Acid-fast rods. Gram-positive. Non-motile. Non-sporeforming. No branching.
Colonies are smooth and strongly yellow pigmented and grow on
Lowenstein-Jensen and Middlebrook 7H11 media after 2-3 weeks of incubation at 37
ºC. Grow slower at 30 ºC. No growth at 42 ºC. No growth on MacConkey agar without
crystal violet.
