[edit] Description

Gram-positive, nonmotile, and partial acid-fast rods.

Colony characteristics

• Yellow, scotochromogenic, smooth and slimy (in dense growth) colonies (diameter 2-5mm). Distinct and drier colonies at temperatures between 40° and 65°C.

Physiology

• Aerobic and thermophilic rapid growth on Löwenstein-Jensen medium at a temperature range between 30°C and 65°C.
• Susceptible to streptomycin, ethambutol, cycloserine, ciprofloxacin and clarithromycin.
• Resistant to isoniazid, rifampin and prothionamide.

Differential characteristics

• Closely related to the slowly growing species M. xenopi.
• Easy to distinguish from other mycobacteria by its growth at 65°C
• Inability to utilise any sugar
• Ability to split benzamide.

[edit] Pathogenesis

• First isolated from urine in the German province of Hessen.
• Biosafety level 1

[edit] Type Strain

Strain 3849 = CCUG 37519 = CIP 105218 = DSM 44199 = JCM 12690.
