or protozoan organisms, or a combination of these. The identification of co-infections in dogs is important to determine the prognosis and to plan strategies for their treatment and prophylaxis. Although many pathogens have been individually detected with real-time polymerase chain reaction (PCR), a comprehensive panel of agents that cause diarrhea in privately owned dogs has not yet been established. The objective of this study was to use a real-time PCR diarrhea panel to survey the frequencies of pathogens and co-infections in owned dogs attended in a veterinary hospital with and without diarrhea, as well the frequency in different countries. Feces samples were tested for canine distemper virus, canine coronavirus, canine parvovirus type 2 (CPV-2), Clostridium perfringens alpha toxin (CPA), Cryptosporidium spp., Giardia spp., and Salmonella spp. using molecular techniques. RESULTS: In total, 104 diarrheic and 43 control dogs that were presented consecutively at a major private veterinary hospital were included in the study. Overall, 71/104 (68.3%) dogs with diarrhea were positive for at least one pathogen: a single infection in 39/71 dogs (54.9%) and co-infections in 32/71 dogs (45.1%), including 21/32 dogs (65.6%) with dual, 5/32 (15.6%) with triple, and 6/32 (18.8%) with quadruple infections. In the control group, 13/43 (30.2%) dogs were positive, all with single infections only. The most prevalent pathogens in the diarrheic dogs were CPA (40/104 dogs, 38.5%), CPV-2 (36/104 dogs, 34.6%), and Giardia spp. (14/104 dogs, 13.5%). CPV-2 was the most prevalent pathogen in the dual co-infections, associated with CPA, Cryptosporidium spp., or Giardia spp. No statistical difference (P = 0.8374) was observed in the duration of diarrhea or the number of deaths (P = 0.5722) in the presence or absence of single or co-infections. CONCLUSIONS: Diarrheic dogs showed a higher prevalence of pathogen infections than the controls. Whereas the healthy dogs had only single infections, about half the diarrheic dogs had co-infections. Therefore, multiple pathogens should be investigated in dogs presenting with diarrhea. The effects of multiple pathogens on the disease outcomes remain unclear because the rate of death and the duration of diarrhea did not seem to be affected by these factors. url: https://www.ncbi.nlm.nih.gov/pubmed/24433321/ doi: 10.1186/1746-6148-10-23 id: cord-000518-78395e3t author: Gloster, John title: Normal variation in thermal radiated temperature in cattle: implications for foot-and-mouth disease detection date: 2011-11-21 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Thermal imagers have been used in a number of disciplines to record animal surface temperatures and as a result detect temperature distributions and abnormalities requiring a particular course of action. Some work, with animals infected with foot-and-mouth disease virus, has suggested that the technique might be used to identify animals in the early stages of disease. In this study, images of 19 healthy cattle have been taken over an extended period to determine hoof and especially coronary band temperatures (a common site for the development of FMD lesions) and eye temperatures (as a surrogate for core body temperature) and to examine how these vary with time and ambient conditions. RESULTS: The results showed that under UK conditions an animal's hoof temperature varied from 10°C to 36°C and was primarily influenced by the ambient temperature and the animal's activity immediately prior to measurement. Eye temperatures were not affected by ambient temperature and are a useful indicator of core body temperature. CONCLUSIONS: Given the variation in temperature of the hooves of normal animals under various environmental conditions the use of a single threshold hoof temperature will be at best a modest predictive indicator of early FMD, even if ambient temperature is factored into the evaluation. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3235061/ doi: 10.1186/1746-6148-7-73 id: cord-336902-iptfle2b author: Harada, Kazuki title: First case of Propionibacterium acnes urinary tract infection in a dog date: 2015-12-21 words: 1937.0 sentences: 128.0 pages: flesch: 47.0 cache: ./cache/cord-336902-iptfle2b.txt txt: ./txt/cord-336902-iptfle2b.txt summary: title: First case of Propionibacterium acnes urinary tract infection in a dog Urinary tract infections are common in dogs and are typically caused by various commensal bacteria.

CONCLUSION: To the best of our knowledge, this is the first case report of a dog with urinary tract infection caused by P. Propionibacterium acnes is an aerotolerant, anaerobic, Gram-positive, rod-shaped bacterium commonly isolated from humans. acnes has not been previously reported as a causative agent of UTI in dogs. [10] reported a case of a dog with osteomyelitis and arthritis due to Propionibacterium infection caused by a dog bite.

To the best of our knowledge, this is the first case report of a dog with UTI caused by P. abstract: BACKGROUND: Propionibacterium acnes has been rarely isolated as a commensal from dogs, but there is little evidence of pathogenicity. Urinary tract infections are common in dogs and are typically caused by various commensal bacteria. Here we present the first case report of a urinary tract infection caused by P. acnes. CASE PRESENTATION: A 6-year-old female Japanese Shiba Inu was hospitalized for polyuria, polydipsia, and severe hematuria. At admission, blood tests revealed leukocytosis, slight anemia, decreased albumin, and slightly elevated blood urea nitrogen. Computerized tomography showed gas accumulation on the inner side of the bladder wall. Urinalysis revealed proteinuria and bilirubinuria without glycosuria. The urine sediment contained large numbers of erythrocytes and leukocytes. Additionally, rod-shaped bacteria were detected by Diff-Quik staining. Enrofloxacin and metronidazole were administered empirically; however, the renal function declined sharply and the patient died 2 days later. Bacteriological examination revealed that the causative agent was Propionibacterium acnes, which was identified as sequence type 53 via multilocus sequence typing. This isolate showed high susceptibility to ampicillin, amoxicillin/clavulanic acid, cefoxitin, imipenem, clindamycin, tetracycline, chloramphenicol, and enrofloxacin, but was resistant to metronidazole. CONCLUSION: To the best of our knowledge, this is the first case report of a dog with urinary tract infection caused by P. acnes. url: https://doi.org/10.1186/s12917-015-0620-5 doi: 10.1186/s12917-015-0620-5 id: cord-298052-mbg6e2j1 author: Hardstaff, Jo L title: Livestock trade networks for guiding animal health surveillance date: 2015-04-01 words: 6509.0 sentences: 304.0 pages: flesch: 52.0 cache: ./cache/cord-298052-mbg6e2j1.txt txt: ./txt/cord-298052-mbg6e2j1.txt summary: Very few shipments of weaned cattle, sheep and goats require a rest period of 24 hours (Additional file 1), whereas many unweaned animals would require a 24 hour break in their journey from their point of origin to their Figure 1 The outdegree is shown against the indegree for the trade of cattle for different purposes on the left column of the table and the geographical movement across Europe is shown on the right column of the table.

Annually millions of animals are moved across Europe for the purposes of breeding, fattening and slaughter. Data on the number of animals moved were obtained from the Directorate General Sanco (DG Sanco) for 2011. These were converted to livestock units to enable direct comparison across species and their movements were mapped, used to calculate the indegrees and outdegrees of 27 European countries and the density and transitivity of movements within Europe. This provided the opportunity to discuss surveillance of European livestock movement taking into account stopping points en-route. RESULTS: High density and transitivity of movement for registered equines, breeding and fattening cattle, breeding poultry and pigs for breeding, fattening and slaughter indicates that hazards have the potential to spread quickly within these populations. This is of concern to highly connected countries particularly those where imported animals constitute a large proportion of their national livestock populations, and have a high indegree. The transport of poultry (older than 72 hours) and unweaned animals would require more rest breaks than the movement of weaned animals, which may provide more opportunities for disease transmission. Transitivity is greatest for animals transported for breeding purposes with cattle, pigs and poultry having values of over 50%. CONCLUSIONS: This paper demonstrated that some species (pigs and poultry) are traded much more frequently and at a larger scale than species such as goats. Some countries are more vulnerable than others due to importing animals from many countries, having imported animals requiring rest-breaks and importing large proportions of their national herd or flock. Such knowledge about the vulnerability of different livestock systems related to trade movements can be used to inform the design of animal health surveillance systems to facilitate the trade in animals between European member states.

Due to this, the current study aimed to determine antibody prevalence against BRSV and investigate some risk factors associated with BRSV seroprevalence in herds of an important milk producing region in São Paulo State, Brazil. Bovine respiratory syncytial virus seroprevalence and risk factors in endemic dairy cattle herds Prevalence of and risk factors for bovine respiratory syncytial virus (BRSV) infection in non-vaccinated dairy and dual-purpose cattle herds in Ecuador abstract: BACKGROUND: The cattle industry is one of the most important Brazilian agribusiness sectors and is a strong contributor to the national economy. Annually about 44.6 million calves are bred, which makes the optimal management of these animals extremely important. Several diseases can affect the initial stages of the bovine production chain, being the bovine respiratory syncytial virus (BRSV) one of the most relevant pathogens. This study aimed to characterize the epidemiology of BRSV infection in dairy cattle herds of São Paulo State, Brazil, using serological and risk factors analyses. For that, 1243 blood samples were collected of animals from 26 farms and a questionnaire about possible risk factors for BRSV prevalence was performed. The obtained blood sera were analyzed using virus neutralization test (VNT). RESULTS: VNT results showed high BRSV prevalence in dairy cattle herds, reaching 79.5% of seropositivity. The BRSV seroprevalence among studied farms ranged from 40 to 100%. The analysis of risk factors indicated that the age group and the occurrence of coinfection with bovine herpesvirus 1 (BoHV-1) and bovine viral diarrhea virus 1 (BVDV-1) should be associated with a higher prevalence of BRSV, while natural suckling was considered a protective factor. CONCLUSIONS: The study showed that adult animals over 1 year old are an important risk factor for the high seroprevalence of BRSV in herds. The high BRSV prevalence associated with BoHV-1 and BVDV-1 suggests that biosecurity measures should be applied in order to reduce viral dissemination. Additionally, the natural suckling may be an important management to protect calves from high BRSV seroprevalence. url: https://doi.org/10.1186/s12917-018-1535-8 doi: 10.1186/s12917-018-1535-8 id: cord-341141-bgrgzfoo author: Hou, Peili title: Rapid detection of infectious bovine Rhinotracheitis virus using recombinase polymerase amplification assays date: 2017-12-13 words: 4693.0 sentences: 234.0 pages: flesch: 51.0 cache: ./cache/cord-341141-bgrgzfoo.txt txt: ./txt/cord-341141-bgrgzfoo.txt summary: In this study, we described the development of a lateral flow dipstrip (LFD) of isothermal recombinase polymerase amplification (RPA) method for rapid detection of IBRV. The assay performance on acute-phase high fever clinical samples collected from cattle with no vaccine against IBRV, which were suspected to be infected with IBRV, was validated by detecting 24 fecal, 36 blood, 38 nasal swab and 8 tissue specimens, and compared with SYBR Green I based real-time PCR. The initial agarose gel result showed that Primer set 4-2F/4-2R/ 4-2LF yielded specific amplification efficiency for the RPA assay, and produced the expected size of the product was 250 base-pairs (Fig. 1a) , while the primers/probe targeting glycoprotein gB of the IBRV genome in this study could not be used to amplify effectively in the initial screen (data not show). abstract: BACKGROUND: Infectious bovine rhinotracheitis virus (IBRV) is a major pathogen in cattle and has led to significant economic losses to the dairy industry worldwide, and therefore a more optimal method for the rapid diagnosis of IBRV infection is highly needed. In this study, we described the development of a lateral flow dipstrip (LFD) of isothermal recombinase