Acid–alcohol-fast rods or coccoid cells (0.6-1.4 x 0.4-0.5 μm). Non-spore forming.
Non-motile. No branching.
Non-motile. No branching.
Growth occurs as smooth, saffron yellow, scotochromogenic colonies within 5 days
on tryptone soya blood agar. The temperature range for growth is 10-37 ºC, with
optimal growth at 30 ºC; does not grow at 42 or 45 ºC. Does not grow on MacConkey
agar (without crystal violet) or on 5% (w/v) NaCl agar.
