This study shows antibiotics damage the colonic mucus barrier independently of microbiota, leading to bacterial penetration and IBD exacerbation.

This study shows that repeated antibiotic use in humans leads to microbiota changes that impair intestinal mucus function in mice.

This study shows that the gut bacterium Blautia helps maintain colonic mucus function under low fiber diets by producing short-chain fatty acids that activate Ffar2.
