Escherichia coli

E.coli is a rod-shaped bacterium that is commonly found in the lower intestine and is a part of the normal flora of the intestine. Most E. coli strains are harmless, but some serotypes can cause serious infections in humans including cholecystitis, cholangitis bacteremia and urinary tract infections. The vast majority of infections caused by MDR E.coli  are complicated UTI, catheter-associated bacteruria and complicated abdominal infections. HAP and VAP infections are not commonly caused by E.coli.
