For the first time natural leptospirosis focus was revealed in the Irkutsk suburb in 2012 - 2014 during epizootological inspection of a pond-marsh complex. Total 74 small animals (14 species) were examined, specific fragments of Leptospira DNA were found in 16,2%; positive in microagglutination test results were in 1,6% of the samples. Two pathogenic Leptospira strains were isolated from tundra common shrews (Sorex tundrensis) and one isolate - from a water vole (Arvicola terrestris). Circulation of pathogenic Leptospira in a city line represents a potential risk of infection for local population that requires the planning and realization of appropriate preventive actions.
