Acid-alcohol-fast rods, frequently curved. Non-spore-forming. Filaments not produced.
Colonies are smooth / occasionally rough, and orange on Middlebrook 7H10 agar.
Cells on LJ medium grow in a film-like manner and produce an orange pigment.
Optimum growth at 37 ºC and no growth at 45 ºC. No growth is observed on
MacConkey agar or on culture medium containing 5% NaCl.

Species is indistinguishable from M. scrofulacem by morphobiochemical characters.
Positive results for heat stable catalase, tellurite reductase, pyrazinamidase and urease.
Negative results for arylsulfatase (3 and 14 days), niacin accumulation, nitrate reductase, and Tween 80 hydrolysis.
