Vibrio alginolyticus

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.[2] 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.[4] It occasionally causes eye, ear, and wound infections.[4] It is a highly salt-tolerant species and can grow in salt concentrations of 10%.[4] Most clinical isolates come from superinfected wounds that become contaminated at the beach.[4] Tetracycline is typically an effective treatment.[4] V. alginolyticus is rare cause of bacteremia in immunocompromised hosts.[4]
