Gram-negative, curved cells, 2-3 x 1 µm, motile by at least one polar flagellum.
Colonies on TSA are translucent, non-swarming , rounded with entire margins.
Colonies are yellow, translucent, 5 mm in diameter on TCBS agar.
Facultatively anaerobic. Can grow in nutrient broth with: 2%, 4% & 6% (variable) NaCl.
No growth in 0% or 8% NaCl. Growth temparature 4 -20 ºC. No growth at 35 or 40 ºC.
