Mycobacterium aichiense is a yellow-orange scotochromogenic, rapidly growing mycobacterium first isolated from soil and human sputum in Japan. It has not been formally associated with disease in humans.
- Gram-positive, nonmotile and acid-fast rods less than 2 µm. Acid-fast in young cultures but may lose acid-fastness on prolonged culture.
- Yellow-orange scotochromogenic colonies.
- 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.
- Does not grow in the presence of hydroxylamine HCl (500 mg/l) and does not degrade PAS.
- Not associated with disease.
- First isolated in Japan from soil and human sputum.
