[Influence of the food products, enriched with pectin, on properties of potentially patogenic representatives of the microflora of the large intenstine].

The treatment method of disbios suffered by patients with syndrome of irritated intestines with constipations was under research. The method was based on introduction of sour-milk beverage with addition of beet pectin in a dietary intake. The comparison product was kefir. The following developments were detected against the positive dynamics of clinical symptoms: improvement of microbiocenosis structure, reduction of potentially pathogenic germs, inhibition of pathogenic properties of enterotoxigenic Staphylococcus aureus. Comparison group results showed lower clinical efficiency and poorer effect of dietary treatment on large gut microorganisms, contents of enterotoxigenic S. aureus remained unchanged. Introduction of sour-milk beverage with addition of alimentary fibre in a dietary intake of patients suffering the syndrome of irritated intestines with constipations was found expedient.

[Effect of erithriol on intestinal microflora and morphology of rat internal organs].

In experiences on rats is shown, that 22 daily upkeeping of animals on a diet including eritrit in a dose 1 g/weight of a body, do not cause any changes from the party intestinal microflora and morphological structure of internal bodies. However, the specified doze eritrit causes statistically authentic increase of levels conditionally-pathogenic anaerobius of the representatives microflora, first of all staphylococcus and citratessimilation enterobacteria.

[Enterotoxin production as a diagnostic test in intestinal dysbacterioses ].

The new approach to advancing diagnostic of dysbacterioses grounded on determination of the pathogenic factors of potential-pathogenic microflora is proposed. The method of reacting of an indirect hemagglutination with usage of erythrocital diagnosticums ostend availability of production of staphylococcal enterotoxines of types A and B in 40% of the strains of staphylococcuses, isolated at dysbacterioses. The intensity of production of staphylococcal enterotoxines for strains of microorganisms, isolated at dysbacterioses and carrying of S. aureus, and at food borne diseases, is various. The availability of clinical developments of an intestinal dysfunction in faeces of the patients contacts with persistence of enterotoxigenics S. aureus, and their elimination--with successful police of the disturbed microbiocenosis.

[Comparative study of the effects of different sour milk products on the intestinal microflora of healthy infants].

Our study was aimed to investigate in comparable conditions the composition of intestinal microflora of healthy infants who were given 9 types of fermented milk products. There were observed 103 practically healthy infants aged from 4 month to 1,5 years old. The obtained data have shown that studied products improve intestinal microflora in infants. Significant increase of bifidobacteria in infants intestines was promoted by fermented milk products containing alive bifidobacteria with rather high acidity. The most of products which contain bifidobacteria decreased the level of hemolisinproducing Escherichia coli and coagulase-positive staphylococcus. The products which not contain bifidobacteria decreased the level of Candida albicans and protei.

[A micromethod for the rapid detection of proteolytic activity of microorganisms].

The author has developed a micromodification of the rapid photoemulsion method for the detection of the microorganism proteolytic activity. The test is carried out on polystyrene plates, meat-peptone broth is used as the suspension fluid. Rectangular film strips are vertically placed into the wells, thus preventing false-negative reactions possible in case of an erroneous horizontal position of the film with the emulsion layer turned upwards if square or round film fragments are used. The proteolytic activities of 120 microorganism strains (95 of these hydrolyze gelatin) have been examined by the micromethod and the routine test with gelatin. The suggested test is 2-4-fold more rapid than the routine one used in investigations of the cultures slowly hydrolyzing gelatin. The fact that the test is carried out on the plates considerably reduces the nutrient medium and the number of laboratory glassware and helps obtain more accurate results.
