Materials and methods. A total of 105 nontoxigenic El Tor vibrio cholerae strains selected applying the geographic information systems (GIS) were used. PCR typing of the strains was performed by the previously developed procedure. The findings were statistically processed according to the STATISTIKA computer program (StatSoftRussia).
Results. The investigation showed variability in V. cholerae O1 El Tor strains by phage lysability. It established the genetic diversity of V. cholerae isolates. The investigators revealed V. cholerae strains included in the cluster found only in the Republic of Kalmykia and in the Rostov Region. The presence of this set of genetic determinants suggested that water basins could be considered as a reservoir of pathogenicity/persistence genes.
Conclusion. The aquatic ecosystems of the Republic of Kalmykia were ascertained to have the most favorable conditions for survival of nontoxigenic V. cholerae O1 El Tor strains in them for a few years, without excluding new drifts.
