Abstract

The paper presents the results of a study of the antibacterial properties of monochromatic incoherent light with wavelengths of 635 nm with an average power of 50 mW, a density of 5 J / cm2 and 450 nm with an average power of 50 mW, an energy density of 5 J / cm2 , the area of the illuminated zone – 9.25 cm2 , illumination – 11 mW / cm2 in vitro using Staphylococcus aureus strains isolated from the skin of patients with staphylococcal skin lesions, the exposure time to the isolates of microorganisms is 900 seconds, the area of the illuminated zone is 9.25 cm2 , the illumination is 11 mW / cm2 . It was established that light with a wavelength of 635 ± 10 nm has poorly pronounced bacteriostatic effects on Staphylococcus aureus, which was confirmed by the growth of Staphylococcus aureus in isolates after irradiation, light with a wavelength of 450 ± 10 nm, has bacteriostatic properties, which was confirmed by a decrease in the number of Staphylococcus aureus colonies after exposure to light with a wavelength of 450 ± 10 nm.
