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.
Pathogenesis
Type strain
- First isolated from human sputum in Madrid
Strain 938 = ATCC 700351 = CCUG 37984 = CIP 104973 = DSM 44476 = JCM 12375.
