[The evaluation of a monoclonal antibody panel for Lyssavirus typing in Mexico].
The purpose of this study was to evaluate the ability of a panel of eight antinucleocapsid monoclonal antibodies developed in Europe to identify different strains of rabies virus isolated from a variety of animal species from diverse geographic areas in Mexico. Fifty-one virus-positive samples of brain tissue from various animal species and humans were studied. Material from these samples was used to infect mice, whose brains were later tested by indirect immunofluorescence, using the monoclonal antibodies described above. Strains of the virus that showed antigenic variations were sent to the Pasteur Institute in Paris for confirmation of the results. No mouse brain sample showed a pattern of antigenic reactivity that indicated the presence of a Lyssavirus other than the classic rabies virus. However, four antigenic variations from serotype 1 of classic rabies were found. The panel of antibodies was judged to be useful for the rapid classification of rabies virus in Mexico. It is possible that autochthonous antigenic variations are appearing among strains circulating in that country, a scenario that could explain some of the failures observed with certain vaccines. For this reason, there is a need to produce antinucleocapsid monoclonal antibodies with strains of rabies virus indigenous to the area.
