[Biofilm formation by Legionella spp. in experiment].

[Article in Russian]


Ability of biofilm formation was studied in 28 strains belonging to 12 species of Legionella. Optimal conditions for formation of biofilms were ascertained using reference strain Legionella pneumophila Philadelphia 1. Comparative assessment of the ability of Legionella spp. to form biofilms was performed by cultivation in proteosopepton broth (for 96 hours) and in water (for up to 2 weeks). Highest rates of biofilm formation were observed for strains of L. pneumophila and L. longbeachae. Between L. pneumophila strains the most prominent ability to form biofilms was observed in newly isolated strains BLR-05 and TOTAL 1. Opportunity to use different ability of Legionella species to biofilm formation as a epidemiologically significant marker and for modeling of biofilms of Legionella in association with other microorganisms was discussed.
