The article presents the results of a pilot study of the diversity and metabolic potential of the gut microbiome in adolescents with various forms of functional bowel disorder. The participants were the patients of the Clinic of Research Center for Family Health and Human Reproduction Problems. Biological material was studied using metagenomic sequencing of V3-V4 variable regions of the 16S rRNA gene. We showed that the composition of the minor component of the intestinal microbiome in adolescents with functional bowel disorder differs from that in the healthy subjects (control). Different types of transit disturbances in functional bowel disorder also differ from each other. According to the metabolic potential, adolescents can be divided into two groups irrespective of the pathophysiological manifestations: for one group, a more intensive metabolism in amino acid and lipid biosynthesis pathways was predicted than for the other.
Keywords: adolescents; functional bowel disorders; gut biocenosis; opportunistic microbiota.
