Intestinal microbiocinosis status as a criterion for nutritional quality assessment

As a result of dynamic triple bacteriological examination for intestinal dysbiosis performed in 30 generally healthy 1st-year students who came to study from other regions, it was found that changes in the regime and quality of food led to the development of intestinal dysbiosis in 61.54% (out of 28 examined individuals) of nonresident first-year university students six months after the start of the study. The dysbiotic disorders of the intestinal microbiota were found to be primarily associated with a decrease (by 1-3 orders of magnitude) in the titer of obligate bacteria (bifido- and lactic bacteria, typical Escherichia coli). Against this background, the number of opportunistic transient microorganisms elevated. By the end of the follow-up period (after 9 months), the severity of dysbiotic changes enhanced in the majority of the examined students. The results of the performed studies indicate that the intestinal microbiota status in generally healthy individuals can serve as an objective and informative criterion for good nutrition.
