Historical synonyms: FAFLP group A47 Thompson, Hoste, Vandemeulebroecke & Swings, 2001
Gram-negative, rod-shaped cells, motile with polar flagella.
Can grow in nutrient broth with1.5 - 8% NaCl. No growth in 0% or 10% NaCl. Growth
occur at 4-35 ºC. No growth at 40 ºC.
Colonies on Marine agar are translucent, non-swarming, smooth, non-pigmented.
Colonies on TCBS agar are yellow bright, translucent, round, 1.5-2.8 mm in diameter.
No luminescence produced. Not swarming.
Isolated from healthy shrimp larvae (Penaeus chinensis) in China, sea bass (Dicentrarchus labrax) in Spain and from Atlantic salmon
(Salmo salar) in Tasmania.
Resistant to vibriostatic agent O/129, Gentamicin, Kanamycin & Streptomycin.
The strain LMG 13245 is pathogenic for Atlantic salmon (Salmo salar).
