Acid-fast, irregular rods, with frequent V forms during cell division. Gram-positive.
Does not form endospores or conidiospores.
Does not form endospores or conidiospores.
Colonies are non-pigmented and grow in 3-4 days at 22-30 ºC incubation
temperature. No growth at 37 ºC. Grows well on R2A medium, 5% sheep blood agar,
Middlebrook 7H10 agar and Lowenstein-Jensen slants. No growth on MacConkey
agar without crystal violet or in 5% w/v NaCl media. Aerobic.
