[Characteristics of the functional antigens of Neisseria meningitidis group B]

The work deals with the characterization of the functional antigens of N. meningitidis, group B. Analysis of the total extract of N. meningitidis strain B16B6 with the use of sera obtained from patients with meningococcal infection, nasopharyngitis, salmonellosis, as well as from meningococcus carriers and healthy donors, by immune blotting techniques and the affinity isolation of the functional antigens indicate that protein antigen with a molecular weight of 13-15 kd is the main common antigen inducing the formation of antibodies in patients with meningococcal infection.
