The high prevalence of this disease in Navajo populations was studied by Walsh McDermott, (-5[1])who pioneered a drug for it activated by KatG. An ELISpot-based assay for this (10[1])disease involves adding the antigens CFP-10 and ESAT-6 to a blood sample. A regime that includes rifampin (10[2]-5[2])and (10[3])isoniazid (10[4])is the first-line treatment (10[1])for the disease, (10[3])which can be tested for by measuring the size of a wheal (10[1])after injecting (10[3])purified protein derivative into the (10[1])skin. (10[10])This disease (10[2])can be (10[1])detected (10[3])with QuantiFERON (10[3])and (10[1])other interferon-gamma (10[2])release assays. (-5[1])The BCG vaccine (10[1]-5[1])is most (10[1])commonly used (10[1])for this disease, (10[4]-5[1])but may produce false positives (10[1])in Mantoux (10[3])tests (10[2])used to diagnose it. For 10 points, a species of Mycobacterium (10[1])causes a (10[1])bloody (10[1])cough in what (10[2])infectious (-5[1])lung disease (10[2])historically (10[1])called consumption? (10[2])■END■ (10[8])
