Microbial diversity involved in the etiology of a bovine respiratory disease outbreak in a dairy calf rearing unit	2020-05-11		.txt	text/plain	4024	190	49	The etiological agents involved in a bovine respiratory disease (BRD) outbreak were investigated in a dairy heifer calf rearing unit from southern Brazil. A battery of PCR assays was performed to detect the most common viruses and bacteria associated with BRD, such as bovine viral diarrhea virus (BVDV), bovine respiratory syncytial virus (BRSV), bovine alphaherpesvirus 1 (BoHV-1), bovine coronavirus (BCoV), bovine parainfluenza virus 3 (BPIV-3), Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Mycoplasma bovis. The present study reports a molecular diagnostic survey for multiple etiological agents during an outbreak of BRD in heifer calves in a Brazilian dairy calf rearing unit. In this study, the findings of 85.7% positive BALF samples for at least one of the pathogens associated with BRD highlight the importance of this disease in the calf rearing unit, especially of the mixed infections that were more frequent (72.2%) than single infections (27.7%).	./cache/cord-277545-xyhh7uky.txt	./txt/cord-277545-xyhh7uky.txt
