aMDR TB is tuberculosis that is resistant to isoniazid and rifampin. Pre-XDR TB is tuberculosis that is resistant to isoniazid, rifampin, and either a quinolone or an injectable agent. XDR TB is tuberculosis that is resistant to isoniazid, rifampin, quinolone, and injectibale agent.
Abbreviations: HIV, human immunodeficiency virus; MDR, multidrug resistant; TB, tuberculosis; XDR, extensively drug resistant.
