Membrane destruction of the pathogenic cocci cells in terms of low- energy EMF of SHF range action The deflection of the membrane from the balance you can associate with the occurrence of defects in the structure of membranes due to local compression in longitudinal or transverse direction.

Accidental reduction in the thickness of the membrane is of local character that should be considered as the initial phase of forming local deepening. The most recognized is the mechanism of destruction of the membrane, caused by defects in the type of transverse pores.

However, the given expressions do not give the information about how optimal is a value of the electric voltage and what exhibition time of EMF action is required for decomposition of cell membranes of pathogenic cocci.

Multiple calculations of biotropic EMF parameters for the oppression of pathogenic microorganisms The results of the study are considered to be the basis for previous determination of biotropic EMF parameters, which affect to oppress the pathogenic organisms in wounds of animal skin cover.

In addition, these results will help to develop appropriate technical requirements for making electronic equipment. The shown correspondence proves graph 5 the fact that the increase of the voltage potential at the membrane leads to a decreasing of the critical radius of pores and reducing the maximum importance of energy W.

The reduction of critical threshold power in terms of increasing the voltage potential by the external EMF leads to increasing the reliability of above-critical membrane defect.

This fact can explain the increasing probability of rupture in pathogenic microorganism membranes, which are influenced by EMF with optimal biotropic options. Reduction of critical threshold power in terms of increasing the potential by the external EMF leads to increasing the reliability of above-critical defect of the membrane. Such defect causes the rupture of the membrane because the increasing size of the defect is accompanied by a decrease in the free energy of the system.

This explains the increasing probability of membrane rupture of pathogenic microorganisms, which are influenced by EMF with optimal biotropic options. Graph 6 shows the dependence of the average lifetime of the membranes of pathogenic cocci on the difference of voltage potential on the membrane by the external EMF. When the difference between voltage potential of more than V, the lifetime of the membrane of pathogenic cocci in wounds of animal skin cover amounts up to 1 s.

The mechanism of interaction between the electromagnetic field and the microorganisms are studied with the help of theoretical exploration of distribution of these fields inside the cells of microorganisms. First of all, the scattering of a plane electromagnetic wave in biological objects that have the structure of the plane- parallel layer of animal skin cover is concerned for the sake of simplicity: the first layer is a wool cover, the second one is skin, and the third one is the muscle.

To obtain the results, the calculations of electromagnetic fields inside the infected wounds of animal skin were done. The dependence of the amplitude of the electric field on the axis of the cylinder infected skin area on the frequency of incident electromagnetic field was examined in the study.

To conclude we should note that: 1 For the calculation of the EMF distribution in wounds of animal skin cover the expressions obtained for the plane-parallel environment should be used.
