title: Evaluation of bactericidal assay in serotyping Neisseria meningitidis group A.
abstract: Seventeen of 22 group A meningococcal strains were separated into four serotypes by a microbactericidal assay using group A antisera. In addition, 6 of 19 of these strains were killed by a group B antiserum and similar cidal patterns were obtained with a group C antiserum. There was little correlation between type and case or carrier isolates, or between types and geographical location.
