Historical synonym: Vibrio wodanis Lunder, Sorum, Holstad, Steigerwalt, Mowinckel
and Brenner 2004.
Gram-negative, short or elongated, non-spore-forming rods, motile by means of
multiple polar flagella.
Colonies are round, opaque, yellow (yellow-orange cell-associated pigment),
non-swarming and non-luminescent. Haemolytic when grown on bovine blood agar
containing 2% NaCl.The optimal NaCl concentration for growth is 1 to 4%. Growth
occurs at 4-25 ºC, but not at 30 ºC. Facultatively anaerobe.
Isolated from Atlantic salmon (Salmo salar). Susceptible to 2,4-diamino-6,7-diisopropylpteridine ( O/129 vibriostatic agent). Sensitive
to carbenicillin (100 µg) and novobiocin (5 µg).
Causes an ulcerative skin disease (“winter ulcer”) in Atlantic salmon.
