- Repeated antibiotic use alters gut's composition of beneficial microbes, study shows
September 13, 2010
Repeated use of an antibiotic that is considered generally benign, because users seldom incur obvious side effects, induces cumulative and persistent changes in the composition of the beneficial microbial species inhabiting the human gut, researchers at the Stanford University School of Medicine have found.
