• Yellow-orange, scotochromogenic colonies, but the pigmentation deepens with exposure to light. Older cultures are more dry and rough.

Physiology

• Rapid growth on Löwenstein-Jensen medium at 28°C and 37°C, but not at 45°C.

[edit] Pathogenesis

• Pathogenicity in humans is not known. Production of a local regressing infection but no death in mice.
• Biosafety level 1

[edit] Type Strain
