摘要 目的了解对头孢噻肟耐药的大肠埃希菌产超广谱β-内酰胺酶(ESBLs)、超超广谱β-内酰胺酶(SSBL)的临床分布及其对抗生素的敏感性。方法利用双纸片协同试验及纸片法确证试验检测ESBLs及SSBL,并用纸片扩散试验和DL-96E测定抗生素的敏感性。结果从头孢噻肟最小抑菌浓度(MIC)≥2的大肠埃希菌检出产ESBLs为62.5%;产SSBL为9.4%。产酶菌株对头孢菌素高度耐药,对氨曲南、庆大霉素、环丙沙星及复方新诺明耐药率高,对亚胺培南、美罗培南、哌拉西林/他唑巴坦、阿米卡星、头孢哌酮/舒巴坦耐药率低。结论产生ESBLs、SSBL是大肠埃希菌对头孢菌素类抗生素耐药的重要机制,实验室应加强检测,为临床合理使用抗生素提供依据。
