[Modifying action of oxytocin on the biological properties of the causative agents of anaerobic non-clostridial infection].

In a number of in vitro experiments the effect of oxytocin on the antilysozyme and anticomplemental activity of Propiobacterium propionicum, Bacteroides fragilis, Prevotella melaninogenica and Peptostreprtococcus anaerobius, isolated from patients with acute pyoinflammatory pleuropulmonary diseases, was studied. Antibiotic resistance dynamics of the infective agents under study to lincomycin, clindamycin, thienam, vancomycin was also detected. The inhibiting activity of oxytocin on the persistence properties of B.

[Microflora isolated in acute inflammatory pulmonary and pleural diseases].

The species composition and biological properties of microflora isolated from 42 patients with acute inflammatory pulmonary and pleural diseases were studied. A wide spectrum of aerobic and anaerobic microorganisms was detected. Infective agents causing severe course of the infectious process were found to have a high level of persistence properties.

[Microflora of the large intestine in patients with connective tissue dysplasia].

The specific features of intestinal aerobic and anaerobic intestinal microflora in children with nondifferentiated connective tissue dysplasia were under study. A high rate of dysbiotic disturbances was noted in patients with connective tissue dysplasia in comparison with healthy persons. Profound quantitative and qualitative changes in the biocenosis of the intestine were detected in patients with the pathology of the gastrointestinal tract as well as that of the locomotor system.

[Effect of bifidobacteria on the anti-lysozyme activity of enterobacteria].

The influence of the subinhibitory concentrations of bifidobacterial exometabolites on the capacity for inactivating lysozyme in pathogenic and opportunistic enterobacteria was determined. The supernatant of B. bifidum 1 suppressed antilysozyme activity (ALA) in most Klebsiella strains and in some pathogenic Escherichia coli strains, but increased ALA in some E.
