Abstract

Introduction: Escherichia coli (E.coli) as a main cause of both nosocomial and communityacquired infections in humans have a relative potential to develop resistance. Nowadays, most infections caused by ESBL-producing E.coli (ESBLEC) had mostly been described as nosocomial acquired or nursing home related. In this study, we employed E-test assay to detect antibiotic resistance of E.coli strains and determine MIC of antibiotics. Materials and methods: Thirty E.coli strains gathered from Imam Khomeini hospital of Ilam, and cultured on TSB and bacterial suspension prepared by 0.5 μF concentration for Etest. Mueller Hinton agar and E-test strips of Amikacin, Cefepime, Ceftazidime, Ceftriaxone, Gentamicin, Meropenem, Nitrofurantoin, Piperacillin/Tazobactam, Tetracycline, Ticarcillin/ Clavulanic acid, Tobramycin, Trimethoprim were used Results: Resistance to Ceftriaxone, Tobramycin, Gentamicin, Ticarcillin/ Clavulanic, Amikacin were 19.8%, 26.4%, 23.3%, 62.7%, 70.3%, respectively. Conclusion: the results indicated, E.coli strains in this study were high sensitivity to Meropenem ,Nitrofuratoin, Ciprofloxacin , Ceftazidime, Cefepime.

伊朗伊玛目霍梅尼医院医院获得性感染分离大肠杆菌的e -试验抗生素敏感性
简介:大肠杆菌(E.coli)作为人类院内和社区获得性感染的主要原因,具有相对的耐药潜力。目前,大多数由产esblc大肠杆菌引起的感染大多被描述为医院获得性或养老院相关。在本研究中,我们采用E-test法检测大肠杆菌菌株的耐药性,并测定抗生素的MIC。材料与方法:从伊朗伊玛目霍梅尼医院采集30株大肠杆菌,在0.5 μF浓度的TSB和菌悬液上进行培养。结果:对头孢曲松、妥布霉素、头孢他啶、头孢曲松、庆大霉素、美罗培南、呋喃妥英、哌拉西林/他唑巴坦、四环素、替卡西林/克拉维酸、妥布霉素、甲氧苄啶的耐药率分别为19.8%、26.4%、23.3%、62.7%、70.3%。结论:本研究大肠杆菌对美罗培南、呋喃呋喃、环丙沙星、头孢他啶、头孢吡肟均有较高的敏感性。
