Abstract

Substantial impact of bovine viral diarrhea virus (BVDV) on the cattle industries has prompted introduction of organized control programs in many states. These programs primarily focus on identification and removal of persistently infected (PI) cattle, the main source of BVDV transmission. In addition to cattle, BVDV may infect a large number of species within the order Artiodactyla as demonstrated by seropositivity. The white-tailed deer is the most abundant wild ruminant species in North America and BVDV infection has been documented in this species. Recently, experimental inoculation of pregnant white-tailed deer resulted in the birth of a persistently infected fawn. Considering the role of PI cattle in the maintenance of BVDV within cattle populations, PI white-tailed deer that harbor and shed the virus continuously may hamper successful execution of control efforts. The objective of this study was the investigation of interspecific BVDV transmission by cohabitation of PI cattle with pregnant white-tailed deer.
