Abstract

The complication of cholera epidemic situation in Ukraine (2011) caused the reinforcement measures on monitoring Vibrio cholerae in seawater in Taganrog Bay in the framework of measures for prevention of the spread of infection over the territory of the Rostov region and the country. Phenotypic and genotypic features of 3 selected atoxigenic strains of Vibrio cholerae eltor O1 and 1 toxigenic strain of V. cholerae eltor Inaba № 301, containing the hybrid prophage were characterized. With great probability there was established the absence of association of this strain with the outbreak of infection within the territory of the neighboring country, but there was revealed his relationship with to imported strains (1999, 2005). Atoxigenic strains were similar to strains previously detected in water bodies of the Rostov region. The implementation of the set of measures for the strengthening of epidemiological control permitted to prevent the importation of infection into the territory of the Russian Federation in 2011 - 2012.
