Dynamics of gut colonization by commensal and pathogenic bacteria that attach to the intestinal epithelium

Abstract excerpt

Bacterial adherence to the intestinal epithelium plays a role in niche establishment in the gut lumen. Through sampling natural populations of Caenorhabditis, we discovered several bacterial species that adhere to the intestinal epithelium via polar, intimate association, best described as attachment. These bacteria had varying effects on host fitness and physiology, with one species having negative effects, and...
