The cell size of Mycobacterium smegmatis ranges from 3-5 micrometers.
No, Mycobacterium smegmatis does not form endospores. Endospores are typically formed by some bacterial species in response to harsh environmental conditions as a survival mechanism, but Mycobacterium species, including M. smegmatis, do not produce endospores.
Mycobacterium smegmatis is not a major human pathogen and is considered non-pathogenic to humans. It is commonly used as a model organism in research due to its genetic similarity to other pathogenic mycobacteria.
M.smegmatis is strictly a non-spore former. It neither forms spores nor capsules.
Mycobacterium smegmatis typically does not grow on bile esculin agar, as this medium is designed primarily for the isolation of Enterococcus and some other bile-tolerant organisms. Mycobacteria, including M. smegmatis, generally require specialized media for optimal growth due to their unique cell wall structure and nutrient needs. Therefore, while M. smegmatis might survive in some cases, it is unlikely to exhibit significant growth on this agar.
Mycobacterium smegmatis is a fast-growing species of mycobacteria, but it is not acid-fast like the pathogenic mycobacteria such as Mycobacterium tuberculosis. Acid-fast staining is a characteristic feature of mycobacteria that have a waxy lipid layer in their cell wall, which makes them resistant to staining by conventional methods.
Mycobacterium smegmatis is a non pathogenic organism so it is used in labs to study about Mycobacterium tuberculosis .
No, Mycobacterium smegmatis does not form endospores. Endospores are typically formed by some bacterial species in response to harsh environmental conditions as a survival mechanism, but Mycobacterium species, including M. smegmatis, do not produce endospores.

Mycobacterium Smegmatis is a bacilli bacteria. It is rod shaped.
M.smegmatis is strictly a non-spore former. It neither forms spores nor capsules.

All Mycobacteria are non-flagellated. Originally thought to be non-motile, it has recently been discovered M. smegmatis and other species of Mycobacteria move using a sliding mechanism in which the organism flattens and retracts to move.
The reason we use IS6110 for the identification of TB using procedures such as RFLP and Spoligotyping for several years now is because this is a genetic insertion sequence (IS) or element that is found exclusively within the members of the Mycobacterium tuberculosis complex (MTBC). Some researchers have found IS6110-like elements in some other mycobacteria such as M. smegmatis but because smegmatis do not cause TB, its clinical importance is lesser. This info was taken from "IS6110 is found in non-M. tuberculosis complex species" by Coros A, DeConno E, and Derbyshire KM, from the Wadsworth Center, NY, NY, (AMS March 7, 2008)
Yes, Mycobacterium smegmatis is positive for acid-fast staining due to its thick, waxy cell wall. This characteristic allows it to resist decolorization by acid-alcohol during the staining process, leading to retention of the primary stain (carbol fuchsin) and appearing pink or red under a microscope.

Mycobacterium pinnipedii was created in 2003.
