Study serologic diversity of Legionella pneumophila strains circulating in potentially dangerous water systems in Russian Federation by using an international panel of monoclonal antibodies.
Serotyping of 234 L. pneumophila strains isolated from coolers of industrial facilities and systems of hot water supply in Russian Federation in 2007 - 2011 was performed by enzyme immunoassay by using an international panel of monoclonal antibodies.
Membership of the isolated strains in 14 L. pneumophila serogroups and in 7 subgroups of serogroup 1 was established. Among the isolated cultures serogroup 1 and 6, and Oxford and Heysham subgroup strains were predominant. L. pneumophila serogroup 1 strains were predominant in cooler water, and serogroup 6--in the hot water supply systems. 7 L. pneumophila strains of the serogroup 1 were typed by monoclone MAb 3/1 associated with LPS epitope that is characteristic for the most epidemically significant legionella strains.
Typing by using international panel of monoclonal antibodies for characteristic and evaluation of epidemical significance of legionella strains being isolated form potentially dangerous water systems is the most informative and methodically accessible to a wide range of biological laboratories.
