[Hygienic assessment of biological reservoir pollution in Eastern Siberia and the North].

The paper presents the characteristics of microbial communities in the water reservoirs of Eastern Siberia and North and their changes depending on the anthropogenic pollution and analyzes antibiotic resistance in microorganisms. The water contamination with pathogenic viruses was revealed in relation to the man-made load, which may be a criterion for assessing the epidemiological situation on the territories.

[Indications of pathogenic viruses in water of Lake Baikal and its tributaries].

The waters of 25 large rivers falling into the Baikal Lake, their mouth water areas and open Baikal Lake areas to a depth of 500 m were for the first time in the practice of researches on the Baikal Lake were investigated for markers of hepatitis A virus and rotaviruses. The investigations showed an insignificant contamination of surface waters with pathogenic viruses. The antigens of all studied viruses and high values of bacteria from the Escherichia coli group were recorded in the areas exposed to chronic man-made pollution.
