Enteric bacteria are able to resist high concentrations of bile encountered throughout the gastrointestinal tract. Here we review the current mechanisms identified in the enteric bacteria Salmonella, Escherichia coli, Bacillus cereus, and Listeria monocytogenes to resist the dangerous effects of bile. We describe the role of membrane transport systems and their connection with DNA repair pathways to confer bile resistance to these enterics. We discuss the findings from recent investigations that indicate bile tolerance is dependent upon being able to resist the detergent properties of bile at both the membrane and DNA level.
