阴沟肠杆菌产AmpC酶和ESBLs的检测及其耐药机制研究

Zhongguo shiyan zhenduanxue, 2010
目的了解阴沟肠杆菌临床分离株AmpC酶和ESBLs的产生情况并分析其耐药特性,为临床合理使用抗菌药物提供依据。方法采用改良的酶提出物三维试验法对186株阴沟肠杆菌进行AmpC酶和ESBLs检测,用K-B法对14种常用抗菌药物进行药物敏感试验。结果 186株阴沟肠杆菌中,产AmpC酶的菌株63株,占33.9%;产ESBLs的菌株有28株,占15.1%;同时产AmpC酶和ESBLs的菌株有18株,占9.7%。药敏结果显示,186株阴沟肠杆菌对头孢唑林、氨苄西林、头孢西丁等抗菌药物的耐药率较高,对亚胺培南 ...

中国鱼类病原菌耐药质粒

, 1999
通过细菌接合试验，从 ３１ 株鱼类病原菌中检测到 １ 株含有可自身传递的耐药质粒，命名为 ｐ Ｗ Ｈ１０１。该质粒具有四环素和磺胺 ２ 种抗性，经溴化乙锭处理，获得了该质粒被消除的抗性敏感株。质粒提取及电泳试验也证实了该质粒的存在，其分子量约为 １０７ ｋｂ
