Paper Abstract

We have studied photodynamic action of He-Ne laser radiation on cultures of Staphylococcus and Streptococcus anhaemolyticus been sensitized by methylene blue. The concentration of the dye was varied form 0.001 percent to 0.1 percent and radiation power density from 75 to 200 mW/cm2. Irradiated strain was put into thermostat for 24 hours, then the number of colonies was counted and analyzed.