polymerase amplification (RPA) method for rapid detection of IBRV. METHODS: Distinct regions were selected as a candidate target for designing the LFD-RPA primers and probes. The analytical sensitivity of the RPA assay was determined using ten-fold serially diluted IBRV DNA. The specificity of the assay was assessed with other viral pathogens of cattle with similar clinic and other herpesviruses. The clinical performance was evaluated by testing 106 acute-phase high fever clinical specimens. RESULTS: RPA primers and probe were designed to target the specific conserved UL52 region fragment of IBRV. The detection could be completed at a constant temperature of 38 °C for 25 min, and the amplification products were easily visualized on a simple LFD. The detection limit of this assay was 5 copies per reaction of IBRV DNA and there was no cross-reactivity with other viruses causing bovine gastrointestinal and respiratory infections or other herpesviruses. The assay performance on acute-phase high fever clinical samples collected from cattle with no vaccine against IBRV, which were suspected to be infected with IBRV, was validated by detecting 24 fecal, 36 blood, 38 nasal swab and 8 tissue specimens, and compared with SYBR Green I based real-time PCR. The coincidence between IBRV LFD-RPA and real-time PCR was 100%. CONCLUSION: IBRV LFD-RPA was fast and much easier to serve as an alternative to the common measures used for IBRV diagnosis, as there is reduction in the use of instruments for identification of the infected animals. In addition, this assay may be the potential candidate to be used as point-of-care diagnostics in the field. url: https://www.ncbi.nlm.nih.gov/pubmed/29237466/ doi: 10.1186/s12917-017-1284-0 id: cord-001591-4ic2in3i author: Hu, Xiaoliang title: Molecular characterization and phylogenetic analysis of transmissible gastroenteritis virus HX strain isolated from China date: 2015-03-21 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Porcine transmissible gastroenteritis virus (TGEV) is the major etiological agent of viral enteritis and severe diarrhea in suckling piglets. In China, TGEV has caused great economic losses, but its role in epidemic diarrhea is unclear. This study aims to reveal the etiological role of TGEV in piglet diarrhea via molecular characterization and phylogenetic analysis. RESULTS: A TGEV-HX strain was isolated from China, and its complete genome was amplified, cloned, and sequenced. Sequence analysis indicated that it was conserved in the 5′ and 3′-non-translated regions, and there were no insertions or deletions in nonstructural genes, such as ORF1a, ORF1b, ORF3a, ORF3b, and ORF7, as well as in genes encoding structural proteins, such as the envelope (E), membrane (M), and nucleoprotein (N) proteins. Furthermore, the phylogenetic analysis indicated that the TGEV-HX strain was more similar to the TGEV Purdue cluster than to the Miller cluster. CONCLUSIONS: The present study described the isolation and genetic characterization of a TGEV-HX strain. The detailed analysis of the genetic variation of TGEVs in China provides essential information for further understanding the evolution of TGEVs. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4379598/ doi: 10.1186/s12917-015-0387-8 id: cord-347664-8shnkrto author: Kang, JeongWoo title: National post-market surveillance assessment of veterinary medicines in Korea during the past decade date: 2017-05-22 words: 2758.0 sentences: 137.0 pages: flesch: 44.0 cache: ./cache/cord-347664-8shnkrto.txt txt: ./txt/cord-347664-8shnkrto.txt summary: RESULTS: In this study, 1650 drugs for veterinary use were collected per year from each city and province in Korea and analysed for the quantity of active ingredients according to the "national post-market surveillance (NPMS) system" over the past decade. In Korea, national product quality control measures for veterinary medicine consists of pre-market government testing system (PMGTS) and the National Post-Market Surveillance (NPMS) assessment on veterinary medicine before and after the distribution. The Korea Animal and Plant Quarantine Agency (QIA) and each individual city/ province collects antibiotics, biologics and OCD currently in distribution from manufacturers, importers, and wholesalers of veterinary medicine, veterinary pharmacies, and veterinary hospitals in accordance with these testing plans. In particular, antibiotics have shown very dramatic decrease in noncompliance rates ( Table 2 ), illustrating that veterinary medicine manufacturing facilities and quality control standards have significantly improved over time [3, 4] . abstract: BACKGROUND: Veterinary medicines have been widely used for the prevention and treatment of diseases, growth promotion, and to promote feeding efficacy in livestock. As the veterinary medicine industry has steadily grown, it is crucial to set up a baseline for the quality of medicine as well as the insufficiency or excessiveness of the active ingredients in drug products to ensure the compliance, safety and efficacy of these medicines. Thus, the 10 years data of post-marketing quality control study was summarized to determine the rate and extent of non-compliance of these medicines and to establish baseline data for future quality control measures of veterinary medicine. RESULTS: In this study, 1650 drugs for veterinary use were collected per year from each city and province in Korea and analysed for the quantity of active ingredients according to the “national post-market surveillance (NPMS) system” over the past decade. The NPMS assessment was performed using liquid and gas chromatography, titration, UV/Vis spectrophotometry, and bioassays. A total of 358 cases were deemed noncompliant, with the average noncompliance rate for all medicine types being 2.0%. The average noncompliance rates for antibiotics, biologics and other chemical drugs except antibiotics (OCD) were 1.1%, 1.2%, and 3.0%, respectively. The first leading cause for noncompliant products was insufficient quantity of major ingredients (283 cases), and the second leading cause was the existence of excess amount of active ingredients (60 cases). Tylosin, spiramycin, ampicillin, tetracyclines and penicillins were most frequently found to be noncompliant among antibiotics. Among the OCD, the noncompliance was found commonly in vitamin A. CONCLUSION: The overall trend presented gradually decreasing violation rates, suggesting that the quality of veterinary medicines has improved. Consistent application of the NPMS assessment and the establishment of the Korea Veterinary Good Manufacturing Practice (KVGMP) will help to maintain the good quality of medicine. url: https://doi.org/10.1186/s12917-017-1054-z doi: 10.1186/s12917-017-1054-z id: cord-299988-jaekryq5 author: Karte, Claudia title: Re-emergence of porcine epidemic diarrhea virus in a piglet-producing farm in northwestern Germany in 2019 date: 2020-09-10 words: 3145.0 sentences: 194.0 pages: flesch: 54.0 cache: ./cache/cord-299988-jaekryq5.txt txt: ./txt/cord-299988-jaekryq5.txt summary: title: Re-emergence of porcine epidemic diarrhea virus in a piglet-producing farm in northwestern Germany in 2019 After initial confirmation of PEDV by real-time RT-PCR, fecal material and small intestine samples from affected pigs were subjected to metagenomic analyses employing next-generation sequencing. Phylogenetic analyses showed high identities among the PEDV sequences obtained from samples of different animals and a close relation to recent strains from Hungary and France. After reports from Asia, that a new PEDV variant caused considerable losses [12, 13] , that highly virulent PEDV variant emerged also in the United States (US) in 2013, with swine farms experiencing explosive epidemics affecting all age classes of animals, with up to 95% mortality in suckling pigs [2, 14] . Emergence of porcine epidemic diarrhea virus in the United States: clinical signs, lesions, and viral genomic sequences abstract: BACKGROUND: Porcine epidemic diarrhea (PED) is a viral enteric disease of pigs. It affects all age classes of animals but lethality is mainly seen in suckling piglets. After its first appearance in England in 1971, Porcine epidemic diarrhea virus (PEDV) has spread worldwide. While sporadic outbreaks prevailed in Europe, the disease had high impact in Asia. Following particularly severe outbreaks in 2011, high impact cases were also reported in the United States and neighboring countries in 2013. Subsequently, outbreaks were also reported in several European countries including Germany. These outbreaks were less severe. This case report describes a recent case of PED re-emergence in Germany and the sequence analyses of the causative PEDV. CASE PRESENTATION: In spring 2019 5 years after re-introduction of PED into Central Europe, a piglet-producer in northwestern Germany experienced an outbreak that affected sows, their suckling piglets, and weaners. After initial confirmation of PEDV by real-time RT-PCR, fecal material and small intestine samples from affected pigs were subjected to metagenomic analyses employing next-generation sequencing. Phylogenetic analyses showed high identities among the PEDV sequences obtained from samples of different animals and a close relation to recent strains from Hungary and France. Compared to the PEDV strains analyzed in 2014, genetic drift could be confirmed. Changes were mainly observed in the spike protein encoding S gene segment. In addition, metagenomic analyses showed multiple Picobirnavirus reads in all investigated samples. CONCLUSION: This case report shows that PEDV is still circulating in Europe. The causative strains are moderately virulent and are still closely related to the so-called INDEL strains reported previously in Europe, including Germany. However, a genetic drift has taken place that can be seen in a novel cluster comprising strains from Germany, Hungary and France in 2019. Relevance and impact of the detected Picobirna sequences need further investigations. url: https://doi.org/10.1186/s12917-020-02548-4 doi: 10.1186/s12917-020-02548-4 id: cord-346250-9kiekksx author: Khare, Sangeeta title: Vaccination with attenuated Salmonella enterica Dublin expressing E coli O157:H7 outer membrane protein Intimin induces transient reduction of fecal shedding of E coli O157:H7 in cattle date: 2010-07-07 words: 5565.0 sentences: 335.0 pages: flesch: 51.0 cache: ./cache/cord-346250-9kiekksx.txt txt: ./txt/cord-346250-9kiekksx.txt summary: title: Vaccination with attenuated Salmonella enterica Dublin expressing E coli O157:H7 outer membrane protein Intimin induces transient reduction of fecal shedding of E coli O157:H7 in cattle The present study was undertaken to test the hypothesis that an adaptive mucosal immune response directed against intimin will reduce or prevent enteric colonization and fecal shedding of E. During the first 28 days, vaccinated calves shed both the vector strain and the intimin-expressing S. Calves challenged with intimin-deficient mutant bacteria do not develop diarrhea or attaching/ effacing lesions, nor are colonized to the same extent as animals infected with wild type or complemented mutant strains [20] . Fecal samples from all the calves were collected daily from day 0 to day 42 post-inoculation to determine the level of vaccine strain shedding. Immunization of cattle with a combination of purified intimin-531, EspA and Tir significantly reduces shedding of Escherichia coli O157:H7 following oral challenge abstract: BACKGROUND: Escherichia coli serogroup O157:H7 has emerged as an important zoonotic bacterial pathogen, causing a range of symptoms from self-limiting bloody diarrhea to severe hemorrhagic colitis and hemolytic-uremic syndrome in humans. Beef and dairy cattle are considered the most important animal reservoirs for this pathogen. One of the important virulence characteristics of E. coli O157:H7 is the eaeA gene encoding the 97 kDa surface protein intimin. Intimin is required for attachment and effacement during the interaction of enterohemorrhagic E. coli with human and bovine neonatal enterocytes. The present study was undertaken to test the hypothesis that an adaptive mucosal immune response directed against intimin will reduce or prevent enteric colonization and fecal shedding of E. coli O157:H7 in cattle. RESULTS: Cattle were orally inoculated with either milk (control), milk with live attenuated Salmonella enterica serovar Dublin (vector), or milk with live attenuated recombinant S. Dublin expressing intimin (vaccinated) on days 0, 14 and 28. On day 98, all calves were challenged orally with E. coli O157:H7 to evaluate whether vaccination with the recombinant S. Dublin expressing intimin would reduce the level of E. coli O157:H7 fecal shedding. During the first 28 days, vaccinated calves shed both the vector strain and the intimin-expressing S. Dublin strain at a similar level. The vector strain was shed for a significantly longer period as compared to the level of