Mycobacterium mageritense
Mycobacterium mageritense
Etymology: Magerit, is Arabic for Madrid, where it was first isolated from human sputum. 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
Biosafety level 1
