[edit] Description

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

Colony characteristics

• Smooth, mucoid and nonphotochromogenic colonies.

Physiology

• Rapid growth on Löwenstein-Jensen medium at 22°C, 30°C, 37°C and 45°C within 2-4 days.
• Optimum growth at 30°C and 37°C.
• Resistant to isoniazid, cycloserine, capreomycin, pyrazinamide, and thiosemicarbazone
• Most strains are also resistant to ethambutol.

Differential characteristics

• Characterised by unique hsp65 gene, 16S rDNA and sodA sequences. *Closely related to M. fortuitum and M. peregrinum at the DNA homology level.
• Differentiation from M. fortuitum by its growth at 45°C and by its use of mannitol as a sole carbon source.

[edit] Pathogenesis

• Biosafety level 1

[edit] Type Strain

• First isolated from human sputum in Madrid

Strain 938 = ATCC 700351 = CCUG 37984 = CIP 104973 = DSM 44476 = JCM 12375.
