Mycobacterium gilvum is a species of the phylum actinobacteria (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.
- 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
Type strain
First isolated from sputum and pleura fluid (London). Strain ATCC 43909 = CCUG 37676 = CIP 106743 = DSM 44503 = JCM 6395 = NCTC 10742.
