摘要: Monoclonal antibodies (MAbs) against the haemagglutinin (H), fusion protein (F) and nucleoprotein of canine distemper virus (CDV) were examined for their ability to protect mice lethal CDV infection. One MAb H two six MAbs F protected mice, protective effect anti-H being stronger than that anti-F MAbs. The showed neutralizing activity, but MAbs, which recognized same epitope, did not. Protection by correlated with cell inhibition, not complement-dependent neutralization, cytolysis or antibody-dependent cell-mediated cytotoxicity. These results suggest neutralization antibody inhibition play important roles in mechanism
