Multi-drug resistant tuberculosis (MDR-TB) is defined as disease caused by Mycobacterium tuberculosis that is resistant to at least rifampicin and isoniazid. It can be acquired primarily through direct infection or can develop secondarily through inadequate treatment of drug-susceptible TB (DS-TB). Its treatment is lengthy, complex and can cause severe side effects. MDR-TB is an emerging issue globally; in 2011, 630 000 of the 12 million prevalent TB cases were MDR [1].
