Summary of your 'study carrel' ============================== This is a summary of your Distant Reader 'study carrel'. The Distant Reader harvested & cached your content into a collection/corpus. It then applied sets of natural language processing and text mining against the collection. The results of this process was reduced to a database file -- a 'study carrel'. The study carrel can then be queried, thus bringing light specific characteristics for your collection. These characteristics can help you summarize the collection as well as enumerate things you might want to investigate more closely. This report is a terse narrative report, and when processing is complete you will be linked to a more complete narrative report.

pig; virus summary = SUMMARY: Forty‐eight pigs were inoculated by different routes with the VW 572 isolate of the hemagglutinating encephalomyelitis (vomiting and wasting disease) virus. The present studies were primarily designed to determine whether a virus isolate, obtained from pigs with the vomiting and wasting syndrome only, could produce clinical signs after inoculation by different routes. When sick, pigs were killed at time intervals varying from one to five days after the appearance of clinical signs and different tissues were collected for virus isolation. From the pigs killed at different time intervals after inoculation, the following tissues were collected for virus isolation : nasal mucosa, tonsils, lungs (apical and cardiac lobes), pyloric region of the stomach, pons and medulla combined, cerebrum, cerebellum and blood clot. Forty-eight pigs were inoculated by different routes with the VW 572 isolate of the hemagglutinating encephalomyelitis (vomiting and wasting disease) virus. doi = 10.1111/j.1439-0450.1978.tb00754.x id = cord-003447-kbpvt5on author = Atherstone, C. title = Analysis of pig trading networks and practices in Uganda date = 2018-08-02 keywords = Uganda; Wambizzi; pig; trader summary = This study interviewed pig traders operating at Uganda''s only registered pork abattoir to describe their characteristics, business practices, biosecurity practices, and pig health management and reporting practices. Given pig traders'' important role in supplying pork for a rapidly expanding consumer base and linking farmers with consistent markets, a better understanding of their practices and motivations around purchasing, transportation, and pig health management is needed. Therefore, the objectives of this study were to (1) describe pig trader characteristics, trading practices, biosecurity practices, pig health management, and reporting practices and (2) map source locations of pigs purchased to supply pork through the major abattoir in Uganda. Furthermore, we observed trader brands on pigs at slaughter (e.g., number or letter carved on the animal at the time of purchase) and asked participants who had completed the interview if they could identify the trader who supplied the pig. doi = 10.1007/s11250-018-1668-6 id = cord-013174-whg64w0w author = Bhatta, Tarka Raj title = Infection Dynamics of Swine Influenza Virus in a Danish Pig Herd Reveals Recurrent Infections with Different Variants of the H1N2 Swine Influenza A Virus Subtype date = 2020-09-10 keywords = IAV; pig; week summary = In addition, next generation sequencing (NGS) was used to identify and characterize the complete genome of swIAV circulating in the herd, and to examine the antigenic variability in the antigenic sites of the virus hemagglutinin (HA) and neuraminidase (NA) proteins. In pigs, circulation of IAV, so-called swine influenza A virus (swIAV), is currently mainly limited to three different subtypes including H1N1, H1N2 and H3N2 [5] [6] [7] . In the phylogenetic analysis, the HA sequences of pig ID 250, obtained at weeks 4 and 8 were located in the same cluster and were~0.5% (9/1701) divergent at the nucleotide level and < 1% (5/566) divergent at the amino acid level.

