[Gastrointestinal tract microflora in nonspecific ulcerative colitis].

The species and quantitative composition of the normal and conditionally pathogenic microflora of the stomach, the proximal portion of the small intestine, in material obtained by biopsy from the mucosa of this portion, and in feces was studied in 10 patients with non-specific ulcerative colitis. The study was made before and after treatment. Before treatment in most of the patients gastric juice and the proximal portion of the small intestine were found to be greatly contaminated with microflora commonly present in feces, and in fecal microflora sharp dysbiotic changes were observed.

[Method of determining the microbial flora of the small intestinal cavity and mucosa in different gastrointestinal tract diseases].

Intestinal microflora in patients with chronic enterocolitis and duodenal ulcer was studied. Both the cavity of the small intestine and the structures of its mucosa were investigated. The method of aspiration biopsy was used, the samples of multiple washings of the intestinal mucosa and its homogenate were used for seeding.
