Abstract
Mycobacterium duvalii is a species of the phylum Actinomycetota (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus Mycobacterium.
Description
Gram-positive, nonmotile and pleomorphic acid-fast rods. Colony characteristics
Bright yellow pigmented, scotochromogenic and rough or smooth colonies on Löwenstein–Jensen medium.
Physiology
Fast growth on Löwenstein–Jensen medium at 25 °C and 37 °C within 7 days. No growth at 45 °C. Resistant to isoniazid, rifampicin, and sodium aminosalicylate.
Differential characteristics
Characterised by the possession of 6 species-specific antigens demonstrable in immunodiffusion tests.
