The antigenic profile of 45 herpesviruses (44 viruses from cattle, including six reference BHV-1 strains and 15 putative BHV-1; three reference BHV-5 strains and 20 putative BHV-5) and one butfalo isolate (BuHV) were examined with a panei of monoclonal antibodies (Mabs) prepared against bovine herpesvirus antigens. Tests were performed by immunoperoxidase (IPX) on infected cell cultures, with the Mabs as primary antibodies. lmmunostaining allowed the differentiation between types 1 and 5 viruses. Ali isolates from cases of encephalitis displayed BHV-5 profiles. Four BHV-5 isolates obtained from geographically distinct áreas displayed different and highly variable IPX patterns of reactivity. Two viruses with BHV-5 antigenic profile were isolated from semen of asymptomatic bulis. The results showed that the antigenic characterization with the Mab panei employed here is useful for typing BHV-1 and BHV-5 isolates. |
