[Biological properties of Vibrio cholerae as a part of epidemiologic surveillance of cholera].

Systematic dynamic surveillance of the complex of biological properties of V. cholerae makes it possible to find out specific features of this infective agent, to improve diagnostics and to use the data thus obtained for epidemiological surveillance on cholera. The study of the complex of biological properties of V. cholerae O1, its ecological relationships and interactions give evidence to assert that microbiological aspects as one of the primary tasks in monitoring water ecosystems, as well as the necessity of surveillance on strains isolated from humans. Different properties of V. cholerae should be determined irrespective of the object, time and territory of their isolation in the process of epidemiological surveillance on cholera.
