Mycobacterium interjectum is a species of the phylum Actinomycetota (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus Mycobacterium.


Mycobacterium interjectum is Gram-positive, nonmotile and acid-fast rods (0.6-1.0 µm x 0.7-2.0 µm). Filaments (up to 6.0 µm) possible.

Colony characteristics

Dysgonic, smooth and scotochromogenic colonies (1–2 mm in diameter).


Differential characteristics
