title: [Retrospective VNTR-analysis of genotypes of Vibrio cholerae 01 strains isolated, during the 7th cholera pandemic, in Rostov Region].
abstract: Antiplague Research Institute, Rostov-on-Don, Russia Retrospective multi-locus VNTR-analysis was made for 166 Vibrio cholerae strains isolated, 1967-2001, in Rostov Region from clinical samples (82 strains) and from water samples (84 strains). On the basis of cluster analysis of heterogeneous identification strain genotypes, 45 variations of individual strains were shared between 11 separate clusters, among which the F cluster vibrios were predominant. Having emerged, 1970, in the region, they were widely spread during the 1973-1975 cholera pandemic and were registered, among the isolated strains, till 1992 indicating the possibility of long persistence of V. cholerae 01 in the natural aquatic environment. Presumably, the ecosystem specificity contributed to the long-term vibrio persistence.