Although guinea pigs are sensitive and susceptible to the development of lesions from a wide range of viruses, bacteria, protozoa, and parasites, only a small number of organisms cause natural infection and only a portion of that group cause clinical disease. The efficacy of canine, porcine, human, and autogenous Bordetella vaccines and bacterins has been evaluated by several individuals; reports suggest that these vaccines do not completely protect guinea pigs from infection, but a decrease in the incidence and severity of clinical disease has been noted in experimentally challenged animals (Matherne et al., 1987; Stephenson et al., 1989) . doi = 10.1016/b978-0-12-380920-9.00023-7 id = cord-285585-tigj7fhc author = Cleveland, Christopher A. title = Survey for selected pathogens in wild pigs (Sus scrofa) from Guam, Marianna Islands, USA date = 2017-05-03 keywords = Guam; Leptospira; pig summary = Exposure to porcine parvovirus, transmissible gastroenteritis, and Leptospira interrogans has been documented in domestic swine but data from wild pigs are lacking. In contrast to the previous domestic swine survey, we found evidence of numerous pathogens in wild pigs including new reports of pseudorabies virus, PRRS virus, Brucella, and Leptospira in pigs on Guam. Recent reports of leptospirosis in residents and tourists is one concern and although rodents tend be considered the most common reservoir of Leptospira, there is evidence of Leptospira in domestic swine on Guam (Dugies et al., 2000) , and wild pigs in numerous countries have antibodies to leptospires (Jansen et al., 2007; Corn et al., 1986) . Samples collected from these animals were used to conduct a comprehensive surveillance project on pathogen exposure of wild pigs on Guam. No evidence of exposure to Trichinella spp., IAV, or coronaviruses associated with enteric and respiratory disease was found; one pig had antibodies to porcine epidemic diarrhea virus. doi = 10.1016/j.vetmic.2017.05.001 id = cord-351834-9pclxek0 author = Cohen, Liza Miriam title = A descriptive study of acute outbreaks of respiratory disease in Norwegian fattening pig herds date = 2020-06-24 keywords = herd; norwegian; outbreak; pig summary = title: A descriptive study of acute outbreaks of respiratory disease in Norwegian fattening pig herds The main objective of this study was to investigate acute outbreaks of respiratory disease in conventional Norwegian fattening pig herds. In seven herds with reported outbreaks of acute respiratory disease, data on clinical signs was recorded and samples for laboratory examination were collected. Actinobacillus pleuropneumoniae serovar 8 was isolated from lungs and/or pleura from all tested pigs (n = 28) in the outbreak herds, and from 2 out of 24 pigs (8%) in the non-outbreak herds, one pig with an acute and another pig with a chronic infection. The main objective of this study was to investigate clinical outbreaks of acute respiratory disease in Norwegian fattening pig herds, using a group of non-outbreak herds to compare diagnostic procedures. The inclusion criteria for outbreak herds were; three or more pigs displaying acute signs of respiratory disease including fever and coughing and/or dyspnea, and/ or otherwise reduced general condition e.g. lethargy or inappetence. doi = 10.1186/s13028-020-00529-z id = cord-308767-trwa5grl author = Costa Vallés, Cristina title = Transgenic Organs and Xenotransplants date = 2012-03-20 keywords = AHXR; DQG; WKH; pig summary = 13 Subsequent studies showed survival times of up to 11 days for kidneys of alpha1,3-GT knockout pigs transplanted in baboons, meaning that the organs of these transgenic pigs were also protected against HAR, 14 as occurred in animals transgenic for human complement regulatory proteins.

