Subsequent to a previous study of border disease virus (BDV) horizontal transmission from a persistently BDV-infected calf to 6 seronegative pregnant heifers, the heifers were slaughtered 60 days after exposure to the infected calf, and their fetuses and placentas were examined. Immunohistochemical examination of fetal organs and placenta showed positive labeling of moderate intensity for pestivirus antigen in 3 of 6 heifers. BDV infection in these 3 animals was confirmed by the detection of BDV RNA in different organs using reverse transcription quantitative polymerase chain reaction. In the placenta, the positive cells were visualized mostly on the fetal side. In those 3 heifers that harbored an infected fetus, the placental tissue in the placentome region showed a moderate to severe mononuclear and fibrosing placentitis and, in severe cases, necrotic areas. The inflammatory population was composed predominantly of T and B cells, a substantial number of macrophages, and, to a lesser extent, plasma cells. This is a novel report of placentitis in persistently BDV-infected fetuses from pregnant heifers that became acutely infected by cohousing with a calf persistently infected with BDV, which extends previous reports on bovine viral diarrhea virus-infected and BDV-infected cattle and sheep, respectively.
