[The screening diagnosis of intestinal dysbiosis].

A screening method for the evaluation of the state of intestinal microbiocenosis by monitoring the persistence sign of bacteria, their anti-interferon activity, was proposed. The examination of patients with dysbiosis of the intestine has shown that their intestinal microflora was found capable of inactivating the preparation of human leukocytic interferon at a definite concentration 8.7 times more often than the intestinal microflora of healthy persons. The number of interferon-active colonies correlated with the severity of changes in intestinal microbiocenosis and the degree of clinical manifestations of the disease.
