title: Cross reactions among serogroup B meningococci assayed by kinetic complement fixation assay.
abstract: The surface antigens of five prototype serogroup B strains were investigated by a rapid turbido-haemolytic complement fixation assay. Several cross-reactions among the serotypes were detected. It is suggested that antigenic determinants accessible for antigen-antibody interaction need not be immunogenic.
