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 °C, but
not at 30 °C. 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.
