Definition of abbreviations: H = isoniazid; M = moxifloxacin; P = rifapentine; R = rifampin; Z = pyrazinamide.
Drugs were given orally at the following doses: H, 25 and 50 mg/kg when administered daily (5 out of 7 days [5/7]) and thrice-weekly (3/7), respectively; R, 10 mg/kg; Z, 150 and 225 mg/kg when administered 5/7 and 3/7, respectively; M, 100 mg/kg; P, 10, 15, and 20 mg/kg, as indicated.
Months 8 (+3), 10 (+3), and 12 (+3) indicate that mice were killed 3 months after completing 8, 10, and 12 months of treatment.
