Detection and analysis of integrative conjugative elements in Vibrio spp. strains, isolated in the Volgograd region

Abstract

The presence of integrative conjugative elements (ICEs) of SXT/R391 family in different Vibrio species isolated from natural water sources in the Volgograd region in 2003 - 2014 was established. Trimethoprim (dfr18), streptomycin (strB) and sulfametoxazol (sulII) resistance genes were detected in ICEs pattern of in V. choleraenon-O1/non-O139 strains. In Vibrio spp. ICEs strains not referred to V. cholerae type there was detected another variant of dihydrofolate reductase gene - dfrA1 localized outside the main resistance cluster. The obtained results indicate to that aqueous Vibrio spp. strains may be potential reservoir of resistance genes.
