Mycobacterium canariasense is a rapidly growing, non-pigmented mycobacterium first isolated from blood samples obtained from 17 patients with febrile syndrome. Etymology: canariasense; referring to the Latin adjective of the Spanish islands where all strains were isolated.

Description[edit]

Microscopy

  • Weakly acid-fast rods.

Colony characteristics

  • Visible growth appears in 2–3 days as smooth, moist, shiny, non-pigmented colonies on Löwenstein-Jensen medium. Growth later develops a more yellowish, smooth, moist and shiny appearance.

Physiology

  • Growth occurs at 30 and 37C, but not at 22, 42 or 45C.
  • Grows on MacConkey agar without crystal violet, but does not grow in the presence

of 5% NaCl.

  • Positive for arylsulfatase activity (3 days) and Tween 80 hydrolysis.
  • Produces a low level of heatstable catalase and is negative for reduction of nitrates.

Differential characteristics

Pathogenesis[edit]

  • First isolated from blood samples obtained from 17 patients with febrile syndrome in the Canary Islands.

Type strain[edit]

  • Strain 502329T =CIP 107998T =CCUG 47953T
