[The serosubtyping of serogroup B meningococci].

The results of the study of 116 Neisseria meningitidis strains, isolated from patients at different territories of Russia at the period of 1983-1992, by the method of the enzyme immunoassay are presented. 13.8 +/- 3.2% of the strains were found to have stereotype proteins and 59.5 +/- 4.5%, subtype proteins. In the population of circulating meningococcal strains no absolute prevalence of any single serotype or subtype was established. The comparison of the tendency in the course of morbidity rate and the state of the serosubtype composition of isolated group B N. meningitidis stains is indicative of the favorable situation with respect to meningococcal infection and the importance of further observation of the circulating strains.
