The current stage of development of the seventh pandemic of cholera in the world is characterized by a tendency to widespread, registration of outbreaks, epidemics and sporadic cases of diseases associated with drifts, including single drifts of this infection (without spreading) into Russia. The territory of Russia is one of the most water-supplied countries in the world; however, some of the rivers, such as the Volga, Ob, Amur, and Don are among the most important economic arteries, therefore just these rivers were the objects of study for this work. A comparative multivariate analysis of data from long-term monitoring studies on cholera showed that in all the studied reservoirs during the study period there was observed the isolation of cultures of Vibrio cholerae with diverse phenotypic characteristics. The data obtained allows us to tentatively assume that in Russia there are a number of areas with aquatic ecosystems, such as r. Volga, Ob, Amur, and Don, in which non-toxic cholera vibrios can survive during the summer period. In the microbiological aspect of cholera epidemiological surveillance, the accumulation of long-term data on the circulation of Vibrio cholera strains in environmental objects is important. From our point of view, the use of computer technologies (Geoinformational System) for analyzing the dynamics of the isolation of V. cholerae cultures in both spatial and temporal formats contributes to the timely determination of the direction and volume of preventive measures in each specific administrative territory of the country.
