Vibrio parahaemolyticus  Vibrio parahaemolyticus is a curved,
rod-shaped, Gram-negative bacterium found in brackish[1]
saltwater, which, when ingested, causes gastrointestinal illness
in humans.[1] V. parahaemolyticus is oxidase positive,
facultatively aerobic, and does not form spores. Like other
members of the genus Vibrio, this species is motile, with a
single, polar flagellum.[2]   While infection can occur by the
fecal-oral route, ingestion of bacteria in raw or undercooked
seafood, usually oysters, is the predominant cause the acute
gastroenteritis caused by V. parahaemolyticus.[3] Wound
infections also occur, but are less common than seafood-borne
disease. The disease mechanism of V. parahaemolyticus infections
has not been fully elucidated.[4]  Clinical isolates usually
possess a pathogenicity island (PAI) on the second chromosome.
The PAI can be acquired by horizontal gene transfer and contains
genes for several virulence factors. Two fully sequenced
variants exist of the V. parahaemolyticus PAI with
