The specific features of Legionella colonization of water supply systems were studied in the large healthcare facilities (HCF) of Moscow. Examination of 16 buildings of 5 Moscow multidisciplinary HCFs, including their risk-group units, revealed the high level (68%) of Legionella pneumophila contamination of hot water supply systems. Among the Legionella pneumophila strains circulating in the hot water supply systems of Moscow HCFs, there was a preponderance of its serogroup 6 (44%), 5 (26%), and 1 (13%) strains. The findings suggest that it is necessary to arrange a set of prophylactic measures for microbiological monitoring and protection of water systems in the HCFs, which are aimed at preventing nosocomial legionellosis.
