Mycolicibacter arupensis (formerly Mycobacterium arupense) is a slowly growing mycobacterium first isolated from soil and human sputum samples in Spain.[1] Etymology: arupense, pertaining to the ARUP Institute for Clinical and Experimental Pathology, where the type strain was characterized.


Acid-fast staining Mycobacterium arupense .


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

Colony characteristics

  • Colonies are eugonic, rough and nonpigmented.



There are emerging reports of human pathogenesis caused by M. arupensis. Pulmonary infection and tenosynovitis have been documented.[citation needed] A recent case of recurrent soft tissue abscess caused by M. arupensis has been identified.[citation needed]
