Abstract: | Comparative assessment of bactericidal activity of different disinfectants against Legionella biofilms was conducted. Monospecies biofilms of 3 strains of Legionella pneumophila obtained on plastic plates in stable conditions were used as models. It has been shown that for degradation of biofilms as well as for prophylactic action of disinfectants in preventing formation of biofilms on plastic surfaces, higher concentrations of preparations were needed as compared to their bactericidal concentrations for culture of Legionella determined by method of serial dilutions. |
