To effectively colonize a host animal and cause disease, many bacterial pathogens have evolved the mechanisms needed to invade and persist within host cells and tissues. Recently it was discovered that uropathogenic Escherichia coli , the primary causative agent of urinary tract infections, can invade and replicate within uroepithelial cells. This can provide E. coli with a survival advantage, allowing the microbes to better resist detection and clearance by both innate and adaptive immune defence mechanisms. Adhesive organelles, including type 1, P, and S pili along with Dr adhesins, promote both bacterial attachment to and invasion of host tissues within the urinary tract. Interactions mediated by these adhesins can also stimulate a number of host responses that can directly influence the outcome of a urinary tract infection.
