Abstract
The aim of the work was to analyze the monitoring data on contamination of water bodies with Vibrio cholerae О1 during epidemiological surveillance of cholera in Russia.
Materials and methods. The analysis of the data on the isolation of cholera vibrios O1 from water bodies (2015–2024) was carried out using official statistical reports from the Rospotrebnadzor Administrations in the constituent entities of the Russian Federation and anti-plague institutions. Studies of biological properties of the strains were performed in accordance with MR 4.2.3745-22; genome-wide sequencing was conducted on the MiSeg platform (Illumna, USA).
Results and discussion. Information about 848 strains of V. cholerae O1, including V. cholerae O1 ctxА+tcpA+ (3), V. cholerae O1 ctxA– tcpA+ (48) and V. cholerae O1 ctxA– tcpA– (797) in 30 entities of the Russian Federation has been investigated. V. cholerae O1 El Tor ctxA– tcpА– and V. cholerae O1 El Tor ctxA– tcpA+ were isolated from 72 water bodies: 46 rivers, 13 ponds, 8 lakes, and other objects in various climatic regions, mainly in the Atlantic-continental European (forest) part, as well as in the continental East Siberian and monsoon Far Eastern areas. The data on contamination of water bodies with V. cholerae O1 in the administrative territories of the Russian Federation, varying by types of epidemic manifestations of cholera, federal districts; sampling points; on the results of epidemiological investigations using genome-wide sequencing of V. cholerae O1 ctxA– tcpА– strains are provided in the paper.
