Species description is based on a single isolate.
Gram-positive coryneform rods. Non-motile. Non-spore-forming. Tuberculostearic
acid is present. Mycolic acids are produced.
Colonies are cream-yellow, convex, dry and approximately 0.2–2 mm in diameter after
48 h incubation at 37 ºC on sheep-blood agar in aerobic conditions. Tween 80
encourages the growth. Non-haemolytic. Facultatively anaerobic.
Isolated from sputum.
Isolated from the sputum of a patient with pneumonia.
