[An analysis of the strain homogeneity of parietal biotopes of the gastrointestinal tract].
The lumen and parietal biotopes of the human gastrointestinal tract were investigated, i.e. the antibiotic sensitivity of strains E. coli and Enterococcus faecalis residing in them were comparatively analyzed. Certain isolation degrees not only of the parietal and fecal biotopes but also of certain micro-regions in the intestine wall were detected. The obtained data confirm a previously made assumption on the cluster distribution of microorganisms in the parietal mucin. The distinct strain differences between the parietal and fecal biotopes are not enough to completely extrapolate the available characteristics of the lumen microflora on the parietal microbiocenose. The above stated underlines the necessity in purpose-oriented research of parietal microbe populations of "internal" biotopes.
