title: [Biological properties of opportunistic enterobacteria isolated from healthy persons and from patients with intestinal dysbacteriosis].
abstract: The comparative study of the signs of pathogenicity in 724 enterobacterial strains and in some species of nonfermenting microorganisms isolated from the feces of 115 somatic patients with intestinal dysbacteriosis and 80 healthy persons (565 strains) has revealed that microorganisms belonging to the same species may essentially differ in their occurrence, in the activity of the enzymes (DNAase, RNAase, phosphatase) which they release into the culture medium, as well as in their capacity to give the positive reaction with Congo red. At the same time, the cultures isolated in cases of intestinal dysbacteriosis have been found to be biologically more active.
