Detection of persistent infection with BovineViral Diarrhea Virus (BVDV) is essential for both epidemiological and clinical reasons. In addition to the classical virological methods such as virus isolation in tissue culture, ELISA and RT-PCR, immunohistochemistry of skin biopsies has become a useful and reliable tool. Assuming that the presence of BVDV antigen in skin structures is restricted to persistent infection, this method could differentiate from transient infection. In order to answer this question, 6 calves were experimentally infected orally with a non-cytopathic genotype 1 BVDV strain belonging to the subtype k.The calves developed fever, mucopurulent nasal discharge, coughing and leucopenia with relative lymphopenia. Immunohistochemistry of skin biopsies taken daily up to day 13-post infection did not reveal any evidence of BVDV infection. BVDV was, however, isolated from blood samples on cell cultures. Anti-NS3-antibody-ELISA and serum neutralization tests showed that all six calves seroconverted. We conclude that in acute BVDV infections, with genotype 1 and the subtypes found in Switzerland (b, e, h and k) viral antigen is not found in epidermal structures of the skin. In contrast, persistently infected animals test positive for BVD viral antigen by immunohistochemistry of the skin.
