The body’s natural response to an invader is to attack, which means that an indwelling urinary catheter is treated as a foreign body by the immune system. Within 6 hours of catheter placement, biofilm formation begins to adhere to the catheter providing a rich habitat for microorganisms to infect the host (Bjornson & Macera, 2009). Biofilm is responsible for approximately 65%-80% of infections and are up to 1000 times less receptive to antibiotics (Bjornson & Macera, 2009). The most frequent microbe to infect the host is the gram negative E. coli, as quickly as 1-3 days after catheter
