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.
Name
[edit]Etymology: Phylogenetic position between (Latin: interjectum) rapidly and slowly growing mycobacteria.
Description
[edit]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
[edit]Dysgonic, smooth and scotochromogenic colonies (1–2 mm in diameter).
Physiology
[edit]- Slow growth on Löwenstein-Jensen medium at temperatures between 31°C and 37 °C within 3–4 weeks.
- Susceptible to rifampicin.
- Resistant to isoniazid and ethambutol.
Differential characteristics
- Most closely related to M. simiae.
- Phylogenetic position between rapidly and slowly growing mycobacteria.
Pathogenesis
[edit]- Chronic lymphadenitis
- Biosafety level 2
Type strain
[edit]- First isolated from a lymph node of a child with chronic lymphadenitis in Germany.
Strain 4185/92 = ATCC 51457 = CCUG 37514 = DSM 44064
