Abstract

The presence of Bovine herpesvirus 4 (BoHV-4) was investigated by several methods in 24 aborted bovine fetuses. Polymerase chain reaction (PCR) and in situ DNA hybridization proved the presence of BoHV-4 DNA in 7 (29%) of the fetuses. The BoHV-4 genome was detected in the cytoplasm of splenic lymphocytes and monocytes, and sometimes in renal tubular epithelial cells or hepatic Kupffer cells, in all 7 PCR-positive fetuses. However, BoHV-4-specific monoclonal antibody failed to detect viral antigen in the formalin-fixed, paraffin-embedded tissue samples. No bacterial pathogens were found in the tissues of the BoHV-4-positive fetuses. Fungi were detected in 1 sample, and antibody to bovine viral diarrhea virus was detected in another. These results indicate that BoHV-4 could play a role in reproductive disorders of cattle, including abortion.
