Bacterial keratitis causes significant blindness, yet antimicrobial resistance has rendered current treatments ineffective. Polymyxin B-trimethoprim (PT) plus rifampin has potent activity against and , two important causes of keratitis. Here we further characterize this combination against in a murine keratitis model. PT plus rifampin performed comparably to or better than moxifloxacin, the gold standard, suggesting that the combination may be a promising therapy for bacterial keratitis.
细菌性角膜炎可导致严重失明,但抗菌药物耐药性已使目前的治疗方法失效。多粘菌素 B-三甲氧苄啶(PT)加利福平对 和 具有很强的活性,这两种是角膜炎的重要病因。在这里,我们在小鼠角膜炎模型中进一步研究了这种联合用药对 的作用。PT 加利福平的疗效与莫西沙星(金标准)相当或更好,这表明该联合用药可能是治疗细菌性角膜炎的一种有前途的疗法。
