Mycobacterium massiliense
is a rapidly growing Mycobacteria species sharing an identical 16S rRNA sequence with Mycobacterium abscessus. Etymology: massiliense, pertaining to Massilia, the Latin name of Marseille, France where the organism was isolated.

Contents

Description

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

Colony characteristics

  • The colonies are nonphotochromogenic and intermediate between smooth and rough, although it is possible to identify isolates with rough phenotype;

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)

Pathogenesis

Type strain

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

Strain CCUG 48898 = CIP 108297.
