Abstract Antibiotic resistance is becoming one of the threats to global health. This crisis has been attributed over-the-counter and overuse antibiotics leading bacteria gain ability resist survive even in presence antimicrobial agents. Escherichia coli ( E. ) major gram-negative that are representative indicators antibiotic resistance. One mechanisms gaining production extended-spectrum beta-l...
OBJECTIVES To assess risk factors for acquiring extended-spectrum β-lactamase-producing Gram-negative bacteria (ESBL+ GN) causing urinary tract infections (UTIs) in long-term care facilities (LTCFs). METHODS A prospective case-case-control study was carried out. In the first study, cases were defined as patients harbouring ESBL+ GN, while, in the second study, cases were defined as patients h...
Objectives: To reveal the prevalence and epidemiology of extended-spectrum β-lactamase (ESBL)- and/or plasmid AmpC (pAmpC)- and carbapenemase (CP) producing Enterobacteriaceae and vancomycin-resistant enterococci (VRE) across the Northern Dutch-German border region. Methods: A point-prevalence study on ESBL/pAmpC/CP producing Enterobacteriaceae and VRE was carried out in hospitalized patients i...
The presence of extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-E. coli) in food animals is a public health concern. This study aimed to determine prevalence of ESBL-E. coli on pig farms and to assess the effect of reducing veterinary antimicrobial use (AMU) and farm management practices on ESBL-E. coli occurrence on pig farms. During 2011-2013, 36 Dutch conventional pig farms...
Objective In recent years, infection caused by extended-spectrum beta-lactamase (ESBL)-producing organisms has become an important issue. However, comparative studies of the bacteremia caused by ESBL Enterobacteriaceae and non-ESBL Enterobacteriaceae are extremely rare in Japan. This study aimed to assess the risk factors and prognosis of patients with bacteremia due to ESBL Escherichia coli (E...
BACKGROUND The rate of infections due to extended-spectrum β-lactamase (ESBL)-producing Escherichia coli is growing worldwide. These infections are suspected to be related to increased mortality. We aimed to estimate the difference in mortality due to bloodstream infections (BSIs) with ESBL-positive and ESBL-negative E. coli isolates and to determine the molecular epidemiology of our ESBL-posit...
OBJECTIVE To report trends of extended spectrum beta lactamase (ESBL), multidrug resistant (MDR) ESBL and emergence of carbapenem resistant ESBL producing isolates of K. pneumoniae from Pakistan. METHODS Retrospective analysis of laboratory data was conducted (2002-2007). K. pneumoniae were isolated and identified from clinical samples using standard microbiological techniques. Antimicrobial ...
زمینه و اهداف: ژن های کدکننده آنزیم های esbl معمولاً برروی یک پلاسمید کانجوگیتیو قرار دارند اما بیشتر ژنهای esbl که اخیراً مطرح شده اند به طور مکرر در ساختارهای شبه اینتگرون یافت شده اند. هدف از این مطالعه بررسی نقش آنزیم های esbl و اینتگرونهای کلاس i و ii در ایجاد مقاومت به آنتی بیوتیک ها می باشد. مواد و روش کار: 58 کلبسیلا پنومونیه از ادرار، خون و زخم نمونه های بالینی بیمارستان کرمان جمع آوری گ...

Urinary tract infections (UTIs) due to extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae in children are becoming more frequent, and they are commonly treated initially with a second- or third-generation cephalosporin. We developed a murine model of ascending UTI caused by ESBL-producing Escherichia coli. Using this model, we investigated the renal bacterial burden, interleukin-...
