[Morphological changes during intestinal dysbacteriosis in rats]

Inclusion into the food of rats of living E. coli strains produced an inflammatory-destructive process in the mucose of the cecum. When a strain isolated from the patient suffering from carcinoma of the stomach was fed the changes appeared in 2 to 3 months after the beginning of the experiment and were accompanied by atrophy of the mucosa; after colibacterin administration the inflammatory process occurred later, it was less pronounced and accompanied by the repair reaction.
