摘要 目的:评价4种超广谱β-内酰胺酶(ESBLs)筛选方法检测产ESBLs大肠埃希菌和肺炎克雷伯菌的可靠性。方法:以头孢哌酮、头孢他啶和氨曲南为指示底物,用双纸片协同试验、三维试验、双纸片增效试验和E-test法4种方法检测32株ESBLs阳性和45株ESBLs阴性大肠埃希菌和肺炎克雷伯菌产生情况。结果:4种方法的敏感性分别为93.75%、96.87%、87.50%和96.87%,特异性分别为97.78%、95.56%、100%和100%。头孢他啶和头孢哌酮为本院检测ESBLs最适指示底物。结论:三维试验和E-test法是4种检测方法中检测产ESBLs最可靠的方法,三维试验检测产ESBLs菌株适合小型医院,双纸片协同试验和双纸片增效试验在所有医院都适合应用。
