[edit] Description

Gram-positive, nonmotile and acid-fast rods (2-6 µm x 0.5 µm).

Colony characteristics

• White smooth and non-photochromogenic colonies.

Physiology

• Fast growth at 28°C and 37°C within 3 days, no growth at 42°C.
• Resistant to isoniazid, rifampin, Susceptible to ethambutol.

Differential characteristics Belongs to the Mycobacterium parafortuitum complex. Which unifies rapidly growing, scotochromogenic mycobacteria (M. parafortuitum, Mycobacterium aurum, Mycobacterium neoaurum, M. diernhoferi and Mycobacterium austroafricanum).

[edit] Pathogenesis

• Not associated with disease. Biosafety level 1.

[edit] Type Strain