To prevent this, a broad screening program of the donor animals for putative zoonotic microorganisms, including bacteria, viruses, fungi and others, using sensitive and specific detection methods has to be performed. In the case of porcine endogenous retroviruses (PERVs) which are integrated in the genome of all pigs and which cannot be eliminated this way, selection of animals with low virus expression and generation of genetically modified pigs suppressing PERV expressions may be performed. At the moment hepatitis E virus (HEV), porcine cytomegalovirus (PCMV), porcine circoviruses (PCV), porcine lymphotropic herpes viruses (PLHV), and porcine endogenous retroviruses (PERVs) are thought to pose the main risk for reasons to be discussed below and therefore these microorganisms will be analysed in the next chapters in more details. doi = 10.1016/j.ijsu.2015.08.032 id = cord-266199-smlq11y9 author = Dhakal, Santosh title = Nanoparticle-based vaccine development and evaluation against viral infections in pigs date = 2019-11-06 keywords = PLGA; PRRSV; pig; porcine; vaccine; virus summary = The economic burden caused by virus infections such as Porcine Reproductive and Respiratory Syndrome Virus, Swine influenza virus, Porcine Epidemic Diarrhea Virus, Porcine Circovirus 2, Foot and Mouth Disease Virus and many others are associated with severe morbidity, mortality, loss of production, trade restrictions and investments in control and prevention practices. Likewise, DCs targeted chitosan NPs loading plasmid DNA encoding nucleocapsid protein of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) induced better nucleocapsid protein-specific mucosal IgA antibody response compared to soluble unentrapped antigens after nasal immunization in mice [57] . In this review, only studies conducted in pigs related to the development and evaluation of NPs-based vaccine candidates by using virus-like particles (VLPs), biodegradable polymers, polysaccharides and liposomes against porcine viral infections are included (Table 3) . Chitosan-based NPs are used in pigs to deliver adjuvants such as bee venom and plasmid encoding porcine IL-2 and IL-4/IL-6 genes, which improved induction of better virus-specific immune responses of respective vaccines against PRRSV and PCV2 [103, 104] . doi = 10.1186/s13567-019-0712-5 id = cord-273705-0oyzg5tq author = Duffy, Mark A title = Impact of dietary spray-dried bovine plasma addition on pigs infected with porcine epidemic diarrhea virus date = 2018-08-29 keywords = PEDV; SDP; pig summary = title: Impact of dietary spray-dried bovine plasma addition on pigs infected with porcine epidemic diarrhea virus Experimental data suggest that the addition of spray-dried plasma (SDP) to pig feed may enhance antibody responses against certain pathogens and negatively impact virus survival. The aim of this study was to determine the effect of bovine SDP (BovSDP) in the pig diet on acute porcine epidemic diarrhea virus (PEDV) infection. The results indicate that addition of BovSDP induced an earlier anti-PEDV antibody response in pigs experimentally infected with PEDV thereby reducing clinical disease and the amount and duration of viral shedding during acute PEDV infection. Starting with arrival in the research facility and for the duration of the study, all pigs were fed the same standard commercial corn-soybean meal-dried whey-based diet ( Table 2 ) except for the diet of the PEDV-BovSDP group, which was supplemented with 5% spray-dried commercial bovine plasma replacing soy protein concentrate on an equal total lysine basis ( Figure 1 ). doi = 10.1093/tas/txy088 id = cord-348522-r7ev9br6 author = Englund, Stina title = The occurrence of Chlamydia spp. in pigs with and without clinical disease date = 2012-01-26 keywords = Chlamydia; PCR; pig summary = doi = 10.1186/1746-6148-8-9 id = cord-277487-jgbjxgh1 author = Graham, Simon P. title = Evaluation of the immunogenicity of prime-boost vaccination with the replication-deficient viral vectored COVID-19 vaccine candidate ChAdOx1 nCoV-19 date = 2020-06-20 keywords = CoV-2; IFN; SARS; pig summary = Clinical development of the COVID-19 vaccine candidate ChAdOx1 nCoV-19, a replication-deficient simian adenoviral vector expressing the full-length SARS-CoV-2 spike (S) protein was initiated in April 2020 following non-human primate studies using a single immunisation. Whilst a single dose induced antigen-specific antibody and T cells responses, a booster immunisation enhanced antibody responses, particularly in pigs, with a significant increase in SARS-CoV-2 neutralising titres. Analysis of SARS-CoV-2 S protein-specific murine splenocyte responses by IFNγ ELISpot assay showed no statistically significant difference between the prime-only and primeboost vaccination regimens, in either strain of mouse ( Figure 1A ).

Short pregnancy, short generation interval, and high litter size make the production of transgenic pigs less time-consuming in comparison with other livestock species This review describes genetically modified pigs used for biomedical research and the future challenges and perspectives for the use of the swine animal models. It was demonstrated that precise integration of the human CFTR gene at a porcine safe harbor locus through CRISPR/Cas9-induced HDR-mediated knock-in allowed the achievement of persistent in vitro expression of the transgene in transduced cells. The study showed that multiple genetically modified porcine hearts were protected from complement activation and myocardial natural killer cell infiltration in an ex vivo perfusion model with human blood [86] .

