Aim. The aim was to develop an integrated online and updated geographic information system (GIS) for the systematiza tion and analysis of information on V. cholerae El Tor antibiotic resistance.Material and methods. The method of serial dilutions in a dense nutrient medium (MUK 4.2.2495-09) was used to determine the sensitivity/resistance to 22 antibacterial preparations of V. cholerae O1 El Tor strains isolated from people and from aquatic environmental objects in Russia in 2005–2016. The development of the Internet version of the GIS was carried out using programming languages HTML, JavaScript and PHP and cartographic data obtained from the corporation Rostelecom (Russia) and the community OpenStreetMap.Results. A comparative analysis of the antibiotic resistance of the strains by regions of the Russian Federation and by isolation time showed an increase of strains resistant to streptomycin, ampicillin, rifampicin and furazolidone, the appearance of cultures resistant to nalidixic acid and ceftriaxone, reduced resistance to trimethoprim/sulfamethoxazole in 2012–2016 compared to 2005–2009. In the Stavropol Krai, the isolated V. cholerae O1 El Tor were characterized by resistance to furazolidone (33.3%) and trimethoprim/sulfamethoxazole (100%); in the Primorsky Krai — to ampicillin, streptomycin, rifampicin (7%), furazolidone (43%), trimethoprim/sulfamethoxazole (100%); in the Irkutsk region and Kalmykia, to ampicillin (8.3% and 11%), furazolidone and trimethoprim/sulfamethoxazole (11% and 89%).Conclusion. The GIS developed allows to collect and analyze information on the antibiotic resistance of V. cholerae O1 El Tor, and to select the strains for given properties.
