[Quantitative and species composition of conditionally-pathogenic microorganisms of the families Enterobacteriaceae and Pseudomonadaceae in healthy subjects and intestinal dysbacteriosis].
The spread and quantitative content of opportunistic microorganisms belonging to the families Enterobacteriaceae and Pseudomonadaceae in clinically healthy persons and in somatic patients with intestinal dysbacteriosis were studied. Opportunistic enterobacteria were shown to be widely spread in healthy persons (K. pneumoniae in 45%, Citrobacter in 44%, E. aerogenes in 17%, E. cloaceae in 11%). In clinically healthy persons most of these cultures (72.3%) were detected in an amount not exceeding 1 X 10(4) organisms per 1 g of feces, while in patients with intestinal dysbacteriosis opportunistic enterobacteria were detected in most cases (70.9%) in an amount of 1 X 10(5)--1 X 10(8) organisms per 1 g of feces. The results of this study suggest that the presence of the opportunistic enterobacteria K. pneumoniae, Citrobacter, E. aerogenes and E. cloaceae in an amount not exceeding 1 X 10(4) organisms per 1 g of feces is normal for healthy persons, while the increase of their presence in the intestine to 1 X 10(6)--1 X 10(8) is indicative of intestinal dysbacteriosis.
