nThe results of the serotyping of 244 V.cholerae non O1/O139 cultures isolated from patients in Uzbekistan in 2000 and 2001 are presented. All isolates were studied by the method of molecular probing and in the polymerase chain reaction for the presence of virulence genes and for sensitivity to phages ctx+, ctx- and hemolytic activity. The use of monoreceptor O-sera O2 — O83 made it possible to determine vibrios of 32 serogroups with the dominating role in the etiology of acute enteric diseases belonging to serogroups O18, O62, O82, O37. Genes ctx AB were detected in none of the isolates, 5 of them contained gene tcp A. A group of cultures, sensitive to phage ctx+ and belonging mainly to enteropathogenic serogroups, was detected.