IPA analysis software was used to analyze the cell localization, molecular function, signal pathway, regulatory network, and upstream regulators of these DEPs, which laid the foundation to elucidate mechanism of heat stress and stress-induced immunosuppression. β-tubulin was one of the DEPs identified in this study, and its expression was approximately 2.2-fold up-regulated in adrenal tissue under heat stress, suggesting that differentially expressed cytoskeletal proteins could promote stress response in the adrenal gland. doi = 10.1016/j.rvsc.2018.11.004 id = cord-003640-psnec2qp author = Mbareche, Hamza title = Bioaerosols Play a Major Role in the Nasopharyngeal Microbiota Content in Agricultural Environment date = 2019-04-16 keywords = air; control; farmer; non; pig; sample summary = doi = 10.3390/ijerph16081375 id = cord-302155-hksmt48i author = McLean, Rebecca K. title = Vaccine Development for Nipah Virus Infection in Pigs date = 2019-02-04 keywords = Malaysia; Nipah; pig; vaccine summary = Despite the importance of NiV as an emerging disease with the potential for pandemic, no vaccines, or therapeutics are currently approved for human or livestock use. Vaccine efficacy studies in animal models aim to identify specific vaccine-induced correlates of protection including neutralizing antibodies or cell-mediated responses (53) . On the other hand, pigs have been used successfully as models to study many human infectious diseases (57) (58) (59) (60) (61) (62) (63) , including NiV infection (64) . There is also a growing appreciation that pigs provide a superior animal model for influenza A virus infection and immunity and should play a more prominent role as a model for human influenza vaccine development (65) . The use of non-human animal models is crucial for vaccine development against diseases such as NiV since efficacy testing in humans is impossible.

In order to answer these questions, samples from pigs infected with a Swine (H3N2) and four different non-swine-adapted H3N8 IV strains circulating in different animal species (dogs, horses, wild aquatic birds, and seals) from our previous study (16) were analyzed and innate immune responses in the respiratory tract were thoroughly investigated. In order to check IV replication in the lower respiratory tract of pigs, BALF samples collected from pigs killed at day 3, 6, and 21 were tested for gene M of the influenza A virus using a quantitative real-time PCR procedure (17) . doi = 10.3389/fvets.2017.00048 id = cord-350626-ov9fy10b author = Nazki, Salik title = Evaluation of local and systemic immune responses in pigs experimentally challenged with porcine reproductive and respiratory syndrome virus date = 2020-05-13 keywords = PRRSV; cell; pig summary = At peak viremia, the frequencies of alveolar macrophages in infected pigs were significantly decreased, whereas the monocyte-derived DC/macrophage and conventional DC frequencies were increased, and these effects coincided with the early induction of local T-cell responses and the presence of proinflammatory cytokines/chemokines in the lungs, BAL, and BLN as early as 10 dpc. In this context, the present study aimed to investigate the trend of host immune responses against PRRSV infection during disease progression and to elucidate the innate and adaptive immunological mediators modulated by the PRRSV-JA142 strain both systemically in peripheral blood and locally in the bronchoalveolar lavage, lung parenchyma and bronchial lymph nodes (BLN) of infected pigs. To observe the activation of the local adaptive immune responses by innate immune cells at the sites of replication and the persistence of PRRSV, the T-cell phenotypes in the BLN, BAL and lung parenchyma of the euthanized control and infected pigs were analysed at 10, 21, 28 and 35 dpc. doi = 10.1186/s13567-020-00789-7 id = cord-279863-5kxgu4t9 author = Oem, Jae-Ku title = Phylogenetic analysis of bovine astrovirus in Korean cattle date = 2013-11-23 keywords = Pig; cattle summary = Eleven BAstVs, four porcine astroviruses, and two deer astroviruses (DAstVs; CcAstV-1 and -2) belonged to group 1; group 2 contained two BAstVs (BAstK08–51 and BAstK10–96) with another two in group 3 (BAstK08–2 and BAstK08–53); and group 4 comprised the BAstV-NeuroS1 strain derived from a cattle brain tissue sample and an ovine astrovirus. Recently, the complete genome of a novel BAstV associated with neurological disease in cattle was sequenced, i.e., BoAstV-NeuroS1, which was phylogenetically related to an ovine astrovirus (OAstV). In the present study, nine Korean BAstVs were associated with clinical diarrhea in cattle where calves aged \1 month accounted for 77.8 % of cases (Table 1) . Recently, the BoAstV-NeuroS1 strain was detected in the brain tissues of cattle and the analysis of its genetic diversity showed that it was most closely related to the OAstV prototype, which was identified in 1977 [3] , whereas it was phylogenetically distant from a recently reported OAstV [33] and the Hong Kong BAstVs [20] . doi = 10.1007/s11262-013-1013-0 id = cord-260840-tudl9k1g author = Opriessnig, Tanja title = Effect of porcine circovirus type 2a or 2b on infection kinetics and pathogenicity of two genetically divergent strains of porcine reproductive and respiratory syndrome virus in the conventional pig model date = 2012-07-06 keywords = PCV2; PRRSV; pig summary = doi = 10.1016/j.vetmic.2012.02.010 id = cord-339178-d6f6a5ds author = Pensaert, M.

