Severe MRSA Enterocolitis Caused by a Strain Harboring Enterotoxins D, G, and I

Abstract

We describe a case of methicillin-resistant Staphylococcus aureus (MRSA) enterocolitis in a healthy adult with previous antibiotic exposure. Colonoscopy revealed diffuse colitis and mild ileitis without ulceration. Stool cultures demonstrated abundant growth of MRSA and absent normal flora. Oral vancomycin treatment was effective and seems to be the consensus choice for therapy.
