title: [Comparative analysis of mechanisms of the modification of microorganism viability under the effect of UHF heating and hyperthermia].
abstract: In experiments with models of isogenic Escherichia coli strains, a comparative study was made of the effect of SHF of electromagnetic field and hyperthermia. The survival rate of bacteria was determined and, simultaneously, injuries to genetic supramolecular structures were registered through measuring the anomalous time dependence of cell lysate viscosity. The combined effects of the mixture of these factors with H2O2 microconcentrations were studied. The differences observed in their realization were attributed to the different mechanisms of action of these factors on the repair enzyme systems of the studied cells. It has been found that the effect of microwaves on microorganisms causes much severer damages to DNA that hyperthermia does.
