[The epidemiology of escherichiosis at recreation areas].

A study of epidemiological and microbiological data (2073 epidemiological examinations of patients with escherichiosis and carriers of pathogenic Escherichia and microbiological examination of 2156 strains of pathogenic Escherichia) in two recreation zones with different types of industry (clean recreation zone and that with developed industry) revealed differences in the incidence of the escherichiosis morbidity and carrier state of Escherichia, age structure of patients and carriers, seasonal distribution of the patients and proportion of the serogroups of pathogenic Escherichia isolated in the zones. It is concluded that above findings are of importance for planning antiepidemic measures in case of escherichiosis.