Chicken somatic cell lines have been edited to introduce changes to this gene-conferring resistance to avian leucosis virus in vitro (Lee et al., 2017) . However, as the example for avian influenza shows, host genes play an important role in other steps of the pathogen replication cycle and also provide editing targets for disease resilience or resistance. Genome editing allows integration of the disease-resistance trait into a wider selection of pigs, ensuring genetic variability and maintenance of desirable traits. (D) Resistance genes may be identified in laboratory research but not in highly bred lines, making integration into those productive animals only possible using genome editing.

The expected increase in half-life was confirmed, and CSF1-Fc administration to mice produced substantial increases in circulating monocyte and tissue macrophage numbers, at much lower doses than the native protein. Cluster 2 (Fig. 9B) , the set of genes reduced in the CSF1-Fc-treated pigs, most likely reflects the functional zonation of the liver between periportal and perivenous regions of liver lobules (8, 19, 48) and the selective proliferation of cells derived from portal progenitors that has been observed in regenerating liver (15, 34, 36) . doi = 10.1152/ajpgi.00116.2016 id = cord-257922-tbkitz7m author = Sookhoo, Jamie R.

The objectives of this study were to assess the prevalence of selected viruses, namely porcine parvovirus (PPV), transmissible gastroenteritis virus (TGEV), porcine respiratory coronavirus (PRCV), CSFV, PCV-2, PRRSV, and SwIV in the pig populations of T&T and to identify the strains of SwIV that are circulating in T&T pigs. It is, however, very important to note that some pig farms in Trinidad, and all the pigs sampled on Tobago, tested negative for PPV antibodies. doi = 10.1007/s11250-017-1299-3 id = cord-282849-ve8krq78 author = Stebler, Rosa title = Extrapolating Antibiotic Sales to Number of Treated Animals: Treatments in Pigs and Calves in Switzerland, 2011–2015 date = 2019-09-20 keywords = Switzerland; antimicrobial; number; pig summary = We converted sales data to the number of potential treatments of calves and pigs in Switzerland for the years 2011 to 2015 using animal course doses (ACD).

Additional infection challenge experiments showed that DKO pigs exhibited decreased susceptibility to porcine deltacoronavirus (PDCoV), thus offering unprecedented in vivo evidence of pAPN as one of PDCoV receptors. Through viral challenge experiments, we found that these DKO pigs exhibit complete resistance to genotype 2 PRRSV and TGEV, and exhibit decreased susceptibility to PDCoV infection. Thus, in addition to demonstrating that our DKO pigs are robustly resistant to both PRRSV and TGEV without suffering deleterious effects for production performance, our study also provides insights into ongoing controversy about the pAPN protein as a potential receptor for PDCoV infection of pigs. pAPN protospacer PAM In order to generate more DKO pigs for viral challenge experiments, we collected ear tissue samples from three piglets (#1143, #1144, and #1145) and isolated ear-derived fibroblasts. doi = 10.7554/elife.57132
