Abstract
Results of the investigation of the species composition and distribution of the bacteria of Enterococcus genus in the water of Lake Baikal are presented, the degree of stability to antibiotics is also described. It is demonstrated that these bacteria live in the littoral regiosn of the lake. The microorganisms under investigation were not detected in the deep-water part of the lake. The number of isolated strains is 120, they were identified as E. faecium, E. avium, E. faecalis, E. mundii, E. hirae, E. durans, E. gallinаrum. In general, the enterococcus strains isolated from the water of Lake Baikal are characterized as sensitive to antibiotics. Nevertheless, enterococcus strains stable to antibiotics were isolated from the collection under investigation, including the strains for which an intermediate level of stability to vancomycin is characteristic.
