[Bacterial antilysozyme activity and its regulation by antibiotics].

Abstract

The effect of subinhibitory doses of 25 antibiotics on the antilysozyme property of enterobacteria considered as a marker of their persistence was studied. This provided dividing the antibiotics into 3 groups: antibiotics increasing the bacterial capacity for lysozyme degradation, antibiotics indifferent with respect to this property and antibiotics decreasing it. Decreasing of the Salmonella antilysozyme activity by gentamicin under experimental conditions promoted suppression of the bacteria parasitism in Hep-2 cells. Clinical and laboratory studies on the effect of antibiotic therapy under the control of the time course of the antilysozyme property of the pathogen in patients with acute dysentery, pyelonephritis and inflammatory processes in the female genitalia showed that the use of the antibiotics increasing this property in the pathogen was not advisable which was confirmed by the absence of significant clinical improvement in the patients and necessity of prolonging the sanative period.
