Abstract

Infection of pregnant dams with bovine viral diarrhea virus (BVDV) during the first trimester of gestation can result in the establishment of a persistent infection in the fetus and BVDV is then constitutively shed by the persistently infected (Pl) calf. PI cattle have been identified as a major reservoir for the virus. BVDV control and eradication efforts focus on the detection and removal of PI animals from herds. This study describes the epidemiological, clinical, and pathological features of an isolated outbreak of BVDV infection in a South Dakota cattle herd in 2003.