recombinant vaccine strain. Calves that received the intimin-expressed vaccine ceased shedding S. Dublin from day 28 to day 63. All calves were challenged with E. coli O157:H7 on day 98 to determine the effect on fecal shedding of E. coli O157:H7. The amount of E. coli O157:H7 in feces was measured for 30 days post-challenge. We observed a transient clearance of E. coli O157:H7 from the feces in the vaccinated calves. The magnitude of fecal E. coli O157:H7 shedding did not correlate with the presence of intimin-specific fecal IgA. CONCLUSION: Oral vaccination with live attenuated recombinant S. Dublin expressing intimin reduced enteric colonization and fecal shedding of E. coli O157:H7. However, the transient clearance of E. coli O157:H7 was not associated with an enhanced IgA-mediated mucosal immune response. url: https://www.ncbi.nlm.nih.gov/pubmed/20609252/ doi: 10.1186/1746-6148-6-35 id: cord-287386-x8uq7499 author: Kongsted, Hanne title: Microbiological, pathological and histological findings in four Danish pig herds affected by a new neonatal diarrhoea syndrome date: 2013-10-12 words: 4484.0 sentences: 248.0 pages: flesch: 49.0 cache: ./cache/cord-287386-x8uq7499.txt txt: ./txt/cord-287386-x8uq7499.txt summary: CONCLUSIONS: The results of the study supported the hypothesis that a new neonatal porcine diarrhoea was present in the investigated herds, since no known pathogen(s) or management factors could explain the diarrhoeal outbreaks. Based on the findings in the four herds the following case-definition of NNPDS was suggested: Non-haemorrhagic diarrhoea during the first week of life, without detection of known infectious pathogens, characterized by milk-filled stomachs and flaccid intestines at necropsy. The article describes the prevalence of well-known enteric pathogens in age-matched diarrhoeic-and nondiarrhoeic piglets from four herds affected by neonatal diarrhoea with no previously established laboratory conclusion. Herds were recommended by veterinary practitioners and included in accordance with the following criteria: 1) Presence of diarrhoea responding poorly to antibiotics during the first week of life (at least 30% affected litters for a period of minimum 6 months), 2) Routine vaccination of sows against ETEC and CPC, 3) Failure of preventive management interventions, 4) PRRS negative farrowing unit as demonstrated in blood samples tested by ELISA/IPT or PCR and 5) Negative results of routine diagnostic examinations for ETEC, CPC and RV in five diarrhoeic piglets aged one to four days. abstract: BACKGROUND: Neonatal diarrhoea is a frequent clinical condition in commercial swine herds, previously regarded to be uncomplicated to treat. However, since 2008 it seems that a new neonatal diarrhoeic syndrome unresponsive to antibiotics and common management practices has emerged. Routine laboratory examinations have not detected any pathogen related to this syndrome. The primary purpose of this study was to evaluate if well-known enteric pathogens could be associated with outbreaks of neonatal diarrhoea, thus question the hypotheses of a new syndrome. Furthermore, we wanted to evaluate macroscopic and microscopic findings associated with these outbreaks and if possible propose a preliminary piglet-level case-definition on syndrome New Neonatal Porcine Diarrhoea syndrome (NNPDS). RESULTS: Four well-managed herds experiencing neonatal diarrhoea with no previously established laboratory conclusion and suspected to suffer from New Neonatal Porcine Diarrhoea Syndrome, were selected. Within these herds, 51 diarrhoeic and 50 non-diarrhoeic piglets at the age of three to seven days were necropsied and subjected to histological and microbiological examination. Faeces were non-haemorrhagic. Neither enterotoxigenic E. coli, Clostridium perfringens type A or C, Clostridium difficile, rotavirus, coronavirus, Cryptosporidium spp, Giardia spp, Cystoisospora suis nor Strongyloides ransomi were associated with diarrhoea in the investigated outbreaks. Macroscopically, the diarrhoeic piglets were characterized by filled stomachs and flaccid intestines without mucosal changes. The predominant histological lesions were villous atrophy in jejunum and ileum. Epithelial lesions in colon were seen in one third of the case piglets. CONCLUSIONS: The results of the study supported the hypothesis that a new neonatal porcine diarrhoea was present in the investigated herds, since no known pathogen(s) or management factors could explain the diarrhoeal outbreaks. Based on the findings in the four herds the following case-definition of NNPDS was suggested: Non-haemorrhagic diarrhoea during the first week of life, without detection of known infectious pathogens, characterized by milk-filled stomachs and flaccid intestines at necropsy. url: https://www.ncbi.nlm.nih.gov/pubmed/24119974/ doi: 10.1186/1746-6148-9-206 id: cord-297057-qhc8b5x1 author: Kylie, Jennifer title: Comparison of the fecal microbiota of domestic commercial meat, laboratory, companion, and shelter rabbits (Oryctolagus cuniculi) date: 2018-04-27 words: 6895.0 sentences: 306.0 pages: flesch: 40.0 cache: ./cache/cord-297057-qhc8b5x1.txt txt: ./txt/cord-297057-qhc8b5x1.txt summary: The objectives of this study were to describe the fecal microbiota of domestic rabbits from a variety of settings (commercial meat, companion, laboratory, and shelter) and to identify how factors such as age, season, and routine antimicrobial use affect the fecal microbiota composition. Significant differences in composition were noted between commercial, companion, laboratory, and shelter rabbit samples for proportions of Verrucomicrobia (P < 0.01), Proteobacteria (P < 0.01), and Lentisphaerae (P = 0.01) within the total microbiota. Significant differences (p ≤ 0.05) are present between sources for Proteobacteria, Verrucomicrobia, and Lentisphaera (included in ''Other'' and composed < 1% of the total composition) difference between the fecal microbiota community structure of does and fryers was only noted using the Yue and Clayton tree with the parsimony test (P = 0.04); however, no more than five samples were noted to be clustered by age within commercial meat samples in the Yue and Clayton tree analysis (Fig. 3) . abstract: BACKGROUND: Rabbits are cecotrophic, hindgut-fermenters that rely heavily on their gastrointestinal microbiota for optimal digestion of plant-based diets. Dysbiosis, caused by disruption of the gastrointestinal microbiota, is known to predispose rabbits to rabbit enteritis complex (REC), a major cause of morbidity and mortality. The objectives of this study were to describe the fecal microbiota of domestic rabbits from a variety of settings (commercial meat, companion, laboratory, and shelter) and to identify how factors such as age, season, and routine antimicrobial use affect the fecal microbiota composition. RESULTS: A total of 86 pooled commercial meat, 54 companion, 14 pooled laboratory, and 14 shelter rabbit fecal samples were evaluated using 16S rRNA gene sequencing of the V4 region. In all sample types, the predominant bacterial phylum was Firmicutes. Other commonly identified phyla (composing ≥ 1% of the total microbiota composition) were Verrucomicrobia, Proteobacteria, and Bacteroidetes. Significant differences in composition were noted between commercial, companion, laboratory, and shelter rabbit samples for proportions of Verrucomicrobia (P < 0.01), Proteobacteria (P < 0.01), and Lentisphaerae (P = 0.01) within the total microbiota. Within the commercial meat rabbit samples, significant differences between the microbiota composition of growers (n = 42) and does (n = 44) were limited to one unclassified Firmicutes (P = 0.03) and no differences were identified at the phylum level. Significant differences were present between fecal samples taken from rabbits during the summer (n = 44) compared to the winter (n = 42), with Firmicutes (P = 0.04), Verrucomicrobia (P = 0.03), Proteobacteria (P = 0.02), Deinococcus-Thermus (P = 0.04), Armatimonadates (P = 0.003), and Actinobacteria (P = 0.03) forming significantly different proportions of the microbiota. The only significant difference in composition between those farms that routinely reported antimicrobial use and those that did not was in one unclassified Bacteroidetes (P < 0.05) and no differences were identified at the phylum level. CONCLUSIONS: Rabbit husbandry and diet, in addition to season, significantly influence the fecal microbiota composition of domestic rabbits, while age of the rabbit post-weaning has minimal impact.

Choleraesuis) vaccine vector could be used to deliver heterologous antigens to prevent and control pig diseases. We have previously shown that a live-attenuated S. Choleraesuis vaccine candidate strain rSC0011 (ΔP(crp527)::TT araC P(BAD)crp Δpmi-2426 ΔrelA199::araC P(BAD)lacI TT ΔasdA33, Δ, deletion, TT, terminator) delivering SaoA, a conserved surface protein in most of S. suis serotypes, provided excellent protection against S. suis challenge, but occasionally lead to morbidity (enteritidis) in vaccinated mice (approximately 1 in every 10 mice). Thus, alternated attenuation method was sought to reduce the reactogenicity of strain rSC0011. Herein, we described another recombinant attenuated S. Choleraesuis vector, rSC0012 (ΔP(fur88):: TT araC P(BAD)fur Δpmi-2426 ΔrelA199:: araC P(BAD)lacI TT ΔasdA33) with regulated delayed fur mutation to avoid inducing disease symptoms while exhibiting a high degree of immunogenicity. RESULTS: The strain rSC0012 strain with the ΔP(fur88)::TT araC P(BAD)fur mutation induced less production of inflammatory cytokines than strain rSC0011 with the ΔP(crp527)::TT araC P(BAD)crp mutation in mice. When delivering the same pS-SaoA plasmid, the intraperitoneal LD(50) of rSC0012 was 18.2 times higher than that of rSC0011 in 3-week-old BALB/C mice. rSC0012 with either pS-SaoA or pYA3493 was cleared from spleen and liver tissues 7 days earlier than rSC0011 with same vectors after oral inoculation. The strain rSC0012 synthesizing SaoA induced high titers of anti-SaoA antibodies in both systemic (IgG in serum) and mucosal (IgA in vaginal washes) sites, as well as increased level of IL-4, the facilitator of Th2-type T cell immune response in mice. The recombinant vaccine rSC0012(pS-SaoA) conferred high percentage of protection against S. suis or S. Choleraesuis challenge in BALB/C mice. CONCLUSIONS: The live-attenuated Salmonella enterica serotype Choleraesuis vaccine rSC0012(pS-SaoA) with regulated delayed fur mutation provides a foundation for the development of a safe and effective vaccine against S. Choleraesuis and S. suis. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7203871/ doi: 10.1186/s12917-020-02340-4 id: cord-001134-8ljgxnhf author: Lin, Chao-Nan title: Comparison of viremia of type II porcine reproductive and respiratory syndrome virus in naturally infected pigs by zip nucleic acid probe-based real-time PCR date: 2013-09-12 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Porcine reproductive and respiratory syndrome virus (PRRSV) is a RNA virus with high genetic variation. This virus causes significant economic losses in most pig-producing countries. The clinical presentation of PRRSV ranges from asymptomatic to devastating. In this study, we developed a sensitive and specific zip nucleic acid probe-based real-time PCR assay to evaluate the viremia of natural PRRSV-infected pigs in Taiwan. Serum samples were collected from 577 pigs aged 5–12 weeks. These include 444 clinically healthy pigs and 133 symptomatic pigs were confirmed to have porcine respiratory disease complex (PRDC). RESULTS: Viremia was quantified in 79 of the 444 (17.8%) clinically healthy pigs and in 112 of the 133 (84.2%) PRDC cases. Viremias were significantly more common in pigs with PRDC compared with the clinically healthy pigs (P <0.0001). These results suggest that a high viral load is a major feature of PRRSV-affected pigs. CONCLUSIONS: ZNA probe-based real-time PCR can be a useful tool to diagnose symptomatic and asymptomatic PRRSV-infected pigs. The presence of this marker in a sample of animals with high PRRSV loads (>10(4.2) PRRSV genomes/μl of serum) seems to indicate that it correlates with the presence of PRDC in pigs. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3847877/ doi: 10.1186/1746-6148-9-181 id: cord-344309-6c2wttxg author: Lin, Huixing title: Development and application of an indirect ELISA for the detection of antibodies to porcine epidemic diarrhea virus based on a recombinant spike protein date: 2018-08-20 words: 4411.0 sentences: 221.0 pages: flesch: 55.0 cache: ./cache/cord-344309-6c2wttxg.txt txt: ./txt/cord-344309-6c2wttxg.txt summary: title: Development and application of an indirect ELISA for the detection of antibodies to porcine epidemic diarrhea virus based on a recombinant spike protein In this study, an indirect enzyme-linked immunosorbent assay (ELISA) based on the recombinant truncated spike (S) protein of PEDV was developed and validated.

