A flexible sigmoidoscopy was performed, revealing that ‘a segmental pseudomembrane was found from rectum to sigmoid colon’. Clostridium difficile PCR on the stool was repeated twice and resulted negative both times. A food history prior to onset of symptoms was consistent with Staphylococcal food poisoning and a stool culture was positive for heavy growth of methicillin-resistant Staphylococcus aureus and the absence of enteric flora. The patient was successfully treated with oral vancomycin. ER -
