Contents

Name

Etymology: Phylogenetic position between (Latin: interjectum) rapidly and slowly growing mycobacteria.

Description

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).

Physiology

  • 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

  • Chronic lymphadenitis
  • Biosafety level 2

    • Type strain

  • First isolated from a lymph node of a child with chronic lymphadenitis in Germany.

    • Strain 4185/92 = ATCC 51457 = CCUG 37514 = DSM 44064
