THE COMPARATIVE CHARACTERISTIC OF ANTIBACTERIAL ACTIVITY OF SELENOORGANIC COMPOUNDS ON CLINICAL STRAINS OF STAPHYLOCOCCUS AUREUS

Antibacterial activity of diacetophenonylselinide (a compound 1) and its nitroderivative (a compound 2) on ten clinical strains of Staphylococcus aureus is studied. Much higher antibacterial activity of the compound 2 which in concentration of 0,01 mg/ml at various time of influence causes destruction of 10,6-69,2 % of bacterial cells in comparison with the control is found out.

Photodynamic Effect of Red Laser Radiation on the Growth of Staphylococcus aureus Strains with the Use of Photoditazine

The influence of red laser irradiation on the growth of colonies of Staphylococcus aureus and photodynamic effect of the photosensi- tizer Photoditazin were performed. It is established that the radiation of a semiconductor red laser (? = 660 nm, 100 mW/cm2.) has a direct bacteriostatic effect on the growth of S. aureus. This effect on the standard strain is manifested only when relatively high doses are used (180 J/cm2). Inhibition of bacterial growth reaches 36%.
