DIAGNOSTIC CRITERIA FOR INTESTINAL MICROBIAL LANDSCAPE IN CHILDREN WITH DYSPEPTIC DISORDERS

Abstract

The total biomass of microbial cells in the gastrointestinal tract (GIT) of an adult is on average 3-4 kg. About 450 species of microorganisms live in the gastrointestinal tract, and the total number of cells reaches 10¹⁴, exceeding the number of cells in a macroorganism. Intestinal microflora is divided into protective, saprophytic, and conditionally pathogenic. The protective microflora, which forms the basis of intestinal microflora, is represented by anaerobes - bifidobacteria (10⁸-10¹⁰) and lactobacteria (10⁶-10⁸), which form a protective film on the surface of the mucous membrane, and by aerobes - E. coli, which has normal enzymatic properties (10⁷-10⁸).