Therefore, this study selected a gene fragment within the S1 subunit as a coating antigen to develop an indirect enzyme-linked immunosorbent assay (ELISA) method for the detection of PEDV antibodies. Detection of antibodies against porcine epidemic diarrhea virus in serum and colostrum by indirect ELISA abstract: BACKGROUND: As the major causative agent of swine viral diarrhea, porcine epidemic diarrhea virus (PEDV) has caused massive losses to the economies of swine raising countries. Accordingly, the serological detection of corresponding antibodies would be beneficial to diagnose PEDV indirectly to control the disease. In this study, an indirect enzyme-linked immunosorbent assay (ELISA) based on the recombinant truncated spike (S) protein of PEDV was developed and validated. RESULTS: The reaction conditions of the developed indirect ELISA were optimized. This indirect ELISA was compared to indirect immunoinfluscent assay (IFA), and the overall coincidence rate was 96.74% based on testing 368 clinical serum samples with different PEDV antibody levels. No cross-reactivity with other common swine pathogens was detected for the developed S1 indirect ELISA. Finally, the S1 indirect ELISA was applied to detect serum antibodies of 3304 field samples collected from different pig farms in eastern China, and it presented an overall substantial agreement on the PEDV infection status. CONCLUSIONS: This established S1 indirect ELISA is capable of detecting serum antibodies against PEDV, and due to its high sensitivity and specificity, it could be applied for serological evaluation and indirect diagnosis of PEDV infection. url: https://doi.org/10.1186/s12917-018-1570-5 doi: 10.1186/s12917-018-1570-5 id: cord-253308-wgseqk4t author: Liu, Chang title: PCV cap proteins fused with calreticulin expressed into polymers in Escherichia coli with high immunogenicity in mice date: 2020-08-27 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Porcine circovirus type 2 (PCV2) is the main causative agent of porcine circovirus diseases (PCVDs) which causes huge yearly economic losses in the swine industry. Capsid protein (Cap) is the major structural protein of PCV2 that can induce a protective immune response. Therefore, developing a novel and safe subunit vaccine against PCV2 infection is needed. RESULTS: In this study, the Cap gene was bound to the truncated calreticulin (CRT) (120–250 aa/120–308 aa) at the N/C terminal, and then the CRT-Cap fusion genes were expressed in Escherichia coli (E.coli). The size-exclusion chromatography and dynamic light scattering (DLS) data showed that the purified recombinant CRT-Cap fusion protein (rP5F) existed in the form of polymers. Immunization with rP5F stimulated high levels of PCV2 specific antibody and neutralization antibody in mice, which were almost identical to those induced by the commercial subunit and inactivated vaccines. The lymphocyte proliferation and cytokine secretion were also detected in rP5F immunized mice. According to the results of PCV2-challenge experiment, the virus loads significantly decreased in mice immunized with rP5F. The data obtained in the current study revealed that rP5F had the potential to be a subunit vaccine candidate against PCV2 in the future. CONCLUSIONS: We have successfully expressed Cap-CRT fusion proteins in E.coli and optimized rP5F could form into immunogenic polymers. Mice immunized with rP5F efficiently induced humoral and part of cellular immune responses and decreased the virus content against PCV2-challenge, which suggested that rF5P could be a potential subunit vaccine candidate. url: https://doi.org/10.1186/s12917-020-02527-9 doi: 10.1186/s12917-020-02527-9 id: cord-343165-la5sy0vq author: Liu, Chuanmin title: Nitric oxide-generating compound GSNO suppresses porcine circovirus type 2 infection in vitro and in vivo date: 2017-02-21 words: 4857.0 sentences: 256.0 pages: flesch: 56.0 cache: ./cache/cord-343165-la5sy0vq.txt txt: ./txt/cord-343165-la5sy0vq.txt summary: This study was conducted to investigate the antiviral activity of NO generated from S-nitrosoglutathione (GSNO), during PCV2 infection of PK-15 cells and BALB/c mice. NO strongly inhibited PCV2 replication in PK-15 cells, and the antiviral effect was reversed by Hb. An in vivo assay indicated that GSNO treatment reduced the progression of PCV2 infection in mice, evident as reductions in the percentages of PCV2-positive sera and tissue samples and in the viral DNA copies in serum samples. CONCLUSIONS: Our data demonstrate that the NO-generating compound GSNO suppresses PCV2 infection in PK-15 cells and BALB/c mice, indicating that NO and its donor, GSNO, have potential value as antiviral drugs against PCV2 infection. The antiviral activity of GSNO was determined from the appearance of PCV2-infected cells, viral titers, and PCV2 DNA copy numbers. In this study, we verified the antiviral activity of the NOgenerating compound GSNO during PCV2 infection in PK-15 cells and BALB/c mice. abstract: BACKGROUND: Nitric oxide (NO), an important signaling molecule with biological functions, has antimicrobial activity against a variety of pathogens including viruses. To our knowledge, little information is available about the regulatory effect of NO on porcine circovirus type 2 (PCV2) infection. This study was conducted to investigate the antiviral activity of NO generated from S-nitrosoglutathione (GSNO), during PCV2 infection of PK-15 cells and BALB/c mice. RESULTS: GSNO released considerable NO in the culture medium of PK-15 cells, and NO was scavenged by its scavenger hemoglobin (Hb) in a dose-dependent manner. NO strongly inhibited PCV2 replication in PK-15 cells, and the antiviral effect was reversed by Hb. An in vivo assay indicated that GSNO treatment reduced the progression of PCV2 infection in mice, evident as reductions in the percentages of PCV2-positive sera and tissue samples and in the viral DNA copies in serum samples. GSNO also improved the growth performance and immune organs (spleens and thymuses) of the PCV2-infected mice to some degree. CONCLUSIONS: Our data demonstrate that the NO-generating compound GSNO suppresses PCV2 infection in PK-15 cells and BALB/c mice, indicating that NO and its donor, GSNO, have potential value as antiviral drugs against PCV2 infection. url: https://www.ncbi.nlm.nih.gov/pubmed/28222773/ doi: 10.1186/s12917-017-0976-9 id: cord-275512-7yik78yc author: Lojkić, Ivana title: Detection and molecular characterisation of bovine corona and toroviruses from Croatian cattle date: 2015-08-13 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Bovine coronavirus (BCoV) together with bovine torovirus (BToV), both members of the Coronaviridae family, order Nidovirales are the most common viral enteric pathogens. Although studied separately, their joint occurrence and the molecular diversity in cattle in Croatia have not been investigated. METHODS: A survey is carried out on 101 fecal samples from diarrheic young and adult cattle during the 3-year period from i) one large dairy herd, ii) four small herds and iii) three nasal and paired fecal samples from calves with symptoms of respiratory disease. Samples were submitted to RT-PCR and sequencing for BCoV Nucleocapsid gene, BCoV Spike gene and BToV Spike gene. RESULTS: BCoV was detected in 78.8 % of fecal samples from symptomatic cattle and three nasal and paired fecal samples from calves with respiratory symptoms. BToV was detected in 43.2 % of fecal samples from symptomatic cattle and a fecal sample from calves with respiratory symptoms. Molecular characterisation of those viruses revealed some nucleotide and aminoacid differences in relation to reference strains. CONCLUSIONS: BToV should be regarded as a relevant pathogen for cattle that plays a synergistic role in mixed enteric infections. url: https://www.ncbi.nlm.nih.gov/pubmed/26268320/ doi: 10.1186/s12917-015-0511-9 id: cord-345516-fgn7rps3 author: Miller, Laura C title: Analysis of the swine tracheobronchial lymph node transcriptomic response to infection with a Chinese highly pathogenic strain of porcine reproductive and respiratory syndrome virus date: 2012-10-30 words: 4730.0 sentences: 204.0 pages: flesch: 43.0 cache: ./cache/cord-345516-fgn7rps3.txt txt: ./txt/cord-345516-fgn7rps3.txt summary: title: Analysis of the swine tracheobronchial lymph node transcriptomic response to infection with a Chinese highly pathogenic strain of porcine reproductive and respiratory syndrome virus Emergence in 2006 of a novel highly pathogenic PRRSV (HP-PRRSV) isolate in China necessitated a comparative investigation into the host transcriptome response in tracheobronchial lymph nodes (TBLN) 13 days post-infection with HP-PRRSV rJXwn06, PRRSV strain VR-2332 or sham inocula. Gene IDs and log2 fold-change expression values for significant hits, that had FPKM values in both the control and the infected differential expression testing for transcripts (Cuffdiff output files), were then analyzed using the Ingenuity Pathway Analysis software. abstract: BACKGROUND: Porcine reproductive and respiratory syndrome virus (PRRSV) is a major pathogen of swine worldwide. Emergence in 2006 of a novel highly pathogenic PRRSV (HP-PRRSV) isolate in China necessitated a comparative investigation into the host transcriptome response in tracheobronchial lymph nodes (TBLN) 13 days post-infection with HP-PRRSV rJXwn06, PRRSV strain VR-2332 or sham inocula. RNA from each was prepared for next-generation sequencing. Amplified library constructs were directly sequenced and a list of sequence transcripts and counts was generated using an RNAseq analysis pipeline to determine differential gene expression. Transcripts were annotated and relative abundance was calculated based upon the number of times a given transcript was represented in the library. RESULTS: Major changes in transcript abundance occurred in response to infection with either PRRSV strain, each with over 630 differentially expressed transcripts. The largest increase in transcript level for either virus versus sham-inoculated controls were three serum amyloid A2 acute-phase isoforms. However, the degree of up or down-regulation of transcripts following infection with HP-PRRSV rJXwn06 was greater than transcript changes observed with US PRRSV VR-2332. Also, of 632 significantly altered transcripts within the HP-PRRSV rJXwn06 library 55 were up-regulated and 69 were down-regulated more than 3-fold, whilst in the US PRRSV VR-2332 library only 4 transcripts were up-regulated and 116 were down-regulated more than 3-fold. CONCLUSIONS: The magnitude of differentially expressed gene profiles detected in HP-PRRSV rJXwn06 infected pigs as compared to VR-2332 infected pigs was consistent with the increased pathogenicity of the HP-PRRSV in vivo. url: https://doi.org/10.1186/1746-6148-8-208 doi: 10.1186/1746-6148-8-208 id: cord-268210-gvhjwqe7 author: Nöremark, Maria title: A survey of visitors on Swedish livestock farms with reference to the spread of animal diseases date: 2013-09-16 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: In addition to livestock movements, other between-farm contacts such as visitors may contribute to the spread of contagious animal diseases. Knowledge about such contacts is essential for contingency planning. Preventive measures, risk-based surveillance and contact tracing may be facilitated if the frequency and type of between-farm contacts can be assessed for different types of farms. The aim of this study was to investigate the frequency and types of visitors on farms with cloven-hoofed animals in Sweden and to analyse whether there were differences in the number of visitors attributable to region, season, and type of herd. Data were collected from Swedish farmers through contact-logs covering two-week periods during four different seasons. RESULTS: In total, 482 (32%) farmers filled in the contact log for at least one period and the data represent 18,416 days. The average number of professional and non-professional visitors per day was 0.3 and 0.8, respectively. Whereas the number of professional visitors seemed to increase with increasing herd size, this relation was not seen for non-professional visits. The mean numbers of visitors per day were highest in the summer and in the farm category ‘small mixed farm’. Reports of the visitors’ degree of contact with the animals showed that veterinarians, AI-technicians, animal transporters and neighbours were often in direct contact with the animals or entered the stables and 8.8% of the repairmen were also in direct contact with animals, which was unexpected. In a multivariable analysis, species, herd size and season were significantly associated with the number of professional visitors as well as the number of visitors in direct contact with the animals. CONCLUSION: In conclusion there was a large variation between farms in the number and type of contacts. The number of visitors that may be more likely to spread diseases between farms was associated with animal species and herd size. url: https://www.ncbi.nlm.nih.gov/pubmed/24040830/ doi: 10.1186/1746-6148-9-184 id: cord-301175-6alsigxk author: Okda, Faten title: Development of an indirect ELISA, blocking ELISA, fluorescent microsphere immunoassay and fluorescent focus neutralization assay for serologic evaluation of exposure to North American strains of Porcine Epidemic Diarrhea Virus date: 2015-08-01 words: 8275.0 sentences: 411.0 pages: flesch: 46.0 cache: ./cache/cord-301175-6alsigxk.txt txt: ./txt/cord-301175-6alsigxk.txt summary: title: Development of an indirect ELISA, blocking ELISA, fluorescent microsphere immunoassay and fluorescent focus neutralization assay for serologic evaluation of exposure to North American strains of Porcine Epidemic Diarrhea Virus Therefore, the objective of this study was to develop and validate multiple improved serological assays for PEDV, including an indirect ELISA (iELISA); a highly specific monoclonal antibody-based blocking ELISA (bELISA); fluorescent microsphere immunoassays (FMIA) that can be multiplexed to monitor exposure to multiple antigens and pathogens simultaneously; and a fluorescent focus neutralization assay (FFN) to measure functional virus neutralizing antibodies. RESULTS: A recombinant North American nucleoprotein (NP) based iELISA was developed and validated along with a bELISA using newly developed PEDV-NP specific biotinylated monoclonal antibodies (mAbs) and an FMIA using magnetic beads coupled with expressed NA PEDV-NP. In this study, we report the adaptation of a recombinant, highly purified, NA PEDV-NP antigen to the development of iELISA, bELISA and FMIA platforms for the detection of PEDV antibodies in serum. abstract: BACKGROUND: Recent, severe outbreaks of porcine epidemic diarrhea virus (PEDV) in Asia and North America highlight the need for well-validated diagnostic tests for the identification of PEDV infected animals and evaluation of their immune status to this virus. PEDV was first detected in the U.S. in May 2013 and spread rapidly across the country. Some serological assays for PEDV have been previously described, but few were readily available in the U.S. Several U.S. laboratories quickly developed indirect fluorescent antibody (IFA) assays for the detection of antibodies to PEDV in swine serum, indicating prior exposure. However, the IFA has several disadvantages, including low throughput and relatively subjective interpretation. Different serologic test formats have advantages and disadvantages, depending on the questions being asked, so a full repertoire of tests is useful. Therefore, the objective of this study was to develop and validate multiple improved serological assays for PEDV, including an indirect ELISA (iELISA); a highly specific monoclonal antibody-based blocking ELISA (bELISA); fluorescent microsphere immunoassays (FMIA) that can be multiplexed to monitor exposure to multiple antigens and pathogens simultaneously; and a fluorescent focus neutralization assay (FFN) to measure functional virus neutralizing antibodies. RESULTS: A recombinant North American nucleoprotein (NP) based iELISA was developed and validated along with a bELISA using newly developed PEDV-NP specific biotinylated monoclonal antibodies (mAbs) and an FMIA using magnetic beads coupled with expressed NA PEDV-NP. Receiver operating characteristic (ROC) analysis was performed using swine serum samples (iELISA n = 1486, bELISA n = 1186, FMIA n = 1420). The ROC analysis for the FMIA showed estimated sensitivity and specificity of 98.2 and 99.2 %, respectively. The iELISA and bELISA showed a sensitivity and specificity of 97.9 and 97.6 %; and 98.2 and 98.9 %, respectively. Inter-rater (kappa) agreement was calculated to be 0.941 between iELISA and IFA, 0.945 between bELISA and IFA and 0.932 between FMIA and IFA. Similar comparative kappa values were observed between the iELISA, bELISA and FMIA, which demonstrated a significant level of testing agreement among the three assays. No cross-reactivity with the closely related coronaviruses, transmissible gastroenteritis virus (TGEV) or porcine respiratory coronavirus (PRCV) was noted with these assays. All three assays detected seroconversion of naïve animals within 6–9 days post exposure. The FFN assay allows relative quantitation of functional neutralizing antibodies in serum, milk or colostrum samples. CONCLUSION: Well-validated iELISA, bELISA and FMIA assays for the detection of PEDV antibodies were developed and showed good correlation with IFA and each other. Each assay format has advantages that dictate how they will be used in the field. Newly developed mAbs to the PEDV-NP were used in the bELISA and for expediting FFN testing in the detection and quantitation of neutralizing antibodies. In addition, these PEDV mAbs are useful for immunohistochemistry, fluorescent antibody staining and other antigen-based tests. Measurement of neutralizing antibody responses using the FFN assay may provide a valuable tool for assessment of vaccine candidates or protective immunity. url: https://doi.org/10.1186/s12917-015-0500-z doi: 10.1186/s12917-015-0500-z id: cord-346685-kldpmws7 author: Pan, Qing title: Co-infection of broilers with Ornithobacterium rhinotracheale and H9N2 avian influenza virus date: 2012-07-02 words: 3814.0 sentences: 219.0 pages: flesch: 54.0 cache: ./cache/cord-346685-kldpmws7.txt txt: ./txt/cord-346685-kldpmws7.txt summary: Typical pneumonia and airsacculitis were observed both in broilers inoculated intraperitoneally with an ORT isolate alone and in those co-infected with ORT and H9N2 virus isolates. In the current report, we present the characterisation of ORT and H9N2 isolates obtained from co-infected broilers, with the objective of understanding the aetiology of severe avian pneumonia. Broilers inoculated intraperitoneally with ORT/chicken/Shandong/2011 alone displayed pneumonia and typical airsacculitis, and coinfection of the broilers with ORT and H9N2 virus isolates induced higher mortality than infection with ORT or H9N2 virus alone. The results of this study strongly suggest that co-infection with ORT and H9N2 virus is responsible for the current severe pneumonia with high mortality in broilers of China. However, the birds infected with the ORT isolated in this study had a 50% mortality rate, and a co-infection with the H9N2 virus resulted in 70% death. Co-infection of broilers with Ornithobacterium rhinotracheale and H9N2 avian influenza virus abstract: BACKGROUND: Since 2008, a progressive pneumonia has become prevalent in broilers and laying hens. This disease occurrs the first day after hatching and lasts more than 30 days, resulting in approximately 70% morbidity and 30% mortality in broilers. The objective of this study was to isolate and identify the pathogens that are responsible for the progressive pneumonia and establish an animal model for drug screening. RESULTS: 193 serum samples were collected from 8 intensive farms from 5 provinces in China and analysed in the current research. Our clinical survey showed that 65.2% to 100% of breeding broilers, breeding layers, broilers and laying hens were seropositive for ORT antibodies. From 8 intensive farms, six ORT isolates were identified by PCR and biochemical assays, and two H9N2 viruses were isolated. Newcastle Disease Virus (NDV) and Infectious BronchitisVirus (IBV) were excluded. Typical pneumonia and airsacculitis were observed both in broilers inoculated intraperitoneally with an ORT isolate alone and in those co-infected with ORT and H9N2 virus isolates. Specifically, the survival rate was 30%, 20%, 70%, 50% and 90% in birds inoculated with ORT+H9N2 virus, ORT followed by H9N2 virus, H9N2 virus followed by ORT, and ORT or H9N2 virus alone, respectively. CONCLUSIONS: The results of this study suggest that ORT infections of domestic poultry have been occurring frequently in China. ORT infection can induce higher economic losses and mortality if H9N2 AIV is also present. Although the isolation of ORT and H9N2 virus has been reported previously, there have been no reported co-infections of poultry with these two pathogens. This is the first report of co-infection of broilers with ORT and H9N2 virus, and this co-infection is probably associated with the outbreak of broiler airsacculitis in China, which has caused extensive economic losses. url: https://www.ncbi.nlm.nih.gov/pubmed/22748160/ doi: 10.1186/1746-6148-8-104 id: cord-303012-qbkkhfcb author: Paris, Jasmin K title: Enteropathogen co-infection in UK cats with diarrhoea date: 2014-01-12 words: 6221.0 sentences: 410.0 pages: flesch: 54.0 cache: ./cache/cord-303012-qbkkhfcb.txt txt: ./txt/cord-303012-qbkkhfcb.txt summary: We studied enteropathogen co-infection in diarrhoeic UK cats using results of a real time PCR assay for 8 enteropathogenic species; feline coronavirus (Co), feline panleukopenia virus (Pa), Clostridium perfringens (Cl), Salmonella enterica (Sa), Giardia spp. The primary objective of this study was therefore to identify and describe feline enteropathogen co-infection in a large population of diarrhoeic UK cats using the results obtained from the same PCR assay used in [12] for a panel of 8 enteropathogens (feline coronavirus, feline panleukopenia virus, Clostridium perfringens, Salmonella enterica, Giardia spp., T. Target genes for enteropathogen detection using real-time PCR were as follows: feline coronavirus 7b gene (DQ010921.1), feline panleukopenia virus VP2 gene (EU252145), Clostridium perfringens alpha toxin gene (AM888388), Salmonella enterica invasion A gene (EU348366), Giardia smallsubunit rRNA gene (DQ836339), Tritrichomonas foetus 5.8S rRNA gene (AF339736), Cryptosporidium smallsubunit rRNA gene (A093489), and Toxoplasma gondii internal transcribed spacer-1 gene (L49390). abstract: BACKGROUND: Individual enteropathogen infections in healthy and clinically ill cats are well described, but prevalence and patterns of enteropathogen co-infection have only been reported on a limited basis. We studied enteropathogen co-infection in diarrhoeic UK cats using results of a real time PCR assay for 8 enteropathogenic species; feline coronavirus (Co), feline panleukopenia virus (Pa), Clostridium perfringens (Cl), Salmonella enterica (Sa), Giardia spp. (Gi), Tritrichomonas foetus (Tr), Cryptosporidium spp. (Cr), and Toxoplasma gondii (To). Age, gender, breed and history were recorded. PCR panels from 1088 diarrhoeic cats were available for analysis. RESULTS: Overall enteropathogen prevalence was 56.9% (Co), 22.1% (Pa), 56.6% (Cl), 0.8% (Sa), 20.6% (Gi), 18.8% (Tr), 24.4% (Cr) and 1.0% (To). Prevalence of Co, Gi and Tr was higher in pedigree cats compared to non-pedigree cats (DSH) and prevalence decreased with increasing age for Co, Pa, Gi, Cr and Tr. Co-infection was common: ≥2 enteropathogens were detected in 62.5% of cats, and 13.3% of cats had ≥4 enteropathogens. Mean ( [Formula: see text]) enteropathogen co-infection 2.01 (±1.3 SD), was significantly higher in pedigree cats ( [Formula: see text] =2.51) compared to DSH ( [Formula: see text] =1.68) and decreased with age ( [Formula: see text] =2.64 <6 months, [Formula: see text] =1.68 for >1 yr). More cats were negative for all 8 enteropathogens tested (12.7%) than expected. When exact combinations of co-infection were examined, Tr tended to be found in combinations with Co, Cl, and Gi. CONCLUSIONS: Multiple infections should be considered the most likely result of faecal testing in cats, and case management needs to take this into account. In contrast, the relatively high percentage of cats negative for all 8 enteropathogens tested could indicate an innate resistance to infection. Alternatively it could indicate a lack of exposure to these 8 enteropathogens or the presence of other enteropathogens not assessed by this assay. url: https://www.ncbi.nlm.nih.gov/pubmed/24410914/ doi: 10.1186/1746-6148-10-13 id: cord-355991-4zu69e0y author: Piñeyro, Pablo Enrique title: First retrospective studies with etiological confirmation of porcine transmissible gastroenteritis virus infection in Argentina date: 2018-09-24 words: 3913.0 sentences: 221.0 pages: flesch: 44.0 cache: ./cache/cord-355991-4zu69e0y.txt txt: ./txt/cord-355991-4zu69e0y.txt summary: The epidemiological and clinical presentations of outbreaks of neonatal mortality associated with enteritis and the detection of TGEV started in the gestation units. When TGEV enters in a naïve herds, an epizootic form characterized by a 100% mortality of pre-weaning piglets due to diarrhea and dehydration is normally observed [1, 14] . In this study, although all cases were selected using clinical features and epidemiological information, the histological evaluation consistently showed lesions compatible with viral infection. The application of IHC and ISH-RNA on archived paraffin blocks from cases of neonatal diarrhea with high morbidity and mortality allowed retrospective identification of TGEV infection. During the period when the sows showed gastro-enteric clinical signs, 2-to 4-day-old piglets presented vomiting (75-80%) and diarrhea (90%), and the mortality rate of suckling pigs reached 90%. Emergence of porcine epidemic diarrhea virus in the United States: clinical signs, lesions, and viral genomic sequences abstract: BACKGROUND: In 2014, a notification of porcine transmissible gastroenteritis virus (TGEV) was made by the National Services of Animal Health of Argentina (SENASA) to the World Organization of Animal Health (OIE). The notification was based on a serological diagnosis in a small farm with a morbidity rate of 2.3% without enteric clinical signs. In order to determine if TGEV was circulating before the official report, a retrospective study on cases of neonatal diarrhea was performed. The selection criteria was a sudden increase in mortality in 1- to 21-day-old piglets with watery diarrhea that did not respond to antibiotics. Based on these criteria, three clinical cases were identified during 2010–2015. RESULTS: All animals that were evaluated presented histological lesions consistent with enteric viral infection. The feces and ultrathin sections of intestine that were evaluated by electron microscopy confirmed the presence of round particles of approximately 80 nm in size and characterized by finely granular electrodense nucleoids consistent with complete particles of coronavirus. The presence of the TGEV antigen was confirmed by monoclonal specific immunohistochemistry, and final confirmation of a metabolically-active virus was performed by in situ hybridization to detect a TGE mRNA encoding spike protein. All sections evaluated in this case were negative for PEDV and rotavirus A. CONCLUSIONS: This is the first case series describing neonatal mortality with etiological confirmation of TGEV in Argentina. The clinical diagnosis of TGEV infections in endemic regions is challenging due to the epidemiological distribution and coinfection with other enteric pathogens that mask the clinical presentation.

