Description

Microscopy

  • Gram-positive, nonmotile and acid-fast rods (1-3 µm x 0.5-0.7 µm), mostly strong acid-fast.

    • Colony characteristics

  • Colonies are eugonic, rough and nonpigmented.

    • Physiology

  • Colonies occur within 5 days at 30°C (optimum temperature, no growth at 45°C) on Löwenstein-Jensen medium and on Middlebrook 7H10 agar.
  • No growth on MacConkey agar without crystal violet.
  • The type strain is resistant to D-cycloserine, streptomycin, isoniazid (0.1 and 1 mg/l), rifampin, and thiacetazone and is susceptible to isoniazid (10 mg/l), kanamycin, and capreomycin.

    • Pathogenesis

    There are emerging reports of human pathogenesis caused by Mycobacterium arupense. Pulmonary infection and tenosynovitis have been documented. A recent case of recurrent soft tissue abscess caused by Mycobacterium arupense has been identified.

    Type strain

  • First isolated from water samples, from soil and human sputum samples, Spain.
  • Strain AR30097 = ATCC BAA-1242 = DSM 44942.
