Extended spectrum β-lactamase (ESBL) producing Escherichia coli has tremendously increased worldwide and it is one of the most common causes of morbidity and mortality associated with hospital-acquired infections. This could be attributed to association of multi drug resistance in ESBL producing isolates. The present study was aimed to determine the antimicrobial sensitivity profile of ESBL producing E. coli isolates from various clinical samples.
Clinical samples, which consist of pus, urine, blood, cerebrospinal fluid (CSF), stool, sputum, swabs, and different body fluids, are included in the study. Samples were processed and identified as per routine laboratory protocol. ESBL screening and confirmation along with antimicrobial susceptibility test was done according to the Clinical Laboratory Standards Institute (CLSI) guidelines.
Out of 180 third generation cephalosporins resistant E. coli, 100 (55.55%) isolates were ESBL producers showing a greater degree of resistance to antibiotics.
The prevalence of ESBL is increasing day by day in nearly every center of different countries and necessary steps to prevent the spread and emergence of resistance should be taken.
产超广谱β-内酰胺酶(ESBL)的大肠埃希菌在全球范围内大幅增加,它是医院获得性感染相关发病和死亡的最常见原因之一。这可能归因于产ESBL菌株中多重耐药性的关联。本研究旨在确定从各种临床样本中分离出的产ESBL大肠埃希菌的抗菌敏感性谱。
本研究纳入了由脓液、尿液、血液、脑脊液(CSF)、粪便、痰液、拭子和不同体液组成的临床样本。样本按照常规实验室方案进行处理和鉴定。根据临床实验室标准协会(CLSI)指南进行ESBL筛查和确认以及抗菌药物敏感性试验。
在180株对第三代头孢菌素耐药的大肠埃希菌中,100株(55.55%)分离株产ESBL,对抗生素表现出更高程度的耐药性。
在不同国家的几乎每个中心,ESBL的流行率都在日益增加,应采取必要措施防止耐药性的传播和出现。
