Abstract: Bovine viral diarrhea virus (BVDV) causes a complex of disease syndromes, which affect multiple organ systems, and has a significant negative economic impact on the global cattle industry. In cattle, BVDV infection and disease in the reproductive, respiratory and gastrointestinal tracts cause significant losses at multiple levels of production. Research has shown that bison often carry antibodies to several cattle viruses, including BVDV, which indicates exposure to those viruses. However, there is very limited knowledge concerning the development of disease in bison infected with cattle viruses. Recently, two adult bison with general unthriftiness from a captive herd were confirmed as infected with BVDV virus and a bovine bosavirus, and viral infection persisted in these bison for greater than 50 days. The overall goals of this project are to document tissue distribution of BVDV within infected bison, and to determine herd-level exposure to BVDV and bosavirus.
