Vibrio is a genus of Gram-negative bacteria. Typically found in salt water, several species of which can cause foodborne infection, usually associated with eating undercooked seafood.
Several species of Vibrio are pathogens. Most disease-causing strains are associated with gastroenteritis, but can also infect open wounds and cause sepsis. They can be carried by numerous marine animals, such as crabs or prawns, and have been known to cause fatal infections in humans during exposure.
Many Vibrio species are also zoonotic. They cause disease in fish and shellfish, and are common causes of mortality among domestic marine life.
