The results of a recent study on mice showed that probiotics are not always useful for the intestines. And this applies to at least one type of bacteria.
According to the results of a new work published in MBIO, a single dose of bacteria Lactobacillus acidophilus (often they are found in milk and yogurt) can facilitate the penetration of Clostridioides difficile into the intestines of mice that recently received a course of antibiotics. On the other hand, the Lactobacillus Gasseri LG-36 strain helped to resist the infection of C. Difficile. This pathogen can cause a heavy, and sometimes life -threatening diarrhea after taking antibiotics.

L. Gasseri LG-36 also contributed to the growth of bacteria of the Muribaculaceae family. These effects were preserved for a long time after L. Gasseri LG-36 fell into the intestines of mice.
At the same time, scientists note that the results obtained on rodents can be not applicable to a person. Types and strains indicated on the labels can behave differently depending on the state of human health, the composition of bacteria in probiotics, microbes that are in the body.
