Abstract

In the given paper there are presented the results of analysis for presence in genomes of Vibrio cholerae non-O1/non-O139 strains isolated from ships' ballast water and the coastal zone of Taganrog Gulf class 1 integrons (In1) and SXT/R391 integrative conjugative elements. The intact sequence of In13'-conservative segment (qacEdelta1-sul) was detected in 3 strains (no. 33, 59, 182), whereas in strains V. cholerae no. 28 and 52 there were revealed the probable changes of target sequence (duplication and deletion, respectively). The fragment of SXT/R391 integrase IntSXT gene was detected in 7 of 10 strains tested. Group of strains no. 27, 36, 38, 117 and 59, 182 belong to 2 most common identified genotypes, while the rest isolates are characterized by unique genotypes that indicates to different source of their origins.
