Journal ArticleDOI
Classification of Neisseria meningitidis group B into distinct serotypes. I. Serological typing by a microbactericidal method.
TL;DR: Differentiation of group B meningococci into distinct types will aid in epidemiological studies and in the selection of appropriate strains for vaccines against group B Meningitis group B.
Journal ArticleDOI
Classification of Neisseria meningitidis Group B into Distinct Serotypes. III. Application of a New Bactericidal-Inhibition Technique to Distribution of Serotypes among Cases and Carriers
TL;DR: The development of sensitive serologic techniques in this laboratory has enabled the subdivision of group B meningococci into 11 distinct serotypes, and a sensitive technique for bactericidal inhibition is described.
Journal ArticleDOI
Classification of Neisseria meningitidis group B into distinct serotypes. II. Extraction of type-specific antigens for serotyping by precipitin techniques.
TL;DR: Two simple, reproducible methods for serological typing of group B meningococci have been developed and will aid in epidemiological studies of meningitis, and may also be of value for selecting suitable strains for vaccine production.
Journal ArticleDOI
Classification of Neisseria meningitidis Group B into Distinct Serotypes IV. Preliminary Chemical Studies on the Nature of the Serotype Antigen
TL;DR: Group B Neisseria meningitidis has been subdivided into 11 distinct serotypes by a sensitive bactericidal inhibition technique and the identity of serotype antigens as proteins was confirmed by their sensitivity to Pronase and trypsin.
