Abstract
Hybrid cell lines producing monoclonal antibodies against the O-antigenic determinants of Vibrio cholerae O:1 have been established. The specificity of the antibodies was ascertained by enzyme-linked immunosorbent assay inhibition experiments by using lipopolysaccharides from V. cholerae O:1 strains and type strains of groups O:2 and O:21. The anti-A antibody was of the immunoglobulin M (IgM) class, whereas the anti-B and -C antibodies were IgG3. The antibodies had a good agglutinating capacity when tested against V. cholerae O:1 strains in the slide agglutination test.
