Description
Description
Microscopy
- Gram-positive, nonmotile and acid-fast rods less than 2µm. Acid-fast in young cultures but may lose acid-fastness on prolonged culture.
Colony characteristics
- Yellow-orange scotochromogenic colonies.
Physiology
- Grows at 25-37°C, not at 45°C, in 3-4 days or less
- Acid phosphatase and arylsulfatase (3 days) is positive.
- Negative for nitrate reduction, isonicotinamidase, and citrate utilisation.
