Gram-negative cells. Non-motile.
Colonies are circular, with an entire edge, buttery consistency, 1-2 mm in diameter and
non-haemolytic after 24 h of incubation at 37 ºC on bovine blood agar. Pigment is not
produced. Synthesize porphyrin without X factor requirement. Some isolates may
require NAD (V-factor) for growth. Can grow weakly with KCN. No growth on MacConkey
agar, except for the type strain.

Found in rats but can colonize other rodent species (mice, Syrian hamster, Guinea pig). The type strain was isolated from a chicken
in Denmark.
