由多重耐药(MDR)铜绿假单胞菌引起的感染呈现上升趋势,特别是在危重患者中,导致相关感染的发病率和病死率增加。目前对MDR铜绿假单胞菌感染的治疗可选药物很少。2014年和2015年,美国f.a.欧洲药品管理局(ema.相继分别批准了头孢洛扎-他唑巴坦用于治疗复杂性尿路感染和腹腔感染2项适应证。该复合制剂与头孢他啶相比,对a.pC酶更稳定,对铜绿假单胞菌的青霉素结合蛋白(PBP)有较高的亲和力,可有效地穿透缺失孔蛋白的外膜蛋白,并在有外排泵存在的细胞周质中发挥抗菌作用。因此头孢洛扎-他唑巴坦可用于治疗MDR铜绿假单胞菌所致感染。但该复合制剂对产金属酶(MBL)的菌株无效。本文主要评估MDR和广泛耐药(XDR)铜绿假单胞菌对该药的耐药率、潜在的耐药基因、克隆结构,并比较不同药敏试验方法对测试头孢洛扎-他唑巴坦的准确性。
