Description

Gram-positive, nonmotile, short to moderately long and acid-fast rods.
'Colony characteristics'

★ Eugonic, smooth, glistening and yellow-beige pigmented colonies. On Middlebrook 7H10 agar 0.5-2mm in diameter with entire margins.
'Physiology'

★ Growth on Löwenstein-Jensen media and Middlebrook 7H10 agar at temperatures between 22°C-37°C in less than 7 days.

★ Optimal growth at 31°C, no growth at 45°C.
'Differential characteristics'

★ Uniqueness of species supported by antigenic analysis (immunodiffusion) and specific lipid patterns.

★ A numerical taxonomy comparison showed close relationship to Mycobacterium aichiense.

Pathogenesis

★ Not known to be pathogenic in animals or humans.

★ Biosafety level 1
