摘要
目的 :探讨超广谱β-内酰胺酶 (ESβLs)的检测技术及调查产ESβLs细菌的耐药情况。方法 :对486株肠肝菌科细菌用双纸片协同法和复合纸片法做表型确证实验进行检测。结果 :大肠埃希菌阳性率为31% ,克雷伯菌属阳性率为43 %。产ESβLs菌对10种常用抗生素耐药率明显高于非产酶菌株。结论 :选择准确快速的检测方法提高ESβLs的阳性检出率 。
Objective:To study the detection technique of extend-spectrum β-lactamases(ESβLs) and investigate the drug resistance of ESβLs Methods:486 isolates of Enterobacter were Detected by compound piece type confirm test and double disk synergy test.Results:The positive rate of Escherichia coli was 31%,and the positive rate of Klebsiella was 43%.The drug resistance rate of extend-spectrum β-lactamases positive strains on ten common use antibiotics was significant higher than that in the non-enzymegenous strains.Conclusion:It is important to select the accurate and rapid detection method for raising the positive rate of extend-spectrum β-lactamases.