Swine influenza is generally characterized by acute onset of fever and respiratory symptoms. The most frequent complications of influenza are secondary bacterial pneumonia. The objective of this work was to study the acute phase proteins (APP) responses after coinfection of piglets with H1N1 swine influenza virus (SwH1N1) and Pasteurella multocida (Pm) in order to identify whether the individual APP response correlate with disease severity and whether APP could be used as markers of the health status of coinfected pigs. RESULTS: In all coinfected pigs clinical sings, including fever, coughing and dyspnea, were seen. Viral shedding was observed from 2 to 7 dpi. The mean level of antibodies against Pm dermonecrotoxin in infected piglets increase significantly from 7 dpi. Anti-SwH1N1 antibodies in the serum were detected from 7 dpi. The concentration of C-reactive protein (CRP) increased significantly at 1 dpi as compared to control pigs, and remained significantly higher to 3 dpi. Level of serum amyloid A (SAA) was significantly higher from 2 to 3 dpi. Haptoglobin (Hp) was significantly elevated from 3 dpi to the end of study, while pig major acute phase protein (Pig-MAP) from 3 to 7 dpi. The concentrations of CRP, Hp and SAA significantly increased before specific antibodies were detected. Positive correlations were found between serum concentration of Hp and SAA and lung scores, and between clinical score and concentrations of Pig-MAP and SAA. CONCLUSIONS: The results of current study confirmed that monitoring of APP may revealed ongoing infection, and in this way may be useful in selecting clinically healthy pigs (i.e. before integration into an uninfected herd). Present results corroborated our previous findings that SAA could be a potentially useful indicator in experimental infection studies (e.g. vaccine efficiency investigations) or as a marker for disease severity, because of correlation observed between its concentration in serum and disease severity (lung scores, clinical scores). url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3554491/ doi: 10.1186/1746-6148-9-14 id: cord-326770-yoefyowv author: Sayama, Yusuke title: A seroepidemiologic study of Reston ebolavirus in swine in the Philippines date: 2012-06-18 words: 4393.0 sentences: 222.0 pages: flesch: 53.0 cache: ./cache/cord-326770-yoefyowv.txt txt: ./txt/cord-326770-yoefyowv.txt summary: METHODS: A total of 215 swine sera collected at two REBOV-affected farms in 2008, in Pangasinan and Bulacan, were tested for the presence of REBOV-specific antibodies using multiple serodiagnosis systems. In the IFA, none of the 49 swine sera collected in Japan showed a positive reaction (data not shown), and so they were considered to be REBOV-NP and -GP antibody negative. In the IFA specific to REBOV-NP, antibody positive swine sera showed characteristic granular staining patterns in the cytoplasm ( Figure 1A ), which were indistinguishable from those of REBOV-infected cynomolgus monkey sera [18] and REBOV-NP immunized rabbit sera (data not shown). In total, 158 (73.5%) and 169 (78.6%) of the 215 swine sera collected at the affected farms were REBOV-NP and -GP antibody positive in the IFA, respectively (Table 1) . In total, 177 (82.3%) and 165 (76.7%) of the 215 swine sera collected at the affected farms were REBOV-NP and -GP antibody positive in the IgG-ELISA, respectively (Table 1) . abstract: BACKGROUND: Ebola viruses cause viral hemorrhagic fever in humans and non-human primates and are endemic in Africa. Reston ebolavirus (REBOV) has caused several epizootics in cynomolgus monkeys (Macaca fascicularis) but is not associated with any human disease. In late 2008, REBOV infections were identified in swine for the first time in the Philippines. METHODS: A total of 215 swine sera collected at two REBOV-affected farms in 2008, in Pangasinan and Bulacan, were tested for the presence of REBOV-specific antibodies using multiple serodiagnosis systems. A total of 98 swine sera collected in a non-epizootic region, Tarlac, were also tested to clarify the prevalence of REBOV infection in the general swine population in the Philippines. RESULTS: Some 70 % of swine sera at the affected farms were positive for REBOV antibodies in the multiple serodiagnosis systems. On the other hand, none of the swine sera collected in Tarlac showed positive reactions in any of the diagnosis systems. CONCLUSIONS: The high prevalence of REBOV infection in swine in the affected farms in 2008 suggests that swine is susceptible for REBOV infection. The multiple serological assays used in the study are thought to be useful for future surveillance of REOBV infection in swine in the Philippines. url: https://doi.org/10.1186/1746-6148-8-82 doi: 10.1186/1746-6148-8-82 id: cord-002087-o8kffjw0 author: Shi, Xibao title: Nonstructural protein 11 (nsp11) of porcine reproductive and respiratory syndrome virus (PRRSV) promotes PRRSV infection in MARC-145 cells date: 2016-06-06 words: 2620.0 sentences: 181.0 pages: flesch: 59.0 cache: ./cache/cord-002087-o8kffjw0.txt txt: ./txt/cord-002087-o8kffjw0.txt summary: title: Nonstructural protein 11 (nsp11) of porcine reproductive and respiratory syndrome virus (PRRSV) promotes PRRSV infection in MARC-145 cells RESULTS: Here, we firstly explored the effect of over-expression of nsp11 on PRRSV infection and found that over-expression of nsp11 enhanced the PRRSV titers while the small interfering RNA (siRNAs) specifically targeting nsp11 could reduce the PRRSV titers in MARC-145 cells.

[18] we used Affymetrix wholegenome chicken microarrays to examine the tracheal gene expression profiles of a line of birds known to be susceptible to IBV infection (line 15I) and a line known to show resistance (line N). Gene expression differences found in the susceptible 15I line between infected and control birds over days 2, 3 and 4 post infection were analysed, with a view to examining the innate host response to infection by IBV. Gene expression seen during the host response to IBV infection in the trachea of susceptible birds. Genes found to be differentially expressed between susceptible and resistant lines in response to IBV infection in the trachea. abstract: BACKGROUND: Infectious Bronchitis is a highly contagious respiratory disease which causes tracheal lesions and also affects the reproductive tract and is responsible for large economic losses to the poultry industry every year. This is due to both mortality (either directly provoked by IBV itself or due to subsequent bacterial infection) and lost egg production. The virus is difficult to control by vaccination, so new methods to curb the impact of the disease need to be sought. Here, we seek to identify genes conferring resistance to this coronavirus, which could help in selective breeding programs to rear chickens which do not succumb to the effects of this disease. METHODS: Whole genome gene expression microarrays were used to analyse the gene expression differences, which occur upon infection of birds with Infectious Bronchitis Virus (IBV). Tracheal tissue was examined from control and infected birds at 2, 3 and 4 days post-infection in birds known to be either susceptible or resistant to the virus. The host innate immune response was evaluated over these 3 days and differences between the susceptible and resistant lines examined. RESULTS: Genes and biological pathways involved in the early host response to IBV infection were determined andgene expression differences between susceptible and resistant birds were identified. Potential candidate genes for resistance to IBV are highlighted. CONCLUSIONS: The early host response to IBV is analysed and potential candidate genes for disease resistance are identified. These putative resistance genes can be used as targets for future genetic and functional studies to prove a causative link with resistance to IBV.

The network is very fragmented with 30 components, but there is a highly connected core of communes, consisting of a giant weak component and a sparse periphery (containing numerous Table 1 Attributes of "sell only" and "buy and sell" live poultry traders operating in all (total of 12) authorised live bird markets serving the Northern provinces of Vietnam. In particular, our analyses indicate that new LPT''s (i.e. those trading for less than a year) and those operating in authorised retail LBM''s have increased odds of sourcing poultry from flocks located in communes with past history of H5N1 outbreaks during 2003 to 2006, when compared to older LPT''s (i.e. those trading for more than a year) and to those operating in wholesale markets. abstract: BACKGROUND: The structure of contact between individuals plays an important role in the incursion and spread of contagious diseases in both human and animal populations. In the case of avian influenza, the movement of live birds is a well known risk factor for the geographic dissemination of the virus among poultry flocks. Live bird markets (LBM's) contribute to the epidemiology of avian influenza due to their demographic characteristics and the presence of HPAI H5N1 virus lineages. The relationship between poultry producers and live poultry traders (LPT's) that operate in LBM's has not been adequately documented in HPAI H5N1-affected SE Asian countries. The aims of this study were to document and study the flow of live poultry in a poultry trade network in northern Vietnam, and explore its potential role in the risk for HPAI H5N1 during 2003 to 2006. RESULTS: Our results indicate that LPT's trading for less than a year and operating at retail markets are more likely to source poultry from flocks located in communes with a past history of HPAI H5N1 outbreaks during 2003 to 2006 than LPT's trading longer than a year and operating at wholesale markets. The results of the network analysis indicate that LPT's tend to link communes of similar infection status. CONCLUSIONS: Our study provides evidence which can be used for informing policies aimed at encouraging more biosecure practices of LPT's operating at authorised LBM's. The results suggest that LPT's play a role in HPAI H5N1 transmission and may contribute to perpetuating HPAI H5N1 virus circulation amongst certain groups of communes. The impact of current disease prevention and control interventions could be enhanced by disseminating information about outbreak risk and the implementation of a formal data recording scheme at LBM's for all incoming and outgoing LPT's. url: https://doi.org/10.1186/1746-6148-6-10 doi: 10.1186/1746-6148-6-10 id: cord-333477-slcvbzt9 author: Sugita, Koji title: Oral faecal microbiota transplantation for the treatment of Clostridium difficile-associated diarrhoea in a dog: a case report date: 2019-01-07 words: 2510.0 sentences: 138.0 pages: flesch: 46.0 cache: ./cache/cord-333477-slcvbzt9.txt txt: ./txt/cord-333477-slcvbzt9.txt summary: title: Oral faecal microbiota transplantation for the treatment of Clostridium difficile-associated diarrhoea in a dog: a case report BACKGROUND: Successful clinical outcomes of faecal microbiota transplantation (FMT) for recurrent Clostridium difficile infection have been reported in humans and a marmoset. Four months prior to the current presentation, a faecal sample of the dog was subjected to real-time PCR analysis (IDEXX Laboratories, Inc., Tokyo, Japan) for Cryptosporidium spp., Giardia spp., Clostridium perfringens α toxin, Clostridium difficile toxin A&B, Campylobacter jejuni, Campylobacter coli, Salmonella spp., Canine parvovirus type 2, canine distemper virus and canine enteric coronavirus genes by a veterinary practitioner; a positive reaction for Campylobacter jejuni was detected in the analysis. difficile antigen and toxin A&B genes and proteins turned into negative, and stool consistency and frequency and faecal blood and mucus became normal after oral FMT in a dog with large bowel diarrhoea. abstract: BACKGROUND: Successful clinical outcomes of faecal microbiota transplantation (FMT) for recurrent Clostridium difficile infection have been reported in humans and a marmoset. However, it has been unclear whether oral FMT was effective for the treatment of C. difficile-associated diarrhoea in dogs. CASE PRESENTATION: An 8-month-old, intact male French bulldog was presented with a 4-month history of intermittent large bowel diarrhoea. Physical and clinical examinations did not identify any specific causes for diarrhoea. Real-time PCR analysis and immunochromatography detected C. difficile antigen and toxin A&B genes and proteins in a faecal sample. Based on these findings, diarrhoea in the dog was considered to be induced by C. difficile-associated colitis. The dog was treated with oral FMT, in which a faecal solution obtained from a healthy beagle was orally administered to the subject. Stool consistency and frequency and faecal blood and mucus became normal 2–3 days after oral FMT, and real-time PCR analysis and immunochromatography was negative for C. difficile antigen and toxin A&B genes and proteins. No adverse events were observed. CONCLUSION: The present case report demonstrated that oral FMT was an effective treatment for C. difficile-associated diarrhoea in a dog. The findings in this report provide a rationale to evaluate clinical efficacy of oral FMT for other gastrointestinal diseases in dogs. url: https://doi.org/10.1186/s12917-018-1754-z doi: 10.1186/s12917-018-1754-z id: cord-355465-qjtifwhd author: Van Diep, Nguyen title: Molecular characterization of US-like and Asian non-S INDEL strains of porcine epidemic diarrhea virus (PEDV) that circulated in Japan during 2013–2016 and PEDVs collected from recurrent outbreaks date: 2018-03-14 words: 6006.0 sentences: 267.0 pages: flesch: 54.0 cache: ./cache/cord-355465-qjtifwhd.txt txt: ./txt/cord-355465-qjtifwhd.txt summary: title: Molecular characterization of US-like and Asian non-S INDEL strains of porcine epidemic diarrhea virus (PEDV) that circulated in Japan during 2013–2016 and PEDVs collected from recurrent outbreaks RESULTS: Phylogenetic analysis based on S gene sequences revealed that all the recent field PEDVs were genetically distinct from the classical Japanese strains, and were classified into three genotypes: North American (NA), S INDEL, and Asian non-S INDEL. Another subclade, designated as PED-J2, including 14 Japanese strains collected in Miyazaki were also clustered into a segregated branch as shown in Fig. 1 The sequence data revealed that S genes from the Japanese field PEDVs are of 4152-4161 nt long, and encode proteins with 1381-1386 aa residues. Cell culture isolation and sequence analysis of genetically diverse US porcine epidemic diarrhea virus strains including a novel strain with a large deletion in the spike gene abstract: BACKGROUND: Since late 2013, porcine epidemic diarrhea virus (PEDV) has reemerged in Japan and caused severe economic losses to the swine industry. Although PEDV vaccines have been used widely, the disease has swept rapidly across the county, and is commonly observed in PED-vaccinated farms, and has recurred in domestic herds. To better understand PEDVs responsible for the reemerging outbreaks in Japan, full-length spike (S), membrane (M), and nucleocapsid (N) genes of 45 PEDVs collected in Japan during 2013–2016, were sequenced and analyzed. RESULTS: Phylogenetic analysis based on S gene sequences revealed that all the recent field PEDVs were genetically distinct from the classical Japanese strains, and were classified into three genotypes: North American (NA), S INDEL, and Asian non-S INDEL. Our data suggested a possibility that multiple parental PEDV strains were introduced into Japan from abroad at the same time or similar times. The newly identified Japanese strains showed the closest relationship to the US strains. Two sublineages of Japanese strains circulating in Japan were similar to two sublineages identified in the US, suggesting common ancestors for these strains. In comparison with two vaccine strains used in Japan, the field strains had various changes in epitope regions, glycosylation sites, and phosphorylation sites. These substitutions, particularly observed in epitope regions of the S (521, 553, 568, and 570), M (5), and N (123, 252, and 255) proteins, may have affected antigenicity and vaccine efficacy, resulting in an unsuccessful PEDV control. Sequence comparisons between PEDVs collected from primary and secondary outbreaks in three herds revealed that the disease has developed to an endemic stage in which PEDV could persist for nearly two years in the herds or local regions, causing subsequent epidemics. CONCLUSIONS: These results elucidate the genetic characteristics, origin, and molecular epidemiology of PEDVs circulating in Japan, as well as the PEDV strains causing recurrent outbreaks. This study provides a better insight into the PEDVs responsible for recent outbreaks in Japan, and could potentially help to develop measures for controlling and preventing the disease.

