Description

Gram-positive, nonmotile and acid-fast rods or coccobacilli (0.4-0.5 μm x 0.6-1.4 μm).

Colony characteristics Smooth and scotochromogenic colonies of saffron yellow color.

Physiology

• Growth on Middlebrook 7H10 agar at 10-37 °C, optimum at 30 °C within 5 days.
• Susceptible to amikacin, azithromycin, ciprofloxacin, clarithromycin and ethambutol.
• Resistant to isoniazid.

Differential characteristics

• Mycobacterium murale and Mycobacterium tokaiense share an identical 5'-16S rDNA sequence
• However the ITS sequence of both species differs.

Pathogenesis

• Not known.

Type strain

• First isolated from water-damaged indoor building material, Finland.
