On this page Vibrio are a species of bacteria that cause watery diarrhea and abdominal cramps. They are commonly found in coastal marine waters and, therefore, in filter-feeding shellfish such as oysters (which, for this reason, are best eaten fully cooked).

Infection with Vibrio species is especially dangerous when someone has a compromised immune system or liver disease. Vibrio can also cause severe wound infections. Non-cholera vibrio species include V. parahaemolyticus, V. vulnificus, and others. Also see: Cholera.
