[Fecal contamination with nuclease-positive bacteria as one of the indices of intestinal dysbacteriosis].

A comparative study of the levels of fecal contamination with opportunistic anaerobic nuclease-positive microorganisms was carried out in 114 normal subjects with normal intestinal microflora and in 82 somatic patients with disordered microflora in order to find new integral indicators of disturbed microflora of the intestine; along with routine methods, new techniques were employed. Integral assessment of the intestinal microflora was carried out by scintillation of the total count of facultative anaerobic microorganisms and the share of nuclease-positive bacteria, that yielded nucleic acid depolymerization areas 2 mm or higher from the border of the colonies.
