Mycobacterium
Mycobacterial infections are complex diseases and are more common in individuals with weakened immune systems, for example people undergoing treatment for cancer or that are HIV positive. One third of the planet’s population currently carries the M. tuberculosis bacteria. However, only 25 per cent will develop disease. They can cause tuberculosis, nontuberculous mycobacteria (NTM) pulmonary infections, other localized NTM or disseminated infections, leprosy, and chronic ulcers (Buruli ulcer).
