Abstract
The impact of quorum sensing on polymyxin and azithromycin pharmacodynamics was assessed in PAO1 and an isogenic / double knockout. For polymyxin B, greater killing against the / knockout than against PAO1 was observed at 10 CFU/ml (polymyxin B half-maximal effective concentration [EC], 5.61 versus 12.5 mg/liter, respectively; < 0.005). Polymyxin B combined with azithromycin (256 mg/liter) was synergistic against each strain, significantly reducing the respective polymyxin B EC compared to those with monotherapy ( < 0.005), and is a promising strategy by which to combat .
摘要
在铜绿假单胞菌PAO1及其同基因/双敲除菌株中评估了群体感应对多粘菌素和阿奇霉素药效学的影响。对于多粘菌素B，在10 CFU/ml时观察到对双敲除菌株的杀灭作用比对PAO1更强（多粘菌素B的半数有效浓度[EC]分别为5.61和12.5 mg/升；P<0.005）。多粘菌素B与阿奇霉素（256 mg/升）联合使用对每种菌株都具有协同作用，与单药治疗相比，显著降低了各自的多粘菌素B的EC（P<0.005），这是一种对抗[相关疾病]的有前景的策略。
