Gram-positive coryneform rods. Non-motile. Non-spore-forming. Tuberculostearic
acid is not present. Mycolic acids are present.
Colonies are whitish, low-convex, smooth and approximately 1-2 mm in diameter
after 48 h incubation at 37 ºC on sheep-blood agar. CAMP-positive. Facultatively
anaerobic.
Isolated from the cloacae of apparently healthy wild magellanic penguins.
Undetermined.
