Abstract
Purpose. To study evident abilities of low-intensity red laser light with wavelength 660 μm to inhibit the growth of various strains of Staphylococcus aureus. Materials and methods. Methicillin-sensitive and methicillin-resistant strains of Staphylococcus aureus were used as studied objects. Semiconductor laser generating linear polarized light in the red spectral region (X - 660 nm) was used for irradiation. Power density was 100 mW/cm2, exposure time - 5, 10, 15 and 30 min, heat density was 30, 60, 90 and 180 J/cm2, respectively. Results. It has been found out that low-intensity laser radiation has an inhibitory effect at the growth of both methicillin-sensitive and methicillin-resistant strains of Staphylococcus aureus. The resistant strain is more sensitive to red laser light as the bacteriostatic effect is seen at lower doses.
