目的:探讨医院产超广谱β-内酰胺酶(ESBLs)大肠埃希菌的临床感染分布及耐药情况,为临床抗感染治疗合理选择抗生素、减少耐药发生提供依据。方法:收集2010年8月-2011年12月从临床送检标本中分离的大肠埃希菌264株,药敏试验采用K-B纸片扩散法。根据美国临床检验室标准化委员会(CLSI)推荐的纸片扩散法,严格按照其制定的标准进行ESBLs确证实验。采用WHONET 5.4软件进行统计学分析。结果:264株大肠埃希菌中检出134株(50.8%)产ESBLs大肠埃希菌,标本分布以痰标本最高(47.76%),而科室分布以普外科最高(12.61%)。在药敏实验中,产ESBLs菌株对亚胺培南、美罗培南、头孢哌酮/舒巴坦、阿米卡星、哌拉西林/他唑巴坦、呋喃妥因、头孢西丁的耐药性较低(0%~15.5%);环丙沙星、左氧氟沙星、庆大霉素、复方新诺明,阿莫西林/克拉维酸的耐药性较高(41.3%~82.8%);青霉素类、头孢菌素类及ATM耐药性高(100%),临床不宜选用。结论:产ESBLs大肠埃希菌存在多重耐药性,临床实验室应加强产ESBLs菌株的监测,根据临床药敏结果合理选用抗生素。
目的:探討醫院產超廣譜β-內酰胺酶(ESBLs)大腸埃希菌的臨床感染分佈及耐藥情況,為臨床抗感染治療閤理選擇抗生素、減少耐藥髮生提供依據。方法:收集2010年8月-2011年12月從臨床送檢標本中分離的大腸埃希菌264株,藥敏試驗採用K-B紙片擴散法。根據美國臨床檢驗室標準化委員會(CLSI)推薦的紙片擴散法,嚴格按照其製定的標準進行ESBLs確證實驗。採用WHONET 5.4軟件進行統計學分析。結果:264株大腸埃希菌中檢齣134株(50.8%)產ESBLs大腸埃希菌,標本分佈以痰標本最高(47.76%),而科室分佈以普外科最高(12.61%)。在藥敏實驗中,產ESBLs菌株對亞胺培南、美囉培南、頭孢哌酮/舒巴坦、阿米卡星、哌拉西林/他唑巴坦、呋喃妥因、頭孢西丁的耐藥性較低(0%~15.5%);環丙沙星、左氧氟沙星、慶大黴素、複方新諾明,阿莫西林/剋拉維痠的耐藥性較高(41.3%~82.8%);青黴素類、頭孢菌素類及ATM耐藥性高(100%),臨床不宜選用。結論:產ESBLs大腸埃希菌存在多重耐藥性,臨床實驗室應加彊產ESBLs菌株的鑑測,根據臨床藥敏結果閤理選用抗生素。

Objective:To explore the distribution and antibiotic resistance of extended-spec-trum-β-lactamases(ESBLs)-producing Escherichia coli in the hospital,so as to provide reference for reasonable utilization of antibiotic and reducing of drug resistance. Methods:From Aug,2010 to Dec,2011,264 E.colis were isolated from clinical specimens,the antibiotic susceptibility was test-ed by K-B method. According to CLSI standard,ESBLs was confirmed,statistical analysis was tak-en with WHONET 5.4 software. Results:Among 264 E.coli isolates,134(50. 8%)were ESBLs-pro-ducing strains. The sputum was the highest sources of specimens(47. 76%),the department of gen-eral surgery was the highest section-office of distribution(12. 61%). The resistance rates for ES-BLs-producing E.coli to imipenem,meropenem,piperacillin/tazobactam,cefoperazone/sulbactam, amikacin,cefoxitin and nitrofurantoin were lower and between 0% to 15. 5%;The resistance rates to ciprofloxacin,levofloxacin,gentamicin,compound sulfamethoxazole and amoxicillin/clavulanate were higher and between 41. 3% to 82. 8%;The resistance rates to penicillins,cephalosporins and aztreonams were highest and reached 100%,so they are not suitable for clinic. Conclusion:ES-BLs-producing E.coli has multidrug-resistant,so it is necessary to strengthen the surveillance in clinical laboratory,to use antibiotics according to antibiotic susceptibility test.
