The activities of rifampin, nitazoxanide, PA-824, and sutezolid were tested against dormant under conditions mimicking caseous granulomas (hypoxia at pH 7.3) in comparison with those of the combination rifampin-isoniazid-pyrazinamide-ethambutol (R-I-Z-E), which is used for human therapy. Mycobacterial viability was monitored by CFU and regrowth in MGIT 960. As shown by lack of regrowth in MGIT, rifampin-nitazoxanide-containing combinations, but not R-I-Z-E, killed dormant cells in 28 to 35 days. These observations might be important in designing new tuberculosis therapies.
利福平、硝唑尼特、PA-824 和苏替唑利的活性在模拟干酪样肉芽肿(低氧 pH7.3)的条件下进行了测试,并与用于人类治疗的利福平-异烟肼-吡嗪酰胺-乙胺丁醇(R-I-Z-E)组合进行了比较。通过 CFU 和 MGIT960 中的再生长监测分枝杆菌的活力。如 MGIT 中无再生长所示,含有利福平-硝唑尼特的组合,而不是 R-I-Z-E,可在 28 至 35 天内杀死休眠细胞。这些观察结果在设计新的结核病治疗方法方面可能很重要。
