Gram-negative, slightly curved rods, 0.3-0.9 x 1-1.8 μm. Motile by a single polar flagellum. Non-encapsulated. Non-spore-forming.
Colonies on Blood Agar incubated in aerobic conditions at 30 ºC for 48 h are 2-4 mm
in diameter, beige to off-white, circular with entire margins, convex, and
non-swarming. Pigments are not produced. All the strains grow on blood agar at
room temperature (18-22 ºC), at 30 ºC and 37 ºC under both aerobic and
microaerobic conditions with no significant differences. Growth is weak in anaerobic
conditions at 30 ºC and in aerobic conditions at 42 ºC. Haemolysis is not produced on
TSA medium supplemented with 5% sheep blood. Under aerobic conditions all the
strains grow on minimal medium, CCDA, Marine Agar and media containing 2% (w/v)
NaCl or 0.1% sodium deoxycholate. No growth occurs on media containing 4% (w/v)
NaCl; 1% glycine; 1% oxgall, 0.01%, 0.04% or 0.1% TTC, 0.001% brilliant green,
0.05% safranin, 0.0005% crystal violet; 0.005% basic fuchsin and medium with
64 mg / l cefoperazone. Variable grow on MacConkey agar.

Positive results for catalase, nitrate reduction, indoxyl acetate hydrolysis and oxidase.
Negative results for casein hydrolysis, lecithinase, starch hydrolysis, H2S production on TSI and Voges-Proskauer test.
Variable for alkaline phosphatase, hippurate hydrolysis and urease activity.
