[edit] Description

Microscopy

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

Colony characteristics

Rough, and nonphotochromogenic colonies.

Physiology

Rapid growth on egg media at 22-45°C, not at 52°C, in less than 5 days.
Niacin negative, catalase positive, β-galactosidase usually positive.
Tween 80 not hydrolysed after 14 days.
Resistant to 5% NaCl, p-nitrobenzoic acid (0.5mg/ml) and thiophene-2-carboxylic acid hydrazide (1mg/l).

[edit] Pathogenesis

Not associated with disease.
