| 摘 要： | 目的探讨盐酸氨溴索（Ambroxol Hydrochloride,Amb）联合左氧氟沙星（Levofloxacin,LFX）对粘液型铜绿假单胞菌生物被膜（biofilm,BF）的影响。方法以铜绿假单胞菌粘液型菌株PDO300为实验菌株,构建体外BF模型。分为生理盐水对照组、Amb组、LFX组、Amb与LFX联合作用组,二倍稀释法测定LFX最低杀菌浓度（minimum bactericidal concentration,MBC）,结晶紫染色法定量测定BF形成量。结果 PDO300培养7d后可形成稳定的BF。与单独应用LFX相对比,Amb与LFX联合作用后测定载体表面BF值显著降低（P〈0.01）,且载体表面BF随着LFX浓度增高而减少。结论 Amb可显著增强LFX对BF的破坏作用。
