obuense, first described as a scotochromogenic
RGM species isolated primarily from soil >40 years ago in Obu, Japan, is a catalase-positive, peroxidase-negative bacillus that can degrade salicylates, forming a black product (4,5).
Randall, "A mutant of a scotochromogenic
Mycobacterium detected by colony morphology and lipid studies," Journal of Bacteriology, vol.
Its colonies were originally described as smooth, scotochromogenic
, and 1-2 mm in diameter .
Four months after the specimen was collected, the organism in the PD fluid was identified at an outside laboratory as a scotochromogenic
Mycobacterium with susceptibilities to all antibacterial agents tested.
nov., a new slow-growing scotochromogenic
yongonense noted that it has a distinct rpoB sequence (1), identical to that of a distantly related scotochromogenic
, rapidly growing strain was isolated in 2012 from respiratory specimens of an HIV-positive 44-year-old Iranian man with chronic pulmonary disease.
To the Editor: Mycobacterium shigaense is a novel, slow-growing, scotochromogenic
mycobacterium (1), initially reported in 2012 as an opportunistic pathogen isolated from skin biopsy samples from a patient with a history of Hodgkin disease and severe cellular immunodeficiency.
nov., a pathogenic, slowly growing, scotochromogenic
avium DNA was negative), and routine cultures for mycobacteria yielded unidentified scotochromogenic
A new species of rapidly growing scotochromogenic
mycobacteria, Mycobacterium neoaurum.
Data from an extended panel of biochemical and cultural tests for conventional identification have not been reported; however, the appearance of a scotochromogenic
pale yellow pigment with growth at 45[degrees]C and a negative 3-day arylsulfatase test are in full agreement with our present and previous findings (7).
