摘要 铜绿假单胞菌是人体的一种条件致病菌,目前在我国医院获得性感染中占有非常重要的地位,并且随着抗菌药物的广泛应用,其对亚胺培南的耐药率逐年上升,这给临床抗感染治疗带来了很大的困难.目前认为铜绿假单胞菌对亚胺培南的耐药机制主要有如下几个方面:β-内酰胺酶的水解作用、细菌外膜孔蛋白的通透性降低、作用靶位(如青霉素结合蛋白)的改变、主动外排系统高表达、生物膜的产生等[¨].本实验室前期对广州市收集的亚胺培南耐药的铜绿假单胞菌产金属β-内酰胺酶的情况进行了研究,在此基础上,本研究对这些菌株进行了OprD和青霉素结合蛋白(penicillinbinding proteins,PBPs)这两方面的检测,以全面了解广州地区铜绿假单胞菌分离株对亚胺培南的耐药机制.
