title: [Analysis of ordinary microbial relationships in human colonic dysbacteriosis].
abstract: A relationship between the qualitative and quantitative characteristics of representatives of the normal microflora in biocenosis of the colonic lumen (CL) was studied in 18 patients with subacute bacterial endocarditis, 18 patients with rheumatic heart disease, 13 with chronic renal failure and 50 healthy individuals without clinical signs of dysbacteriosis. The number of intermicrobial relationships was found to be rather small both in health and in disease. However, a disease shows a considerably greater number of different relations, synergic ones in particular. Analysis indicated that in the conditions under study 72 to 93% of relations that were realized in the healthy human CL biotope disappeared and the established intermicrobial relationships were found 86-97% quite new. Summing up, the authors have concluded that, first, the CL microflora exists under the conditions of excess nutrient substrate and is not a factor of self-regulation, second, changes in the body's metabolic systems are primary in the diseases examined, which the normal lumenal microflora is responsive to.
