Bovine viral diarrhea virus 2:

A species of PESTIVIRUS causing systemic infections including BOVINE VIRUS DIARRHEA-MUCOSAL DISEASE and Bovine Hemorrhagic Disease (HEMORRHAGIC DISEASE, BOVINE) in cattle and some other cloven-hoofed animals. There are several strains and two biotypes: cytopathic (rare) and non-cytopathic. The severity of disease appears to be strain dependent. Cytopathogenic effects do not correlate with virulence as non-cytopathic BVDV-2 is associated only with Hemorrhagic Disease, Bovine.
