Vibrio vulnificus diarrhea in a child with respiratory infection

Vibrio vulnificus is a rare cause of disease and it is often unrecognized and underreported. It is a lactose-fermenting, halophilic vibrio causing severe disease in immunocompromised patients, but causing a mild type of gastroenteritis in healthy people, usually associated with consumption of seafood. We report here a case of diarrhea due to V. vulnificus in a male child who was admitted for fever, loose motions and productive cough. There was no history of consumption of any seafood; so, the source of infection could not be traced. As V. vulnificus is a rare entity, clinicians should have a high index of suspicion for the bacteria, when patients present with gastrointestinal illness, fever or shock, with or without ingestion of raw seafood. Pediatricians should also be alert as the bacterium causes a potentially fatal disease in children.
