Description

Vibrio parahaemolyticus< /i> typically causes 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< /i> in warm seawater, although this occurs less frequently than illness following ingestion of the organism.V. parahaemolyticus< /i> is a Gram-negative curved rod, facultatively aerobic, non-spore forming, oxidase positive bacterium. It also has one polar flagellum contributing to its motility.
V. parahaemolyticus is a halophilic organism that thrives in coastal, brackish waters of marine and estuarine environments around the world including the United States, South America, Asia, Australia, and Europe. First cases of V. parahaemolyticus associated gastroenteritis were reported in Japan during the 1950s after mass consumption of raw and undercooked shellfish

Pathogenesis

Transmission

Vibrio parahaemolyticus is typically transmitted to human hosts through the consumption of raw and undercooked shellfish including clams, muscles, and oysters. Reports of contaminated crab and finfish have also contributed to incidences of infection in the past (Joseph)[1]. Annual increases in incidences worldwide are observed during the spring and summer months when water temperature is elevated and more favorable for the pathogen’s survival in its estuarine environments (CDC) [1] .

Infectious dose and incubation period

In an experimental study, the World Health Organization estimated the infectious dose to be 1,000,000 microorganisms. Clinical symptoms of the infection will manifest within 2-48 hours of ingestion, and will last anywhere from 2-8 days [1]
