Non-antibiotic associated C. difficile diarrhea in a 7 week-old infant.

We describe a rare case of non-antibiotic associated severe C. difficile diarrhea in a 7-week-old boy. He had massive fluid loss and electrolyte imbalance. He required total parentral nutrition for 10 days and eventually recovered with oral metronidazole. Most of the reported cases in literature are associated with prior antibiotic exposure or in hospitalized patients.
