INFLUENCE OF MILLIMETER WAVES OF NONTHERM AL INTENSITY ON THE SENSITIVITY OF STAPHYLOCOCCUS TO VARIOUS ANTIBIOTICS

The affect of preliminary irradiation of staphylococcus culture by ele ctromagnetic radiation of extremely high frequency (42, 54, 66 divided by 78 GHz) of nonthermal intensity on the bacteria growth on the medi a containing various antibiotics is studied. The reliable change in ba cteria sensitivity toward 5 antibiotics, mainly having membranotropic properties is observed in the experiments using 14 antibiotics with va rious mechanisms of action. It has been established that in the presen ce of subbactericide concentrations of active antibiotics the irradiat ion could result in both further suppression of bacteria growth and it s stimulation. As shown, the development of these effects takes place even in a matter of minutes of preliminary irradiation, and weak chang es are observed at further increase of this period up to 60 min.