CONCLUSIONS: These results indicated that the dietary addition of SRB in milk did not have an effect in health, immunity or performance of pre-weaned dairy calves. We hypothesized that the addition of SRB in milk of pre-weaned calves would reduce the presentation and severity of neonatal diarrhea, improving the immune response and consequently the overall calf performance. The addition of prebiotics via SRB into milk starting at 6-7 days of age was assessed for effects on health and performance of pre-weaned organic dairy calves over a 28 days period. The major finding from this study was that the addition of SRB in the milk of newborn calves for 28 days did not enhance performance, health, or immunity during the first month of life, a period characterized for the presentation of digestive diseases. abstract: BACKGROUND: The first month of life possess significant challenges for dairy calves due to high susceptibility to digestive diseases. The objective of this study was to evaluate the effect of prebiotic supplementation with stabilized rice bran (SRB) in milk on health, immunity, and performance of pre-weaned organic dairy calves. Holstein heifer calves (n = 90) were enrolled at 6 ± 1 days old and monitored for 28 days, from July to August 2017. Calves were randomly assigned to a control (CTR; n = 45) or a treatment group (SRB; n = 45). The CTR group received milk alone and the SRB group received 120 g of SRB per day in milk to achieve a 10% w/w dose of the total calories. Daily health evaluations were conducted to score health status and disease severity (healthy, slightly affected, moderately or severely sick) of calves, through integrated assessment of diarrhea, dehydration, attitude, and milk intake. Body weights and fecal IgA quantification were completed on the first and last day of the study. RESULTS: Overall, weight gain and fecal IgA concentrations were not affected by the dietary addition of SRB. The total number of calf-days classified as healthy or sick were not different between treatment groups. Similarly, the number of calf-days categorized as slightly affected, moderately sick, or severely sick did not differ between treatment groups. Time to event analyses indicated a tendency for a treatment effect in the time to the first moderate case of diarrhea (P = 0.08), as well as in the time to recovery from diarrhea (P = 0.052), favoring control calves. CONCLUSIONS: These results indicated that the dietary addition of SRB in milk did not have an effect in health, immunity or performance of pre-weaned dairy calves. url: https://doi.org/10.1186/s12917-019-1802-3 doi: 10.1186/s12917-019-1802-3 id: cord-332572-9h26mj7w author: Wang, Jinfeng title: Development and validation of the isothermal recombinase polymerase amplification assays for rapid detection of Mycoplasma ovipneumoniae in sheep date: 2020-06-01 words: 2909.0 sentences: 144.0 pages: flesch: 47.0 cache: ./cache/cord-332572-9h26mj7w.txt txt: ./txt/cord-332572-9h26mj7w.txt summary: title: Development and validation of the isothermal recombinase polymerase amplification assays for rapid detection of Mycoplasma ovipneumoniae in sheep ovipneumoniae DNA was detected in 29 samples in the real-time RPA, 31 samples in the LFS RPA and 32 samples in the real-time PCR assay. In this study, a real-time RPA assay using the exo probe and a LFS RPA assay using the nfo probe combined with lateral flow strip were developed for rapid, specific and sensitive detection of M. ovipneumoniae DNA was detected in 29 (26.12%), 31 (27.93%) and 32 (28.83%) samples by the real-time RPA, LFS RPA and real-time PCR, respectively (Table 1 ).

Recombinase polymerase amplification (RPA) is an isothermal nucleic acid amplification technique, and RPA-based diagnostic assays have been described for the detection of different types of pathogens. RESULTS: The RPA assays using real-time fluorescence detection (real-time RPA) and lateral flow strip detection (LFS RPA) were developed to detect M. ovipneumoniae targeting a conserved region of the 16S rRNA gene. Real-time RPA was performed in a portable florescence scanner at 39 °C for 20 min. LFS RPA was performed in a portable metal bath incubator at 39 °C for 15 min, and the amplicons were visualized with the naked eyes within 5 min on the lateral flow strip. Both assays were highly specific for M. ovipneumoniae, as there were no cross-reactions with other microorganisms tested, especially the pathogens involved in respiratory complex and other mycoplasmas frequently identified in ruminants. The limit of detection of LFS RPA assay was 1.0 × 10(1) copies per reaction using a recombinant plasmid containing target gene as template, which is 10 times lower than the limit of detection of the real-time RPA and real-time PCR assays. The RPA assays were further validated on 111 clinical sheep nasal swab and fresh lung samples, and M. ovipneumoniae DNA was detected in 29 samples in the real-time RPA, 31 samples in the LFS RPA and 32 samples in the real-time PCR assay. Compared to real-time PCR, the real-time RPA and LFS RPA showed diagnostic specificity of 100 and 98.73%, diagnostic sensitivity of 90.63 and 93.75%, and a kappa coefficient of 0.932 and 0.934, respectively. CONCLUSIONS: The developed real-time RPA and LFS RPA assays provide the attractive and promising tools for rapid, convenient and reliable detection of M. ovipneumoniae in sheep, especially in resource-limited settings. However, the effectiveness of the developed RPA assays in the detection of M. ovipneumoniae in goats needs to be further validated. url: https://doi.org/10.1186/s12917-020-02387-3 doi: 10.1186/s12917-020-02387-3 id: cord-003587-zminzrov author: Wang, Xueyu title: Visual detection of porcine epidemic diarrhea virus using a novel reverse transcription polymerase spiral reaction method date: 2019-04-15 words: 3633.0 sentences: 173.0 pages: flesch: 48.0 cache: ./cache/cord-003587-zminzrov.txt txt: ./txt/cord-003587-zminzrov.txt summary: title: Visual detection of porcine epidemic diarrhea virus using a novel reverse transcription polymerase spiral reaction method The aim of this study was to establish a novel reverse transcription polymerase spiral reaction (RT-PSR) assay for the rapid detection of porcine epidemic diarrhea virus (PEDV). This new method for PEDV detection was 10 times more sensitive than the conventional reverse transcription-polymerase chain reaction (RT-PCR) assay. To decrease the time required for PEDV detection, PCR-related methods focused on the amplification of viral nucleic acids have been developed, which have been shown to be more efficient, highly sensitive and specific, even at different stages of the disease, when compared to immunological diagnostic methods. The polymerase spiral reaction (PSR) [14] is a novel nucleic acid isothermal amplification method that has the advantages of simplicity, rapidity, accuracy, and low cost when compared to conventional PCR. abstract: BACKGROUND: Porcine epidemic diarrhea virus (PEDV) is a major etiological agent of porcine epidemic diarrhea around the world. Point-of-care testing in the field is lacking owing to the requirement for a simple, robust field applicable test that does not require professional laboratory equipment. The aim of this study was to establish a novel reverse transcription polymerase spiral reaction (RT-PSR) assay for the rapid detection of porcine epidemic diarrhea virus (PEDV). For the assay, a specific RT-PSR primer pair was designed against a conserved region in PEDV ORF3. RESULTS: The RT-PSR was optimized, and PEDV could be detected after a 50 min incubation at 62 °C, in addition to the 15 min required for reverse transcription. No cross-reaction with other porcine infectious viruses was observed. This new method for PEDV detection was 10 times more sensitive than the conventional reverse transcription-polymerase chain reaction (RT-PCR) assay. The positive rates for 65 clinical samples using the new RT-PSR assay and the conventional RT-PCR assay were 58.46% (38/65) and 53.84% (35/65), respectively. In the RT-PSR assay, the addition of a mixture of dyes allowed a positive reaction to be directly observed by the naked eye. CONCLUSIONS: These results indicate that this RT-PSR assay is capable of accurately detecting PEDV, and has the advantages of high specificity and sensitivity for the detection of PEDV. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6466714/ doi: 10.1186/s12917-019-1851-7 id: cord-346457-2mq2aije author: Wang, Zhilin title: Rapid differentiation of PEDV wild-type strains and classical attenuated vaccine strains by fluorescent probe-based reverse transcription recombinase polymerase amplification assay date: 2020-06-22 words: 4770.0 sentences: 227.0 pages: flesch: 53.0 cache: ./cache/cord-346457-2mq2aije.txt txt: ./txt/cord-346457-2mq2aije.txt summary: RESULTS: In the study, a differential one-step quantitative real-time fluorescent reverse transcription recombinase polymerase amplification (real-time RT-RPA) method based on the PEDV universal real-time RT-RPA assay was established according to the ORF1 deletion sequences of three classical attenuated vaccine strains (PEDV attenuated vaccine KC189944, attenuated CV777 and DR13) and five Vero cell-adapted isolates (JS2008, SDM, SQ2014, SC1402, HLJBY), which could effectively differentiate PEDV classical attenuated vaccine strains from wild-type strains (PEDV classical wild strains and variant strains). The detection limits of PEDV RNA in the both PEDV real-time RT-RPA assays were 300 copies within 20 min at 39 °C, and the detection limits of classical attenuated vaccine strain CV777, Vero-cell-adapted isolate JS2008, and PEDV wild-type strain DX were 10(0.5) TCID(50)/100 μL, 10(1.1) TCID(50)/100 μL, and 10(1.2) TCID(50)/100 μL, respectively.

In recent years, despite the use of China’s current vaccine immunization strategy, multiple types of PEDV strains were still found in immunized swine herds. Our research aims to explore a new rapid differentiation method to distinguish the different types of PEDV strains and assess the safety evaluation of classical attenuated vaccine strains in swine herds. RESULTS: In the study, a differential one-step quantitative real-time fluorescent reverse transcription recombinase polymerase amplification (real-time RT-RPA) method based on the PEDV universal real-time RT-RPA assay was established according to the ORF1 deletion sequences of three classical attenuated vaccine strains (PEDV attenuated vaccine KC189944, attenuated CV777 and DR13) and five Vero cell-adapted isolates (JS2008, SDM, SQ2014, SC1402, HLJBY), which could effectively differentiate PEDV classical attenuated vaccine strains from wild-type strains (PEDV classical wild strains and variant strains).

