Macromorphology (smell):
Micromorphology: Motile and curved rod (0.5-0.8 x 1.4-2.6 µm) with one polar flagellum.
Gram +/Gram -:G-
Metabolism: Fakultatively anaerobic
Other Enzymes: Tryptophanase + (=indole +)
Biochemical Tests: Citrate +, Voges-Proskauer -
Fermentation of carbohydrates:
Glucose (gas) -
Spec. Char.: Halophilic. Can grow in up to 8% NaCl.
Hosts: Man, crustacean and fish
Reservoir: Tempererate seawater. Crustacean and fish.
Disease (Swedish):Har rapporterats orsaka "rödbenssjuka" hos tigerräkor. Gastrointestinal sjukdom (gastroenterit) hos människa (matförgiftning).
Disease (English):Has reported to cause red leg disease in black tiger shrimps. Human gastrointestinal illness (gastroenteritis).
Clinical Picture: Diarrhea, nausea, vomiting, abdominal pain, fever and headache
Virulence Factors: The genome carries a pathogenicity island (PAI) in the second chromosome. This PAI contains a type III secretion system (T3SS), which can inject virulence proteins into the host cells to disturb the host cell functions and may cause cell death by apoptosis.
