Gram-negative, non-motile rods.
Colonies on on blood agar are non-haemolytic, circular and slightly raised with an
entire margin, smooth, shiny and opaque with a greyish tinge, 1.0–1.5 mm in
diameter after aerobic incubation at 37 °C for 24 hours. After incubation for 48 hours,
a diameter of 2.0 mm might be reached. The consistency is buttery and colonies do
not adhere to the agar
surface. No growth on MacConkey agar. No pigments produced.

Isolated from parrots, budgerigars, parakeets and a chicken.
May be involved in respiratory tract infections or septicaemia in birds.