Both assays were highly specific for PEDV, showing no cross-reactivity with other enteral viruses. CONCLUSION: This RPA method we developed is simple, time-effective, and safe and provides a reliable technical tool for the differential diagnosis and clinical epidemic surveillance of PEDV classical attenuated vaccine strains and wild-type strains. url: https://doi.org/10.1186/s12917-020-02424-1 doi: 10.1186/s12917-020-02424-1 id: cord-279551-py2awuav author: Willi, Barbara title: Clinical and molecular investigation of a canine distemper outbreak and vector-borne infections in a group of rescue dogs imported from Hungary to Switzerland date: 2015-07-16 words: 6264.0 sentences: 315.0 pages: flesch: 53.0 cache: ./cache/cord-279551-py2awuav.txt txt: ./txt/cord-279551-py2awuav.txt summary: title: Clinical and molecular investigation of a canine distemper outbreak and vector-borne infections in a group of rescue dogs imported from Hungary to Switzerland In the present study, we describe a distemper outbreak in 15 rescue dogs that were imported from Hungary to Switzerland by an animal welfare organisation. Canine distemper virus (CDV) is one of the most important viral pathogens in domestic dogs and causes high morbidity and mortality worldwide, particularly in unvaccinated dogs or dogs with incomplete vaccination [1] . The study provides data on vaccination, medical history, clinical examinations and diagnostic imaging of the dogs and CDV testing, testing for canine parvovirus (CPV) and vector-borne infections. The vaccine-specific real-time reverse transcription (RT)quantitative (q)PCR was negative for all ten dogs that were tested, which supports the finding of infection with a wild-type CDV strain. abstract: BACKGROUND: Canine distemper virus (CDV) is a major pathogen of dogs and wild carnivores worldwide. In Switzerland, distemper in domestic dogs is rarely reported. In recent years, the import of dogs from Eastern Europe to Switzerland has steadily increased. In the present study, we describe a distemper outbreak in 15 rescue dogs that were imported from Hungary to Switzerland by an animal welfare organisation. The data on vaccination and medical history were recorded (14 dogs), and the samples were collected to investigate CDV and vector-borne infections (13 dogs) and canine parvovirus infection (12 dogs). The dogs were monitored for six months. RESULTS: One dog was euthanised directly after import. Thirteen dogs showed clinical signs after arrival, i.e., diarrhoea (57 %), coughing (43 %) and nasal and/or ocular discharge (21 %); radiographic findings that were compatible with bronchopneumonia were present in four dogs. CDV infection was diagnosed in 11 dogs (85 %); 10 dogs (91 %) tested PCR-positive in conjunctival swabs. Vector-borne infections (Babesia spp., Leishmania infantum, Dirofilaria immitis) were found in 4 dogs (31 %). Three dogs were hospitalized, and six dogs received ambulatory therapy for up to two months until recovery. None of the dogs developed neurological disease. CDV shedding was detected for a period of up to four months. Because dogs were put under strict quarantine until CDV shedding ceased, CDV did not spread to any other dogs. The CDV isolates showed 99 % sequence identity in the HA gene among each other and belonged to the Arctic-like lineage of CDV. CONCLUSIONS: The present study highlights the imminent risks of spreading contagious viral and vector-borne infections through the non-selective import of sick dogs and dogs with incomplete vaccination from Eastern Europe. CDV shedding was detected for several months after the cessation of clinical signs, which emphasised the roles of asymptomatic carriers in CDV epidemiology. A long-term follow-up using sensitive PCR and strict quarantine measures is of upmost importance in preventing the spread of infection. Dog owners and animal welfare organisations should be educated regarding the importance of complete vaccinations and the impact of dog imports on the spread of viral and vector-borne pathogens. url: https://www.ncbi.nlm.nih.gov/pubmed/26179635/ doi: 10.1186/s12917-015-0471-0 id: cord-260348-83ftjqev author: Xu, Yinlan title: Cepharanthine and Curcumin inhibited mitochondrial apoptosis induced by PCV2 date: 2020-09-18 words: 3752.0 sentences: 220.0 pages: flesch: 48.0 cache: ./cache/cord-260348-83ftjqev.txt txt: ./txt/cord-260348-83ftjqev.txt summary: The results of qPCR and Western blot showed that, compared with the PCV2 infected group, the expression of Cap in Paeonol (0.4 mg/mL and 0.2 mg/mL), Cepharanthine (0.003 mg/mL, 0.0015 mg/mL and 0.00075 mg/mL) and Curcumin (0.02 mg/mL, 0.001 mg/mL and 0.005 mg/mL) treated groups were significantly lowered in a dose-dependent manner. The results of Annexin V-FITC/PI, JC-1, Western blot and ROS analysis showed that the expression of cleaved caspase-3 and Bax were up-regulated Bcl-2 was down-regulated in Cepharanthine or Curcumin treated groups, while ROS and MMP value were decreased at different degrees and the apoptosis rate was reduced. The results showed that Compared to the PCV2-infected group, the cell apoptosis rates were significantly decreased in the group treated with Cepharanthine, Curcumin or Ribavirin, demonstrating a dose-dependent response except the group of 0.005 mg/mL Paeonol (P < 0.05) ( Fig. 3a and b). abstract: BACKGROUND: Porcine circovirus type 2 (PCV2) is an immunosuppressive pathogen with high prevalence rate in pig farms. It has caused serious economic losses to the global pig industry. Due to the rapid mutation of PCV2 strain and co-infection of different genotypes, vaccination could not eradicate the infection of PCV2. It is necessary to screen and develop effective new compounds and explore their anti-apoptotic mechanism. The 13 natural compounds were purchased, with a clear plant origin, chemical structure and content and specific biological activities. RESULTS: The maximum no-cytotoxic concentration (MNTC) and 50% cytotoxic concentration (CC(50)) of 13 tested compounds were obtained by the cytopathologic effect (CPE) assay and (3-(4,5-dimethyithiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method in PK-15 cells. The results of qPCR and Western blot showed that, compared with the PCV2 infected group, the expression of Cap in Paeonol (0.4 mg/mL and 0.2 mg/mL), Cepharanthine (0.003 mg/mL, 0.0015 mg/mL and 0.00075 mg/mL) and Curcumin (0.02 mg/mL, 0.001 mg/mL and 0.005 mg/mL) treated groups were significantly lowered in a dose-dependent manner.

In this study, Ribavirin was used as a positive control. CONCLUSIONS: Paeonol, Cepharanthine and Curcumin have significant antiviral effect. And the PCV2-induced Mitochondrial apoptosis was mainly remitted by Cepharanthine and Curcumin. url: https://www.ncbi.nlm.nih.gov/pubmed/32948186/ doi: 10.1186/s12917-020-02568-0 id: cord-003208-lwirkob3 author: Yan, Liping title: Novel protein chip for the detection of antibodies against infectious bronchitis virus date: 2018-09-17 words: 3973.0 sentences: 220.0 pages: flesch: 52.0 cache: ./cache/cord-003208-lwirkob3.txt txt: ./txt/cord-003208-lwirkob3.txt summary: RESULTS: We have developed two indirect microarray methods to detect antibodies against IBV: a chemiluminescent immunoassay test (CIT) and a rapid diagnostic test (RDT). Compared with these methods, enzyme-linked immunosorbent assay (ELISA) has been widely used for testing IBV early infection and continuous infection, and this technique can be used for both antigenic and antibody detection. The data showed that 130 serum samples were positive for antibodies against IBV, and 14 samples were negative, similar to the results of the IDEXX IBV Ab Test kit with the nsp5 concentration of 0.2 mg/mL (Table 4 ). The specific experiments of the RDT showed that no cross-reaction Fig. 4 a Distribution of the SNRs of the IDEXX-positive (n = 142) and IDEXX-negative (n = 42) serum samples of the clinical sera obtained from the IBV protein microarray. abstract: BACKGROUND: Infectious bronchitis (IB) caused by the IB virus (IBV) can cause acute damage to chickens around the world. Therefore, rapid diagnosis and immune status determination are critical for controlling IBV outbreaks. Enzyme-linked immunosorbent assays (ELISAs) have been widely used in the detection of IBV antibodies in the early infection and continuous infection of IB because they are more sensitive and quicker than other diagnostic methods. RESULTS: We have developed two indirect microarray methods to detect antibodies against IBV: a chemiluminescent immunoassay test (CIT) and a rapid diagnostic test (RDT). IBV nonstructural protein 5 (nsp5) was expressed, purified from Escherichia coli, and used to spot the initiator integrated poly(dimethylsiloxane), which can provide a near “zero” background for serological assays. Compared with the IDEXX IBV Ab Test kit, CIT and RDT have a sensitivity and specificity of at least 98.88% and 91.67%, respectively. No cross-reaction was detected with antibodies against avian influenza virus subtypes (H5, H7, and H9), Newcastle disease virus, Marek’s disease virus, infectious bursal disease virus, and chicken anemia virus. The coefficients of variation of the reproducibility of the intra- and inter-assays for CIT ranged from 0.8 to 18.63%. The reproducibility of RDT was consistent with the original results. The application of the IBV nsp5 protein microarray showed that the positive rate of the CIT was 96.77%, that of the nsp5 ELISA was 91.40%, and that of the RDT was 90.32%. Furthermore, the RDT, which was visible to the naked eye, could be completed within 15 min. Our results indicated that compared with nsp5 ELISA, the CIT was more sensitive, and the RDT had similar positive rates but was faster. Furthermore, the two proposed methods were specific and stable. CONCLUSIONS: Two microarray assays, which were rapid, specific, sensitive, and relatively simple, were developed for the detection of an antibody against IBV. These methods can be of great value for the surveillance of pathogens and monitoring the efficiency of vaccination. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6142349/ doi: 10.1186/s12917-018-1586-x id: cord-261446-ro1wm0kf author: Yang, Yifei title: Fatal disease associated with Swine Hepatitis E virus and Porcine circovirus 2 co-infection in four weaned pigs in China date: 2015-03-26 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: In recent decades, Porcine circovirus 2 (PCV2) infection has been recognized as the causative agent of postweaning multisystemic wasting syndrome, and has become a threat to the swine industry. Hepatitis E virus (HEV) is another high prevalent pathogen in swine in many regions of the world. PCV2 and HEV are both highly prevalent in pig farms in China. CASE PRESENTATION: In this study, we characterized the HEV and PCV2 co-infection in 2–3 month-old piglets, based on pathogen identification and the pathological changes observed, in Hebei Province, China. The pathological changes were severe, and general hyperemia, hemorrhage, inflammatory cell infiltration, and necrosis were evident in the tissues of dead swine. PCR was used to identify the pathogen and we tested for eight viruses (HEV, Porcine reproductive and respiratory syndrome virus, PCV2, Classical swine fever virus, Porcine epidemic diarrhea virus, Transmissible gastroenteritis coronavirus, Porcine parvovirus and Pseudorabies virus) that are prevalent in Chinese pig farms. The livers, kidneys, spleens, and other organs of the necropsied swine were positive for HEV and/or PCV2. Immunohistochemical staining showed HEV- and PCV2-antigen-positive signals in the livers, kidneys, lungs, lymph nodes, and intestine. CONCLUSION: HEV and PCV2 co-infection in piglets was detected in four out of seven dead pigs from two pig farms in Hebei, China, producing severe pathological changes. The natural co-infection of HEV and PCV2 in pigs in China has rarely been reported. We speculate that co-infection with PCV2 and HEV may bring some negative effect on pig production and recommend that more attention should be paid to this phenomenon. url: https://www.ncbi.nlm.nih.gov/pubmed/25889526/ doi: 10.1186/s12917-015-0375-z id: cord-313445-4v7pjqt2 author: Zhao, Jun title: Porcine interferon lambda 3 (IFN-λ3) shows potent anti-PRRSV activity in primary porcine alveolar macrophages (PAMs) date: 2020-10-28 words: 3385.0 sentences: 235.0 pages: flesch: 60.0 cache: ./cache/cord-313445-4v7pjqt2.txt txt: ./txt/cord-313445-4v7pjqt2.txt summary: title: Porcine interferon lambda 3 (IFN-λ3) shows potent anti-PRRSV activity in primary porcine alveolar macrophages (PAMs) In addition, IFN-λ3 in our study was able to induce the expression of interferon-stimulated genes 15 (ISG15), 2′-5′-oligoadenylate synthase 1 (OAS1), IFN-inducible transmembrane 3 (IFITM3), and myxoma resistance protein 1(Mx1) in primary PAMs. CONCLUSIONS: IFN-λ3 had antiviral activity against PRRSV and can stimulate the expression of pivotal interferon-stimulated genes (ISGs), i.e., ISG15, Mx1, OAS1, and IFITM3. The virus titre was significantly reduced with the increase of IFN-λ3 treatment dose (10, Fig. 1 The CPE of primary PAMs treated with Porcine IFN-λ3 and infected with PRRSV. The expression of mRNA for ISG15, Mx1, OAS1, and IFIT M3 was up-regulated by 70, 70, 160, and 15 times respectively at the concentration of 1000 ng/ml in primary PAMs. As shown in Fig. 3e and f (The full-length blots are presented in Supplementary file 2), a dosedependent induction of the antiviral proteins ISG15, Mx1 and OAS1 has been observed in primary PAMs treated with IFN-λ3. abstract: BACKGROUND: Porcine reproductive and respiratory syndrome virus (PRRSV) is a serious viral disease of swine. At present, there are vaccines for the control of PRRSV infection, but the effect is not satisfactory. The recombination of attenuated vaccines causes significant difficulties with the prevention and control of PRRSV. Type III interferons (IFNs), also called IFN-λs, were newly identified and showed potent antiviral activity within the mucosal surface and immune organs. RESULTS: Therefore, primary porcine alveolar macrophages (PAMs) were used for this investigation. To this end, we found that the replication of PRRSV in PAMs was significantly reduced after pre-treatment with IFN-λ3, and such inhibition was dose- and time-dependent. The plaque formation of PRRSV abrogated entirely, and virus yields were reduced by four orders of magnitude when the primary PAMs were treated with IFN-λ3 at 1000 ng/ml. In addition, IFN-λ3 in our study was able to induce the expression of interferon-stimulated genes 15 (ISG15), 2′-5′-oligoadenylate synthase 1 (OAS1), IFN-inducible transmembrane 3 (IFITM3), and myxoma resistance protein 1(Mx1) in primary PAMs. CONCLUSIONS: IFN-λ3 had antiviral activity against PRRSV and can stimulate the expression of pivotal interferon-stimulated genes (ISGs), i.e., ISG15, Mx1, OAS1, and IFITM3. So, IFN-λ3 may serve as a useful antiviral agent.
