摘要 目的:比较不同β酰胺类抗生素与其酶抑制剂复方制剂对超广谱β酰胺酶(ESBLs)产生菌、非产酶菌及其他细菌的体外抗菌活性。方法:应用K-B纸片扩散法,分别观察阿莫西林/克拉维酸,头孢哌酮/舒巴坦,哌拉西林/三唑巴坦、头孢哌酮、哌拉西林等5种抗生素制剂对大肠埃希菌和肺炎克雷伯菌ESBLs产生株及非产酶株等细菌的体外抗菌作用。结果:β内酰胺类抗生素与其酶抑制剂复方制剂与不含酶抑制剂的抗生素制剂对大肠埃希菌和肺炎克雷伯菌ESBLs产生株与非产酶株的抗菌作用差异具有非常显著性(P<0.001),并显示:不同的含酶抑制剂复方制剂对不同种类产酶菌的抗菌活性不同;含酶抑制剂与不含酶抑制剂两组抗生素制剂对阴沟肠杆菌抗菌活性存在一定的差异,而对铜绿假单胞菌作用差异无显著性(P>0.05)。结论:β酰胺类抗生素与其酶抑制剂的复方制剂对产ESBLs菌的抗菌活性显著增强,但对铜绿假单胞菌抗菌作用的增强不显著,可能与产酶类型不同及产ESBLs不是该菌的主要耐药机制等因素有关。
