Age features of species diversity lactobacill of large intestine in residents of Tyumen

Abstract

Aim. To study the species composition of bacteria of the genus Lactobacillus, inhabiting the distal large intestine of patients of different age groups, residents of the city of Tyumen.Materials and methods. The content of bacteria of the genus Lactobacillus in feces of 1545 residents of Tyumen aged 1 month to 76 years who complained of intestinal dysfunction was analyzed. Grown colonies of lactobacilli identified by mass spectrometry.Results. The study of the species composition of lactobacilli showed their wide diversity depending on age. Statistically significant differences in the content of lactobacilli in the large intestine in different age groups of patients were identified by the species L. rhamnosus and L. fermentum. Conclusion. Information on the species characterization of lactobacilli that inhabit the large intestine of patients, taking into account age-related features, will increase the effectiveness of the correction of the microbiota of the large intestine and the prevention of inflammatory diseases of the gastrointestinal tract.
