The image shows the mucus layer (blue band) that protects the intestinal wall (pink) against bacteria and other things (dark blue at the top of the picture). The blue cells in the intestinal wall are mucus-producing goblet cells.

    Antibiotic usage can damage the protective mucus layer in the gut

    Researchers at Umeå University and Tartu University have found that a history of repeated antibiotic use causes defects in the normally protective mucus barrier of the gut, due to antibiotic-driven alterations in the microbiota. In a further study in a different collaboration, the researchers found a bacteria-independent mechanism through which antibiotics can damage the mucus barrier directly.
