title: MRSA peritonitis secondary to perforation of sigmoid diverticulitis.
abstract: The occurrence of methicillin-resistant Staphylococcus aureus (MRSA) is well documented, but the pathology is usually associated with post surgical infections or long-term peritoneal dialysis. We report the case of a 50-year-old Caucasian man who presented with a one week history of left lower quadrant abdominal pain, poor appetite and nausea due to MRSA peritonitis secondary to perforated sigmoid diverticulitis. Despite a thorough search of the medical literature, we could not find that this problem has been previously described. We report this case to demonstrate the robust nature of MRSA, which has generally not been considered to be a normal colonizing bacterium of the sigmoid colon.
