BVD virus
BTV and closely related EHD of deer
The FAD BTV serotype 8
Other: Bovine leukemia virus
Component of BRD complex/shipping fever, not really associated with severe disease, but sets stage for secondary viral infections
can infect sheep/goats too
Parainfluenza Virus 3 (PI3)
paramyxoviridae,
Important respiratory pathogen of ruminants and humans, can cause disease outright or contribute to BRD complex, occurs mostly in the fall, pathogensis associated with IgE
Bovine Respiratory Syncytial Virus
Paramyxoviridae
viral infection of upper/lower resp tract, can also cause abortion, coital exanthema, posthitis, conjuntivitis, gastroenteritis, sometimes encephlalitis, also called “red nose”
can also infect small rmts
may see eroisons in the digestive tract
