Introduction

Control of Bovine Viral Diarrhea Virus (BVDV) relies on accurate identification of persistently infected (PI) animals. A persistent infection can develop when a fetus is exposed to virus in utero, prior to 125 days gestation. While effective tests exist to identify PI calves and cattle, none of them determine the BVDV status of a pregnant cow's fetus. Thus, a pregnant, non-infected cow may still introduce BVDV to a herd by delivering a PI calf. This study evaluated different virological tests on amniotic and allantoic fluid from bovine fetuses for detection of BVDV.
