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.

Etymology

[edit]

Its name is derived from the Latin word "flavescens", which means "becoming golden yellow."

Description

[edit]

Gram-positive, nonmotile and acid-fast rods.

Colony characteristics

[edit]

Physiology

[edit]
  • 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

[edit]

Pathogenesis

[edit]

Not associated with disease. Biosafety level 2.

Type strain

[edit]
  • Normal human flora, environmental habitat.
  • First isolated from a drug treated tuberculous guinea pig (Mexico).

Strain ATCC 14474 = CCUG 29041 = CIP 104533 = DSM 43991 = JCM 12274 = NCTC 10271 = NRRL B-4038.
