Apart from its ability to grow faster, M. smegmatis has a similar cell wall Mycobacterium smegmatis is a common microorganism which, for a number of reasons, has become one of the most important bacteria for biological study. In the saprophytic organism Mycobacterium smegmatis, Ald is a cytosolic protein and is overproduced under anaerobic conditions which mimic the dormancy state of M. tuberculosis (14, 22, 32, 43). integrate into the Mycobacterium genome or even lysogenize at all. Mycolicibacterium smegmatis is a rapid-growing bacterium and previously belonged to the genus Mycobacterium as basonym Mycobacterium smegmatis, to which many pathogenic mycobacteria, including M. tuberculosis, a causative agent of tuberculosis, and M. leprae, a causative agent of leprosy, are belonging (Gupta et al., 2018; Oren and Garrity, 2018). They are aerobic, non-spore forming, non-motile, slightly curved or straight rods (0.2 to 0.6 μm by 1.0 to 10 μm) which may branch. You are using a browser version with limited support for CSS.

Discovery of new anti-tuberculosis (TB) drugs is a time-consuming process due to the slow-growing nature of Mycobacterium tuberculosis (Mtb). 2015;68:271–8. We show that a range of microorganisms, including environmental species, Escherichia coli, and Mycobacterium smegmatis, indeed wake up in a seemingly stochastic manner and independently of environmental conditions, even in the longest incubations conducted (months to years long). The sensitivity and clinical utility of any NAT strategy relies on the availability of nucleic acids in a sample. M. smegmatis was proposed as a surrogate for M. tuberculosis because the latter is a hazardous group 3 contaminant, which requires a biosafety level 3 work setting.
