Aim. Analysis of results of epidemiologic monitoring of especially dangerous, natural-foci and other infectious diseases, as well as epizootologic activity of natural foci of infection on the territory of city-resort Sochi. Materials and methods. Laboratory studies of 820 samples by PCR, immune- and bacteriologic methods were carried out, among those 344 - clinical material, 12 - water from open bodies and 321 - field material. Molecular-genetic identification of 143 strains of Vibrio cholerae, isolated from open water bodies of city-resort Sochi, was carried out. Results. Circulation of causative agents of Q fever, tularemia and hemorrhagic fever with renal syndrome of Dobrava-Adler genotypes was established, as well as rickettsia of tick spotted fever group. Predomination of rotaviruses (70.9%) was detected during study of samples of clinical material in etiologic structure of sporadically emerging acute intestine infections. Relatively high temperature values of river water during summer months (from 18 to 30°C), exit of sulfide mineral waters into the riverbed, that create alkaline medium, seasonal reduction of river debit and speed of water current facilitated sustenance of contamination of water of Agura river by V. cholerae. Conclusion. Activity of natural foci of the infectious disease and contamination of Agura river by V. cholerae 01 (atoxigenic) gives evidence on the necessity of constant control of epidemiologic situation by dangerous and natural-foci infectious diseases on the territory of city-resort Sochi, as well as study regional features of their causative agents, including using genetic methods.
