In the paper there is presented a characteristics of antibiotic-resistant strains of Vibrio cholerae, isolated in the Volgograd region during the period of 1980-2000. There were studied cultural and morphological properties of the isolates, their biochemical activity, resistance to antibiotics of different classes, there was performed the detection of virulence genes and sequences of transmissible SXT-element. There was demonstrated the presence of different types of SXT in the content of the genome of the examined strains - SXTMO10 element with cluster of the antibiotic resistance gene sulII-strB-dfr18, SXTET element carrying the sequences sulII dfrA1, and not having a resistance gene to aminoglycosides strB, and SXTS element with deleted cluster of antibiotic resistance genes.
