Historical synonym:
Actinobaculum massiliae Greub and Raoult 2002.
Gram-positive straight to slightly curved rods, some of which exhibit branching.
Non-motile. Non-acid-fast. Non-spore-forming.

incubation at 37 ºC in a 5% CO
2 atmosphere. Non-haemolytic. CAMP reaction is
negative. Facultative anaerobic.
Isolated from urine.
