''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== 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mycobacterium canariasense」の詳細全文を読む スポンサード リンク
