[Correction of intestinal dysbacteriosis in elderly patients with the use of bifidobacterin introduced by different routes].

The results of the correction of disturbances in intestinal microflora in elderly patients with the use of bifidumbacterin in the form of powder or suppositories are presented. The effectiveness of the rectal administration of bifidumbacterin (by microinjections through an enema or in suppositories) is shown in comparison with the oral administration of the preparation. The administration of bifidumbacterin in suppositories for 15 days resulted in decreased content of hemolytic Escherichia below the threshold of determination in all examined patients.

A method for estimation of urease activity in gastric mucosa biopsy specimens and Helicobacter pylori cell suspensions.

A method for measuring urease activity in biopsy specimens and Helicobacter pylori cultures from these specimens is proposed. The method is based on measurement (with a portable pH-meter) of the rate of pH changes in a reaction mixture consisting of buffer, substrate (urea), and biopsy specimen or bacterial cells. This method revealed that urease activity of biopsy specimens correlated with that of H.

[The microbiological characteristics of intestinal dysbacteriosis in children and adults in the city of Moscow].

The bacteriological analysis of 302 children has revealed that dysbacteriosis with the increased content of hemolytic Escherichia in the intestine develops more frequently in the presence of the deficiency of bifido- and lactobacteria. The development of other kinds of dysbacteriosis with the increased content of different opportunistic enterobacteria, staphylococci, enterococci and fungi, as well as dysbacteriosis with the decreased content of Escherichia, does not practically depend on the deficiency of bifido- and lactobacteria. In patients with the increased content of Escherichia an increase in the content of opportunistic enterobacteria, staphylococci and fungi is observed more frequently than in patients with the low content of Escherichia.

[The antigen-specific activity of a multicomponent vaccine administered orally and subcutaneously].

The antigen-specific activity of polycomponent vaccine VP-4 consisting of Klebsiella pneumoniae, Staphylococcus aureus, Proteus vulgaris and Escherichia coli antigens was studied. The same form of the vaccine was used for both subcutaneous injection and oral administration.

[The specific activity of a multicomponent vaccine made from the antigens of opportunistic microorganisms].

Multicomponent vaccine prepared from the antigens of 4 representatives of opportunistic microflora possesses high specific activity. The passive hemagglutination (PHA) test with the use of associated diagnosticum showed that antibody titers in the sera of immunized rabbits increased 10- to 10(4)-fold in comparison with the titers observed prior to immunization. The PHA test with the use of the antigens contained in the vaccine revealed the accumulation of antibodies to each of the 4 components of the preparation in the blood sera of immunized rabbits.

[Initial experience with prophylactic Proteus vaccine immunization in an emergency clinic].

As early as the first 24 hours since a severe isolated locomotor trauma the patients were immunized with Proteus vaccine. Such vaccination is shown to stimulate the production of serum specific antibodies, to reduce contamination of the wound with gram-negative agents, to shorten hospital stay and healing of the wound versus subjects vaccinated with staphylococcal anatoxin and nonimmunized patients.

[The reactogenicity and immunological efficacy of a Klebsiella vaccine in donors].

Klebsiella vaccine, when injected subcutaneously to donors, proved to be faintly reactogenic and safe. The injection of the vaccine had no effect on changes in the morphological composition of peripheral blood and on liver function. In persons with the initially low content of IgG an increase in this characteristic was observed after immunization.
