摘要 目的研究瑞安市人民医院临床标本分离出的的阴沟肠杆菌产AmpC酶和超广谱β-内酰胺酶(ESBLs)情况,以指导临床用药。方法收集瑞安市人民医院2006年1~12月临床标本分离到的96株阴沟肠杆菌,用纸片扩散法对14种抗菌药物进行了药敏试验,用改良三维试验进行持续高产AmpC酶和ESBLs的双重检测。结果96株阴沟肠杆菌中11株(11.5%)高产AmpC酶;2株(2.1%)既持续高产AmpC酶又产ESBLs;40株(41.6%)只产ESBLs;其余43株(44.8%)未发现持续高产AmpC酶或ESBLs。结论使用改良的酶提取物三维试验可同时检测高产AmpC酶和ESBLs菌株,应根据阴沟肠杆菌产生不同的ESBLs来选择性用药。
