[The intestinal microflora and acid-forming function of the stomach in peptic ulcer patients with Helicobacter pylori bacteriosis].

Seventeen duodenal ulcer patients were examined. H. pylori were detected in all the patients by histological and bacteriological methods.

[The experimental and clinical effect of ciprofloxacin on the microflora of the gastrointestinal tract].

The study of the influence of cyprofloxacin on the microflora of the gastrointestinal tract has been made under experimental and clinical conditions. As revealed in this study, cyprofloxacin produces a corrective effect on the intestinal microflora; the action of this preparation, in contrast to that of other antimicrobial preparations, is retained for a long time. In patients having duodenal ulcer with bacteriosis caused by Campylobacter pylori and with intestinal dysbacteriosis the combination of cyprofloxacin and cimetidine yields a higher therapeutic effect than the use of cimetidine alone.

[Relation of Salmonella typhi and Salmonella gallinarum auxotrophicity to the ability to grow on Simmons' medium].

A total of 9 S. typhi strains and 1 S. gallinarum strain isolated from clinical material are auxotrophic with respect to tryptophan.

[Identification of nonspecifically agglutinating strains of enterobacteria].

Eight nonspecific agglutinating enterobacterial strains have been classified with the definite taxon on the basis of the data obtained by the study of their biochemical and serological properties. The possibilities offered by the supplementary methods for the study of such strains in practical laboratories are discussed.
