Gram-negative, slightly curved rods, 0.3-0.5 x 0.9-2.0 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. Grows on blood agar at room
temperature
(18-22 ºC), 30 ºC and 37 ºC but not at 42 ºC under both aerobic and microaerobic
conditions, however, growth is weak under anaerobic conditions at 30 ºC. No
haemolysis on TSA + 5% sheep blood. Under aerobic conditions at 30 ºC grows on
Marine agar and on nutrient medium (0.5%, w/v NaCl) supplemented with 5%
sheep blood and also on this medium containing 2% or 4% (w/v) NaCl. No growth
occurs on minimal medium, Campylobacter Charcoal Deoxycholate Agar (CCDA),
MacConkey agar or on nutrient media supplemented with 5% sheep blood containing
1% glycine; 0.1% sodium deoxycholate; 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.
