Description
Microscopy
- Gram-positive, nonmotile and acid-fast rods (3-7 µm long). Frequently join to grow in long threads.

- Niacin negative, catalase positive, β-galactosidase usually positive.
- Tween 80 not hydrolysed after 14 days.
- Resistant to 5% NaCl, p-nitrobenzoic acid (0.5 mg/ml) and thiophene-2-carboxylic acid hydrazide (1 mg/l).
Pathogenesis
Not associated with disease.
Distribution
- Found in soil world-wide
Type strain
