Gram-positive rods of various shapes, forming a branched structure with a ‘Y’ shape
at both sides. Non-motile. Non-spore-forming.
at both sides. Non-motile. Non-spore-forming.
Colonies are white, smooth, opaque, 1.0-2.0 mm in diameter after 3 days of
anaerobic incubation on TPY agar. Non-haemolytic. Can grow at 25-46 ºC, not at 20
ºC; optimally at 37 ºC. Grows at pH 5.5- 7.0, optimally at pH 6.5. Can grow under
aerophilic and microaerophilic conditions.
