Bacteroides fragilis and intestinal epithelial cells shown as an overview tomogram with the modeled bacterium indicated with a black box (left, fig. A). The model reveals secretion of outer membrane vesicles (right, fig. B), bacterial structures discovered to interact with the immune system via genetic pathways linked to Crohn's disease. Green, outer membrane; light blue, inner membrane; pink, ribosomes; gold; outer membrane vesicles.
