''Mycobacterium kubicae'' is a
Gram-positive, nonmotile and
acid-fast bacterial species. Cells are typically rod-shaped, with some
coccoid
Coccoid means shaped like or resembling a coccus, that is, spherical.The noun coccoid or coccoids may refer to:
* a level of organization, characterized by unicellular, non-flagellated, non-amoeboid organisms, with a definite shape, in general b ...

Middlebrook 7H11 agar) are generally smooth and domed, with a yellow

Löwenstein-Jensen media they appear film-like. This species is not known to be pathogenic to humans. The species is named after American mycobacteriologist George Kubica.

Physiology
''M. kubicae'' requires 21 days of incubation between 33 °C and 37 °C to reach mature growth. Isolates have been shown to be resistant to the antibiotics
amikacin and
rifampin and partially resistant to
ciprofloxacin,
cycloserine,
ethambutol,
isoniazid,
rifabutin and
streptomycin. Susceptibility to
clarithromycin,
clofazimine and
ethionamide has been detected for some strains.
Type strain
The type strain of ''M. kubicae'', ATCC 700732, was isolated from human
sputum
Sputum is mucus that is coughed up from the lower airways (the trachea and bronchi). In medicine, sputum samples are usually used for a naked eye examination, microbiological investigation of respiratory infections and cytological investigations ...
. The strain may also be identified as CDC 941078, CIP 106428, DSM 44627, or JCM 13573.
