Acid-alcohol-fast short rods, with occasional coccoid forms. No cording, spores or
filaments are present.
filaments are present.
Colonies are small, scotochromogenic and bright yellow. On Middlebrook 7H10,
Ogawa and Stonebrink media, mature growth develops after 28 days incubation at 36
°C. Growth is slower at 25 and 30 °C. No growth at 42 °C. No growth on MacConkey
agar.
