Mycobacterium tuberculosis (M. tb) is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. Whilst these pathogenic species exhibit some phenotypic differences, they are genetically very similar and are therefore often classed as the ‘ Mycobacterium tuberculosis complex’. While antibiotic resistance is cited as a potential threat to efforts aimed at controlling the spread of this pathogen, it is not clear how drug resistance affects disease dynamics. Nontuberculous mycobacteria (NTM) is a group of bacteria, normally found in soil and water and some domestic and wild animals, that can cause severe lung disease. As a consequence, Mtb resides in a mildly acidic compartment and is exposed to reactive oxygen intermediates (ROI) from phagocyte oxidase (NOX2). These bacteria exist naturally in soil and water and are not necessarily the cause of disease.
