| Abstract: | The specific features of the epidemiology of meningococcal infection in organized groups have been established after comprehensive (epidemiological, microbiological and immunological) studies, evaluated from the viewpoint of the law of the autoregulation of the epidemic process. The studies have revealed the phenomenon of the adaptive biological variability of meningococci with their prolonged reservation due to the transformation of typical bacterial forms of meningococci characterized by strict serogroup specificity and typical fermentative activity into serologically and biochemically undifferentiated forms, capable of prolonged persistence in human populations. The model demonstrating the development of the epidemic process in meningococcal infection in an organized group has been worked out. |
