Cholera is an acute diarrheal infection caused by ingestion of food or water contaminated with the toxin-producing strains of the bacterium Vibrio cholerae.
The bacteria Vibrio parahaemolyticus is from the same family as the species responsible for causing cholera. It causes gastrointestinal illness in humans and can be found naturally in the coastal sea waters of the United States and Canada. The bacteria is halophilic, meaning it requires salt to survive and can be found in higher concentrations in the warmer months of the year.
The bacteria Vibrio vulnificus is from the same family as Vibrio parahaemolyticus and the species responsible for causing cholera. Due to its affinity for salt (halophilic), it naturally resides in warm marine and estuarine waters.
Other Vibrio infections
Several other members of the Vibrio family are known for causing a range of infections. These bacteria also have an affinity for salt (halophilic) and can be found in warm marine, estuarine and brackish waters.
