Multiple Drug Resistant Tuberculosis (MDR-TB) 
(En español)
A form of tuberculosis (TB) that is resistant to the two most effective antibiotics commonly used to cure TB infection (isoniazid and rifampin). People infected with multiple drug resistant-TB (MDR-TB) are at high risk for treatment failure. They are also at risk for further drug resistance, which can lead to life-threatening disease—extensively drug resistant tuberculosis (XDR-TB).
