Mycobacterium gilvum 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. Etymology: gilvum, Latin for pale yellow. Description
Pleomorphic gram-positive, nonmotile and acid-fast rods. Colony characteristics
Pale yellow, Scotochromogenic, and smooth pleomorphic colonies. Physiology
Rapid growth on Löwenstein-Jensen medium at 25 °C and 37 °C, but not at 45 °C, within 7 days. Resistant to isoniazid, rifampicin, and sodium aminosalicylate. Differential characteristics
5 species-specific antigens, demonstrable in immunodiffusion tests. Pathogenesis
Not assumed to be pathogenic. Biosafety level 1
