Clinical and bacteriological studies have revealed that the production of colicin by Escherichia coli forming a part of intestinal microbiocenosis is related to the clinical manifestations of inflammatory diseases of the gastrointestinal tract. During the exacerbation of chronic inflammatory processes of the digestive system the proportion of colicin producing E. coli increases (more than 45%) in comparison with that of E. coli fecal strains isolated in children and adolescents regarded as healthy (less than 15%). The possibility of using the colicin producing activity of intestinal microflora for the evaluation of the dysbiotic states of gastrointestinal tract is discussed.
