Epidemiological and microbiological characteristics of meningococcal infection in Kazan

Abstract

Observations of the epidemiological process of meningococcal infection over the past 10 years on the scale of a large city and its districts made it possible to note a decrease and subsequent stabilization of the incidence; to identify differences in the course of the epidemiological process in the city districts characterized by population migration, social, demographic and other characteristics. In addition to other epidemiological features inherent in the period of decline in incidence, changes in the pathogenic properties of pathogens were found. It is recommended, along with other markers of bacteriological surveillance of meningococcal infection, to use the assessment of the cytopathogenicity of the latter by their effect on the cell culture.
