Catheter-associated symptomatic urinary tract infection is usually caused by organisms that originate from the patient's own colonic and perineal flora, or the hands of healthcare personnel during catheter insertion and manipulation of the collection system. Microbial species predominantly migrate into the bladder extraluminally via the mucoid film that forms between the catheter surface and the urethra. Current approaches for preventing catheter-related infections include antimicrobial modification of the catheter surface. Although these antimicrobial-based catheters aim to eradicate bacteria residing in the vicinity of the catheter surface, they can result in antibiotic resistance, which could have serious implications on patient care.
