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). The bacteria that cause tuberculosis (TB) are classified as mycobacteria. To diagnosis widespread MAC infection, doctors usually try to grow (culture) the bacteria from a sample of blood or from tissue taken from the bone marrow, the liver, or an infected lymph node.
