DIFERENCIA??O ENTRE OS VíRUS DA RINOTRAQUEíTE INFECCIOSA BOVINA (BHV-1) E HERPESVíRUS DA ENCEFALITE BOVINA (BHV-5) COM ANTICORPOS MONOCLONAIS

摘要

Bovine Herpesviruses (BHV) type 1 (BHV-1) and type 5 (BHV-5) were analysed by immunoperoxidase staining with a panel of monoclonal antibodies (Mabs) prepared against BHV antigens. One of the Mabs recognized all BHV isolates tested. The remainder four mabs recognized only BHV-1 samples, including standard laboratory strains. All isolates associated with clinical cases of encephalitis (BHV-5) displayed a pattern of reactivity distinct from that of viruses isolated from syndromes associated with BHV-1 infections. The results obtained indicate that such Mabs allowed the differentiation between BHV-1 and BHV-5, with a perfect correlation between the clinical pictures and the patterns of reactivity in vitro.
