Description
Short gram-positiveGram-positive
Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. This is in contrast to Gram-negative bacteria, which cannot retain the crystal violet stain, instead taking up the counterstain and appearing red or pink...
, nonmotile and acid-fast
Acid-fast
Acid-fastness is a physical property of certain bacteria, specifically their resistance to decolorization by acids during staining procedures.Acid-fast organisms are difficult to characterize using standard microbiological techniques Acid-fastness is a physical property of certain bacteria,...

Colony characteristics
- Yellow-orange, scotochromogenicScotochromogenicScotochromogenic bacteria develop pigment in the dark or in the light. Runyon Group II nontuberculous mycobacteria are examples but the term could apply to many other organisms....
coloniesColony (biology)In biology, a colony reference to several individual organisms of the same species living closely together, usually for mutual benefit, such as stronger defense or the ability to attack bigger prey. Some insects live only in colonies...
, but the pigmentation deepens with exposure to light. Older cultures are more dry and rough.
Physiology
- Rapid growth on Löwenstein-Jensen medium at 28°C and 37°C, but not at 45°C.
Pathogenesis
- PathogenicityPathogenicityPathogenicity is the ability of a pathogen to produce an infectious disease in an organism.It is often used interchangeably with the term "virulence", although virulence is used more specifically to describe the relative degree of damage done by a pathogen, or the degree of pathogenicity caused by...
