title: [Changes in the electrical characteristics of bacterial cells in the disruption of the barrier function of the cytoplasmic membrane].
abstract: A change in the electro-orientation spectrum followed by a change in the electric characteristics of bacterial cells had been measured when the barrier function of the cytoplasmic membrane was disordered under the action of damaging physical and chemical factors. Analysis of changes in the spectra at a frequency of 10(4) to 10(7) Hz allows one to estimate the degree of cell damage in quantitative terms. The paper presents the results of comparing three procedures for such an estimation: inoculation onto solid growth media; linear regression analysis of an electro-orientation spectrum; comparison of the electro-orientation effect at a high frequency (ca. 5 X 10(5) Hz) and at a medium frequency (ca. 10(4) Hz).
