To show in experiments that hormesis is observed not only on E. coli, but also on other types of bacteria, investigate hormesis under influence of microwaves on Mycobacterium, suggest an explaination of this effect and develop a mathematical model for its computer research. M. avium 104 (subsp. hominissuis) and Mycobacterium tuberculosis strains were used, and electromagnetic field (EMF) irradiation was performed using an ultrahigh-frequency (UHF) generator at frequencies equal to the resonant frequencies of torsional vibrations of DNA of the bacteria used. Computer modeling was carried out in the MATLAB package on the basis of the modified Verhulst equation. Under the action of UHF EMF in cultures of M. avium 104 (subsp. hominissuis) and Mycobacterium tuberculosis on the first cell cycle, almost the same surges of survival were observed.: for a number of bacteria, the effect of microwave EMF, resonant natural frequency of torsional vibrations of their DNA, on the first division cycle hormesis is observed, which is explained by the stabilization of dying microorganisms, which is confirmed by computer simulation.
