title: MLVA typing of clinical Vibrio cholerae strains isolated during different periods of the current cholera pandemic
abstract: MLVA typing was performed for five variable loci of the 52 Vibrio cholerae El Tor biovar strains isolated before the onset and in different periods of the seventh cholera pandemic, as well as for eight strains of the classical V. cholerae biovar—the causative agent of the preceding Asiatic cholera pandemics. It has been shown that the studied strains, which differ in their molecular genetic properties and are characterized by 38 MLVA types, form seven clonal clusters. Clusters I and II were form
