[Effect of Streptomyces spheroides proteinases on the mechanism of antibacterial protection in an experiment].

The effect of Streptomyces spheroides proteinases on the process and character of the local reaction to intraperitoneal infection of mice with E. coli was studied experimentally. It was shown that administration of the proteinases promoted a decrease in the dissemination of the abdominal cavity and a more rapid elimination of the microorganisms from the infection foci.

[Mechanism of action of an exopolysaccharide from Mycobacterium cyaneum on the local cellular reaction in experimental coli infection].

A study was made of the effect of the exopolysaccharide (PS) M. cyaneum B-646 on cellular reaction in peritoneal exudate of white mice infected with E. coli.

[Effect of the chromosome markers of antibiotic resistance on the aggressiveness of Staph. epidermidis].

Elucidation of antibiotic resistance correlation with manifestation of the pathogenic properties and aggressiveness in particular is of definite importance. Because of a wide spread of antibiotic resistance among staphylococci and ever increasing in pathology the role of S. epidermidis, the changes in penetration of the internal organ tissues, activity and intensity of capture and digestion by phagocytes of S.
