Abstract

Aim. Certification of V. cholerae strains stored at State collection of pathogenic microorganisms and cell
cultures SCPM - Obolensk. Materials and methods. 50 V. cholerae strains were studied. Real-time PCR with
primers to genes ctxA, ctxB, ace, zot, tсpА, toxR, hlyA, rtxC, rfbO1, ompU, ompW was used. Results.
Membership of the studied strains in V. cholerae species was confirmed by molecular-biological methods. 46
strains belong to O1 serogroup, 42 of those - El Tor toxigenic, having all the virulence genes and 4 nontoxigenic
strains. A strain had ace, zot, tсpA, toxR, rtxC, hlyA, ompU genes. 2 strains had ace, toxR, rtxC,
hlyA genes, a strain had only toxR gene which is a global regulatory gene. 2 of the 4 serogroup O1 strains were
non-toxigenic and had all the virulence genes (ctxA, ctxB, ace, zot, tсpA, toxR, rtxC, hlyA, ompU). 1 nontoxigenic
strain has ace, zot, toxR, hlyA, ompU genes, and the other - toxR, hlyA genes. Conclusion. Genome
certificates of all the V. cholerae strains stored in State collection of pathogenic microorganisms and cell
cultures SCPM - Obolensk were created. Markers of epidemic threat - ctxA, ctxB, tcpA, toxR and additional
virulence genes were determined.
