[The intestinal microflora and acid-forming function of the stomach in peptic ulcer patients with Helicobacter pylori bacteriosis]. / Mikroflora kishechnika i kislotoobrazuiushchaia funktsiia zheludka u bol'nykh iazvennoi bolezn'iu s piloricheskim khelikobakteriozom.

Seventeen duodenal ulcer patients were examined. H. pylori were detected in all the patients by histological and bacteriological methods. Changes in the enteric microflora, manifested by a decrease in the number of lacto- and bifidobacteria and by an increased level of opportunistic microflora, were established. Cimetidine treatment and the suppression of the acid-producing function of the stomach augmented enteric dysbacteriosis and H. pylori contamination of the gastric and duodenal mucosa.

[The experimental and clinical effect of ciprofloxacin on the microflora of the gastrointestinal tract]. / Vliianie tsiprofloksatsina na mikrofloru zheludochno-kishechnogo trakta v éksperimente i klinike.

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]. / Sviaz' auksotrofnosti Salmonella typhi i Salmonella gallinareum so sposobnost'iu rasti na srede Simmonsa.

A total of 9 S. typhi strains and 1 S. gallinarum strain isolated from clinical material are auxotrophic with respect to tryptophan. The growth of S. typhi is accelerated in a glucose- and tryptophan-containing minimal medium with cysteine and methionine added. S. typhi strains are incapable of using sodium citrate as the only source of carbon. S. typhi cannot grow on Simmons citrate agar as these organisms are auxotrophic with respect to tryptophan and incapable of using sodium citrate as the only source of carbon, and S. gallinarum cannot grow on this medium as they are auxotrophic with respect to tryptophan.

[Identification of nonspecifically agglutinating strains of enterobacteria]. / Identifikatsiia nespetsificheski aggliutiniruiushchikhsia shtammov énterobakterii.

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.
