Vibrio kanaloae is a species of curved, motile, moderately halophilic and Gram-negative bacteria belonging to the family Vibrionaceae. It was originally isolated from Hawaiian and Mexican seawater as well as marine animals and was described as a new species in 2003. [1]

Etymology

The specific epithet ‘‘kanaloae’’ honours Kanaloa, the Hawaiian deity of the ocean, reflecting both the marine habitat of the bacterium and the site of its first isolation. [1]

Taxonomy and characteristics

The species is placed in the class Gammaproteobacteria and the order Vibrionales. Cells are oxidase-positive, facultatively anaerobic rods that grow best at 25–30 °C in 2–3 % NaCl and form smooth, cream-coloured colonies on marine agar. Polar flagella provide rapid swimming motility. [3]

Pathogenicity

Immersion-challenge experiments have shown that strain SbA1-1 can cause high mortality in the ark clam Scapharca broughtonii , producing typical vibriosis lesions in gill and hepatopancreas tissues at water temperatures ≤ 15 °C. [4] Comparative genomic analyses support its role as an opportunistic pathogen of bivalve larvae and juveniles. [3]
