Gram-negative coccobacilli. Non-motile. Non-spore-forming.
Colonies are non-haemolytic on bovine agar, and the size varies from pin point to
1.5mm in diameter.No pigment production. No growth on KCN. V- and X-factors are
not required for growth. No growth on MacConkey agar.

Isolated from lesions in pigeon hawks (Accipiter gentiles).
The type strain was isolated from pneumonia in a pigeon hawk.
