Description
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
*The 16S rRNA and hsp65 gene sequences of ''M. canariasense'' are unique.
*Most closely related to ''
Mycobacterium diernhoferi'' and ''
Mycobacterium mucogenicum''.
Pathogenesis
*First isolated from blood samples obtained from 17 patients with
