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 :آنتی بیوتیک های بتالاکتام به طور گسترده ای در درمان سالمونلوز مورد استفاده قرار می گیرند. گزارشات هشدار دهنده توسعه سریع مقاومت در برابر این عوامل، شامل سرووار های سالمونلا مانند انتریتیدیس، تیفی موریوم، پاناما و تیفی را در چند کشور اشاره کرده اند. هدف از این مطالعه، بررسی پروفایل مقاومت آنتی بیوتیکی و شیوع ژن blatem و blapse سالمونلا تیفی موریوم در انسان در تهران بود. مواد و روش...
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-...
The dissemination of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) from food-producing animals to the surrounding environment has attracted much attention. To determine the emissions of ESBL-producing E. coli from pig farms to the surrounding environment, fecal and environmental samples from six pig farms were collected. In total, 119 ESBL-producing E. coli were isol...
چکیده زمینه و هدف: تولید آنزیمهای بتالاکتاماز توسط باکتریها بهویژه نوع Extended Spectrum β-Lactamase (ESBL) یکی از مشکلات بهداشتی و درمانی در سطح دنیاست. شیوع این آنزیمها در نواحی جغرافیایی مختلف و با زمان تغییر میکند. هدف از انجام این تحقیق، تعیین شیوع باکتریهای مولد بتالاکتاماز وسیع الطیف در میان ایزولههای ادراری انتروباکتریاسه و ردیابی ژن blaPER در دو بیمارستان منتخب مشهد بوده است. م...
