Gram-negative, straight rods, motile by one or more sheathed flagella. No lateral
flagella on solid media, not swarming on complex media.

Facultatively anaerobic. Can grow in nutrient broth with: 1-3.5% NaCl. No growth in
0% NaCl, 6% NaCl, 8% NaCl, 10% NaCl & 12% NaCl. Growth temperature 4-15 ºC,
no growth at 25-40 ºC. Media: nutrient agar + 5% human blood, tryptone soy broth
supplemented with NaCl to a final concentration of 1.5%.

Isolated from diseased salmonid fish raised in ponds in Norway. Susceptible to vibriostatic compound O/129. Resistant to
Carbenicillin (100 µg) and Ampicillin (10 µg).
Carbenicillin (100 µg) and Ampicillin (10 µg).
Causes Hitra disease (“hemorrhagic syndrome”) in salmonid fish. Pathogenicity may be lost by passage on artificial substrates but
can be regained by passage through fish.
Intraperitoneal injection of broth cultures of V. salmonicida into both rainbow trout and Atlantic salmon and challenge through water
reproduce symptoms identical to those of natural outbreaks.
