[Monitoring of bacterial contamination of water reservoirs in the Rostov region].
The paper estimates the epidemic value of indicators for microbial contamination of waters from their main supply sources (waters from the Tsimlyansk Reservoir and the Nizhni Don River and drinking waters from the towns of Azov and Tsimlyansk) in the Rostov Region. The Tsimlyansk Reservoir water met the SanPiN 2.1.5.980-00 requirements for the normalizable indices of total coliform bacteria (TCB) and thermotolerant coliform bacteria (TtCB) in 54% of the samples; glucose-positive coliform bacteria (GPCB) and Salmonella were isolated in 100 and 60%, respectively. The Azov drinking water that met the SanPiN 2.1.4.1074-01 requirements for TCB and TtCB) was found to contain GPCB, Klebsiella, and Pseudomonas aeruginosa in 5.7, 4.8, and 3% of the samples, respectively Direct detection of pathogenic and potentially pathogenic microorganisms and the integral GPCB index are of the greatest prognostic value in assessing a microbial risk for waterborne enteric infections.

[Biosafety at the railway transport objects of the Russian Federation].
The results of a microbiological investigation of drinking water quality were analyzed. Water samples taken from the centralized and noncentralized water supply sources failed to meet hygienic standards in 14-18% of cases and those from water tubes did in 4-6%. ⋯ L. pneumophila strains were isolated from the drinking water of railway carriages. Proposals are given to improve railway sociohygienic monitoring.
