Most acute respiratory disease in humans is caused by viruses, and, similarly in cattle, viruses are blamed for the majority of cases of acute bovine respiratory disease (BRD). Viruses as etiologic agents in bovine respiratory sisease are discussed. All recognize the "Big 3", IBR, BYD, and Pl-3 as being ubiquitous bovine viruses. There are several types of evidence commonly cited to suggest that respiratory viruses are immunosuppressive.
