Pseudomonas aeruginosa multiresistant strains biofilms formation on the impact by led emission of blue and violet spectrum

The work is devoted to investigate the impact of LED emission of blue and violet spectrum on Pseudomonas aeruginosa biofilm formation in vitro. The ability to form biofilms was observed on polystyrene dishes with primary synchronization of periodic culture of studied strains. In determining the ability Pseudomonas aeruginosa on formed biofilms after exposure of LED radiation blue and violet spectra within 10 minutes found that the radiation leads to decrease the optical density of the primary biofilms in 4.8 times on the actions of violet and 3.3 times on the actions of blue spectra, and inhibits the formation of secondary biofilms in 8.6 to 10.6 times, respectively. Based on the conducted research it has been suggested to use the LED emission of blue and violet spectra as a part of a complex antimicrobial therapy of pyoinflammatory sites aimed at prevention of Pseudomonas aeruginosa colonization and extension of hospital-related infections.
