[edit] Description

Microscopy

• Gram-positive, nonmotile, acid-fast, coccoid rods.

Colony characteristics

• Dysgonic and yellow photochromogenic (pigment not produced in the dark) colonies.

Physiology

• Slow growth on Löwenstein-Jensen medium at 37°C after 15-21 days.

Differential characteristics

• Unique 16S rRNA sequence.
• Biochemically M. asiaticum (photochromogenic) and Mycobacterium gordonae (scotochromogenic) can only by the mode of pigmentation.

[edit] Pathogenesis

• Rarely causes human pulmonary disease.

[edit] Type Strain

• First isolated from monkeys in 1965.
• Strain ATCC 25276 = CCUG 29115 = CIP 106809 = DSM 44297 = JCM 6409.
