[Prevalence of type III secretion system genes in cholera vibrios from different serogroups]
Abstract:
Prevalence of vcs genes coding the type III secretion system (T3SS) in cholera vibrios of different serogroups isolated in Russia and neighboring countries was studied for the first time. Virulent strains of O1 and O139 serogroups as well as toxigenic Vibrio cholerae strains of other serogroups contained no T3SS genes. Unlike mentioned strains, 29.2% of atoxigenic non O1/non O139 cholera vibrios isolated from patients in Russia and neighboring countries contained the T3SS genes cluster, which might contribute to the pathogenic properties of these strains.
