Jacobs and other researchers treated TB-infected mice with two standard drugs in the study.

雅各布斯和其他研究人员在研究中用两种标准药物治疗了感染结核病的小鼠。

Their analysis, just published in plos Neglected Tropical Diseases, revealed an oil which proved 30% more effective at killing trypanosome parasites than did diminazene aceturate, the standard anti-trypanosomal drug.

他们的分析结果最近刚在《公共科学图书馆·被忽视的热带疾病》杂志上发表，结果显示他们发现了一种油，这种油已被验证其杀死锥虫寄生虫的效果比标准的抗锥虫药物乙酰氨基苯酯要高出30%。

So, if we can no longer use the standard drugs for drug sensitive TB, we have to use the so called second line or third line drugs.

因此， 如果我们不能再使用药物敏感结核病的标准药物，我们就必须使用所谓的二线或三线药物。
