Gram-negative rods, 0.2-0.4 x 1-2 μm. Non-motile. Non-spore-forming. Capsulated.
Colonies on blood agar are convex, circular and greyish-white to yellowish colonies
with entire edge and smooth surface. In nutrient broth, produce moderate turbidity
and pellicle near the surface after 24-48 h incubation. Does not require special
growth factors. Grows on conventional media. No growth on MacConkey agar. Growth
temperature is 37 ºC. Can grow at 42 but not at 24 ºC. Microaerobic; grows aerobically
(although most strains less abundant), but not anaerobically.

Isolated mainly from pigeons samples of lungs, air sac exudate and trachea mucosa and less frequently from other organs such as
liver and spleen. They can also be isolated from swabs taken from the palatine cleft or trachea of living acutely diseased pigeons.

May be associated with respiratory disease in pigeons.
