Their considerable number decreases along with distance within the reservoir. From the Kłodnica River estuary and in the distance 700 m, the water quality is classless (coefficient of Coli - fecal type was 0.002 - 0.008). In the 1500 m distance water quality was III and II class purification. Near the Kłodnica River estuary the number of streptococci fecal-type, rod-shaped bacteria (Clostridium) and Pseudomonas aeruginosa was big (MPN 2400). The FC/FS index (fecal coliform/fecal enterococci) was 4. It is indicative of human-fecal pollution. No diversification in the number of staphylococci depending on sample point localization was recorded. The research by traditional and the latest methods did not confirm the presence of Salmonella in the water of reservoir. The investigations of staphylococci and Pseudomonas aeruginosa seem to confirm the role of zooplankton as an important element (consumption of biocenosis feeding on bacteria pressure) in the selfpurification processes. The patho-rnicrobiological pollution of the reservoir is a factor, due to recreational function of its east part of.}, type={Artykuł}, title={The Pathogenetic Bacteria in Dam-reservoir Dzierżno Duże}, URL={http://ochroma.man.poznan.pl/Content/123859/PDF-MASTER/10_AE_VOL_28_2_2002_Smylla_Bakterie.pdf}, keywords={microbiology, pathogenous, antropopresion, dam-reservoirs}, }
