Abstract

Photodynamic therapy (PDT) now is widespread for treatment of the various skin infections caused by Propionibacterium acnes or Staphylococcii spp. We used PDT for influence on opportunistic microflora of human skin presented by Staphylococcus hominis, S. warnery, S. epidermidis S. aureus 209 P, S. aureus 69. Species S. epidermidis, S. aureus 209 P, S. hominis to some extent reduced colonies forming ability under action of dual wavelength LED-light (442 nm and 597 nm). For species S. warnery, S. aureus 69 the increase in CFU number under action of light relative to control was characteristic. Our experiments have shown, that phototherapy can be used for treatment of diseases associated with S. aureus 209 P. The doze 8 J/cm² caused reduction in CFU of this species on 40% relative to control.
