Total Viable Count at 20°C (TYC 20°C) and Total Viable Count at 37°C (TYC 37°C) were used as indicators of pollution, while Total Coli (TC), Faecal Coli (FC) and Faecal Streptococcus-Enterococcus (FS) - as indicators of the sanitary state. Water samples were collected from 3 sites situated in the centre of the lake. Pelagial and profundal waters showed a little degree of pollution. Higher bacteriological pollution was found in some of waters samples from Lake Wigry at site I in the vicinity of the mouth of the Czarna Hańcza River. The most numerous sanitary microorganisms were detected at the deep from I to 5 meters and above the bottom sediments. Number of FC bacteria was only higher at the depth of 5 meters and deeper. An important positive correlation was noted between temperature and TYC 20°C as well as TYC 37°C, while negative between TC also FC during the whole study period. The oxygen content was correlated negative with TYC 20°C, TYC 37°C and FS. The depth was correlated negatively with TYC 20°C only.}, type={Artykuł}, title={Vertical Distribution of Sanitary Microorganisms and The Thermal-Oxygen Relations in Pelagial and Profundal Waters of Wigry Lake}, URL={http://www.journals.pan.pl/Content/123636/PDF/4_AE_VOL_30_3_2004_Korzeniewska_Pionowe.pdf}, keywords={lake, water, indicatory microorganisms, thermal-oxygen relation}, }
