Gram-negative, usually bipolar, nonmotile cocobacilli, occuring singly or in pairs.
Colonies on bovine-blood agar are non-haemolytic, greyish, non-transparent but
translucent at the periphery, smooth and shiny, with a butyrous, circular, raised with
entire margin and 1-2 mm in diameter after 24-48 h at 37 ºC. Facultative anaerobic or
microaerophilic. Pigment is not formed. No V-factor requirement. Growth on
MacConkey is variable.

Isolated from isolated from the intestinal tract of duck.
Negative in symbiotic growth.

Isolates were not associated with pathological lesions.
