(ORDO NEWS) — Ruminococcus bacteria, which inhabit certain areas of the human intestine, bring their owner not only benefit, but also harm. This was proven by American biologists who closely studied the intestinal microbiome.
It turned out that in the process of life, bacteria produce a certain metabolite. Which, at an increased concentration, begins to act on the nervous system.
Moreover, he does this by changing the corresponding genes, activating the process of self-destruction of nerve cells.
Studies on laboratory animals were used to confirm the results. They also showed this dependence. The mice were injected with the drug, after a while their mental abilities deteriorated, they found their way out of the maze more slowly and forgot how to do certain actions.
The intestinal microflora changes with age, the number of ruminocooks increases, while the number of bacteriophages that affect the entire microbiome decreases.
Thus, more and more specific metabolites constantly enter the body, which leads to a deterioration in cognitive abilities.
Moreover, experts also observed the opposite effect: when blocking the product of bacterial activity, the experimental animals improved coordination of movements and intelligence.
