V. parahaemolyticus and V. alginolyticus strains isolated from patients during an outbreak of an acute enteric disease in Vladivostok in 1997 were studied. All strains were found to possess typical taxonomic signs. V. parahaemolyticus isolated from humans had direct heat stable haemolysin exotoxin. The overwhelming majority of these strains belonged to(More)
Cases of cholera were registered in Daghestan in all pandemics with the exception of the fourth one. For the first time the import this infection by pilgrims returning from their hajj by motor transport and traveling through the countries of southwest Asia was registered. 184 settlements of 27 regions, 8 towns and 1 housing estate were involved in the(More)
Results of analysis of cholera outbreak during which V. cholerae O1 biovar El-Tor ctxAB- tcpA+ was isolated from 2 patients and 30 carriers are presented. Epidemic was caused by contamination of water source and water route of transmission. Strains identical to ones detected in humans were isolated from water of surface well in zone of water intake. Genome(More)
Retrospective analysis of epidemic cholera manifestations was made in Daghestan using the data of operative epidemic analysis of the break in 1994. Unexpected prolongation of epidemic process of cholera for Daghestan, which was imported by pilgrims from Southern-Western Asia, has been shown using climate-geographical social-demographical and(More)
The review presents data on circulation of antibiotic resistant and susceptible strains of Vibrio cholerae serogroups O1 and O139 isolated from cholera patients and healthy persons as well as from the environment, in Asia, Africa, Australia, and Europe (including New Independent States) during 7th cholera pandemic.
The worldwide epidemiological situation in cholera El Tor at the beginning of this century is presented; among its characteristic features are continued extensive epidemics and outbreaks in African and Asian countries with cases of import of this infection to other continents. Outbreaks caused by a new variant of the infective agent of cholera, Vibrio(More)
The in vitro study of the adhesive properties of V. cholerae eltor and V. cholerae O139 on a model of mammalian red blood cells revealed a correlation of their adhesive properties, the presence of the ctx AB, tcpA genes, and their hemolytic activity when blood group A (II) red blood cells were used. In the latter case, the strains having the characteristics(More)
Mechanisms of realization of Vibrio cholerae hemolytic activitywere analyzed using summarized own results and data from the literature. It has been shown that lectin receptor, which coded by hlyA gene, participates in lysis of sheep erythrocytes, but not of rabbit erythrocytes, as well as interact with D-galactose with selectivity to 3 anomers.
