[edit] Description

Strictly aerobic, nonmotile, non-spore forming, acid-fast, Gram-positive rods.

Colony characteristics

• The colonies are nonphotochromogenic and intermediate between smooth and rough.

Physiology

• Growth occurs between 2 and 4 days on 5% sheep blood agar, Middlebrook 7H10 agar, and LJ slants at between at 24 and 37 °C; no growth is observed at 42 and 45 °C.

Differential Characteristics

• Differentiated from Mycobacterium abscessus by hsp65 sequence (5bp difference)

[edit] Pathogenesis

[edit] Type Strain

• The type strain was isolated from the sputum of a patient with hemoptoic pneumonia.

Strain CCUG 48898 = CIP 108297.
