Vibrio parahaemolyticus
Vibrio parahaemolyticus
Vibrio parahaemolyticus (pronunciation: /vɪbri.oʊˌpærə.hiːməˈlɪtɪkəs/) is a gram-negative, halophilic bacterium that inhabits marine and estuarine environments.
Etymology
The name Vibrio parahaemolyticus is derived from the Latin words vibrio meaning "to vibrate", para meaning "beside" or "near", and haemolyticus referring to the bacterium's ability to lyse red blood cells.
Characteristics
Vibrio parahaemolyticus is a rod-shaped bacterium that is motile due to the presence of a single polar flagellum. It is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. The bacterium is also halophilic, requiring salt for growth, and is thermophilic, preferring warm temperatures.
Pathogenicity
Vibrio parahaemolyticus is a major cause of foodborne illness, particularly in regions where seafood is a dietary staple. The bacterium can cause gastroenteritis in humans when ingested, typically through the consumption of raw or undercooked seafood. Symptoms of infection include diarrhea, vomiting, abdominal cramps, and fever.
Prevention and Treatment
Prevention of Vibrio parahaemolyticus infection primarily involves proper food handling and preparation, particularly of seafood. Treatment typically involves rehydration and, in severe cases, antibiotics.
