Vibrio parahaemolyticus

Description and significance

Vibrio parahaemolyticus is a gram negative bacterium that is typically found in warm estuarine seawaters due to its halophilic (salt-requiring) characteristics. It is the number one leading cause of sea-food associated bacterial gastroenteritis in the United States.

V. parahaemolyticus causes diarrhea upon ingestion. While the overwhelming majority of people acquire the infection by eating raw or undercooked seafood (particularly shellfish and oysters), an open wound exposed to warm seawater can facilitate V. parahaemolyticus infection.

Isolation of V. parahaemolyticus is possible from cultures of stool, wound, or blood. Isolation from stool preferably involves a medium that contains thiosulfate, citrate, bile salts, and sucrose (TCBS agar).

Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?

Cell structure and metabolism

Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.

Human ingestion of V. parahaemolyticus causes various symptoms, including diarrhea, abdominal cramps, nausea, vomiting, headache, fever, and chills.

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?
