Abstract

The affect of preliminary irradiation of staphylococcus culture by electromagnetic radiation of extremely high frequency (42, 54, 66 + 78 GHz) of nonthermal intensity on the bacteria growth on the media containing various antibiotics is studied. The reliable change in bacteria sensitivity toward 5 antibiotics, mainly having membranotropic properties is observed in the experiments using 14 antibiotics with various mechanisms of action. It has been established that in the presence of subbactericide concentrations of active antibiotics the irradiation could result in both further suppression of bacteria growth and its stimulation. As shown, the development of these effects takes place even in a matter of minutes of preliminary irradiation, and weak changes are observed at further increase of this period up to 60 min.
