Mycobacterium flavescens 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.
Its name is derived from the Latin word "flavescens", which means "becoming golden yellow."
Description
Gram-positive, nonmotile and acid-fast rods.
Colony characteristics
- Rough, yellow-orange scotochromogenic, butyrous colonies.
Physiology
- Slow growth on Löwenstein-Jensen medium at 25-37 °C, but not at 45 °C within 7–10 days.
- Although growth rate is intermediate, metabolic and physiologic properties are more like rapidly growing species.
Differential characteristics
- Serologic specificity demonstrated by immunodiffusion.
- Related to Mycobacterium fortuitum: can be distinguished by its intense pigment production, and its slow rate of growth.
Pathogenesis
Not associated with disease. Biosafety level 2.
