Urolithins, ellagitannin metabolites produced by colon microbiota, inhibit Quorum Sensing in Yersinia enterocolitica: Phenotypic response and associated molecular changes

► Urolithins inhibit QS associated processes in Yersinia enterocolitica. ► Urolithins reduce the levels of C6-HSL and 3-oxo-C6-HSL in Y. enterocolitica. ► Urolithins do not downregulate the expression of yenI or yenR. ► Exposure to urolithins is associated to an induction of motility genes. ► Urolithins may contribute to ameliorate the inflammatory response to enteropathogens.
