Vibrio parahaemolyticus is a self-limiting, enterotoxic bacterium, typically causing acute gastroenteritis in humans. More severe cases of infection can occur in immune-compromised individuals, which can lead to septicemia and death, although this is very rare. Moderate to severe skin infections can also result from open wound exposure to V. parahaemolyticus in warm seawater, although this occurs less frequently than illness following ingestion of the organism[1]. V. parahaemolyticus is a Gram-negative curved rod, facultatively aerobic, non-spore forming, oxidase positive bacterium. It also has one polar flagellum contributing to its motility.
zooplankton when the temperature of the water increases up to 14 - 19 °C. V. parahaemolyticus is characterized
by its rapid growth under favourable conditions.
