title: Monoclonal antibody-based immunohistochemical detection of bovine viral diarrhea virus in formalin-fixed, paraffin-embedded tissues.
abstract: Thirty-two monoclonal antibodies directed against epitopes on bovine viral diarrhea virus proteins and glycoproteins were tested for immunohistochemical reactivity with bovine viral diarrhea virus in formalin-fixed and paraffin-embedded tissues from 45 cases of bovine viral diarrhea virus-associated mucosal disease. Only one antibody, designated 15C5, which reacts with the 48-kD glycoprotein of bovine viral diarrhea virus, detected an epitope preserved in these specimens. Monoclonal antibody 15C5 and a polyclonal antibody to bovine viral diarrhea virus successfully detected bovine viral diarrhea viral antigens in 44/45 cases of mucosal disease and did not react with formalin-fixed tissues from 30 uninfected cattle. Monoclonal antibody-based immunohistochemical detection of bovine viral diarrhea virus is routinely fixed tissue specimens has advantages over other currently available techniques in terms of the convenience of specimen submission, the relative ease of method standardization, and the rapidity of the test, and by enabling identification of the virus in association with specific tissues, cell types, and histologic lesions.
