Influence of laserirr adiation of staphylococcus aureus culture on minimal inhibitory concentration of some antibacterial drugs
Abstract
The article shows the research results of low-intensive laser radiation with 635 and 870 nm wavelengths on the Staphylococcus aureus clinical isolates sensitivity and also collection S. aureus ATCC 29213 test-strain to the different groups of antibacterial drugs by the serial macro dilutions method in a liquid nutrient medium. The results indicate a significant sensitivity increase to antibiotics (penicillin group of semi-synthetic antibiotics, cephalosporins, aminoglycosides, tetracyclines) of irradiated Staphylococcus aureus cultures. During the irradiation of all Staphylococcus aureus strains, MIC of all investigated antimicrobial drugs has decreased by 2-4 times in comparison with control series of experiments in which unirradiated cultures have been used.
