Gram-positive typically club-shaped rods. Non-motile. Non-spore-forming. Mycolic
acids are produced.
acids are produced.
Colonies on sheep blood agar are circular with entire edges and whitish. Optimum
growth temperature is 37 ºC. Non-haemolytic. CAMP-negative. Grows aerobically and
in the presence of a 5% CO2-enriched atmosphere.
