Vibrio alginolyticus is a Gram-negative marine bacterium.[1][2] It is medically important since it causes otitis and wound infection.[1] It is also present in the bodies of animals such as pufferfish, where it is responsible for the production of the potent neurotoxin, tetrodotoxin.[3]
Vibrio alginolyticus are commonly found in aquatic environments. Some strains of V. alginolyticus are highly salt tolerant and commonly found in marine environment. S.I. Paul et al. (2021)[2] isolated and identified many strains of Vibrio alginolyticus from nine marine sponges of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh.
V. alginolyticus was first identified as a pathogen of humans in 1973. It occasionally causes eye, ear, and wound infections. It is a highly salt-tolerant species and can grow in salt concentrations of 10%. Most clinical isolates come from superinfected wounds that become contaminated at the beach. Tetracycline is typically an effective treatment. V. alginolyticus is rare cause of bacteremia in immunocompromised hosts.[4]
