摘要 目的探讨医院感染标本常见革兰阴性杆菌分布状况及耐药特征,以利于临床合理用药。方法采用VITEK-AMS32型全自动微生物分析仪进行菌株鉴定和K-B法进行药敏试验;按NCCLS推荐的标准纸片扩散法测定超广谱β-内酰胺酶(ESBLs)。结果在临床分离出的942株革兰阴性杆菌中铜绿假单胞菌居首位241株(25.6%),其次是大肠埃希菌199株(21.1%)和肺炎克雷伯菌163株(17.3%)等;细菌ESBLs测定结果肺炎克雷伯菌和大肠埃希菌ESBLs检出率分别为34.2%和25.3%;亚胺培南、哌拉西林/三唑巴坦、阿米卡星、头孢他啶和头孢吡肟对多数革兰阴性杆菌抗菌作用良好,但嗜麦芽窄食单胞菌对大多数抗生素耐药。结论了解常见致病菌菌群分布及耐药性特点,有助于临床根据不同情况合理、安全选用抗生素,对控制医院感染至关重要。
