Description is based on a single isolate.
Thin, pleomorphic coryneform cells. Non-motile. Non-spore-forming.
Colonies are dry, small (< 0.5 mm), slightly greyish after 2 days at 37 ºC on Columbia
blood agar supplemented with 5% sheep blood; the colonies are larger, slightly
creamy on BHI agar and TSA supplemented with 1% Tween 80. Nonhaemolytic.
Facultatively anaerobic.

Isolated from human.
Isolated from a patient with appendicitis accompanied by abscess formation.
