Initial drug resistance profile | Description of drug-resistance profile† |
---|---|
Drug sensitive | Initially sensitive to both isoniazid and rifampin |
Isoniazid resistance without MDR TB | Initially resistant to isoniazid and sensitive to rifampin |
Rifampin resistance without MDR TB | Initially resistant to rifampin and sensitive to isoniazid |
