[Characteristics of the meningococcal carrier state in organized collectives and its role in the development of generalized forms of meningococcal infection].

Complex (epidemiological and bacteriological) investigations of the level and structure of meningococcal carriership among the members of organized collective bodies differing in the epidemiological situation with respect to meningococcal infection have been carried out. The absence of differences between the total level of meningococcal carriership and the morbidity rate with respect to the generalized forms of meningococcal infection has been shown. The presence of cases of meningococcal meningitis in the groups under study has been found to depend on the intensity of the circulation of certain meningococcal serogroups. The possibility of the ecological reservation of the causative agents of meningococcal infection as polyagglutinable forms has been suggested.
