BACKGROUND & OBJECTIVES Urinary tract infection (UTI) remain the common infections diagnosed in outpatients as well as in hospitalized patients. Current knowledge on antimicrobial susceptibility pattern of uropathogens is mandatory for appropriate therapy. Extended spectrum beta lactamases (ESBL) hydrolyse expanded spectrum cephalosporins like ceftazidime, cephotaxime which are used in the trea...
زمینه و هدف: به دلیل طبیعت منحصر به فرد، توانایی زنده ماندن در محیطهای مرطوب و مقاومت ذاتی به بسیاری از آنتیبیوتیکها و آنتیسپتیکها، سودوموناس آئروژینوزا پاتوژن شایع در بیمارستان به ویژه در بخشهای مراقبت ویژه است. اهداف این مطالعه شناسایی سودوموناس آئروژینوزا دارای ژن blaCTX ایجادکننده عفونت در بیمارستان، تعیین الگوی حساسیت آنتیبیوتیکی آنها و بررسی توانایی تولید آنزیمهای بتالاکتاماز وس...
زمینه و اهداف: با توجه به اهمیت گزارش‌های فراوان از عفونت‌های ناشی از اسینتوباکتر بومانی مولد بتالاکتامازهای وسیع الطیف در سال‌های اخیر در کشورمان، این مطالعه باهدف تعیین مقاومت پادزیستی و تعیین فراوانی ژنهای کد کننده ی بتالاکتامازهای PERو VEB در ایزوله ی اسینتوباکتر بومانی از بیماران بیمارستانهای تهران با روش PCR انجام شد. مواد و روش کار: 100 ایزوله ی بالینی اسینتوباکتر بومانی جمع آوری شده ...
Hypermutable (mutation frequency [f], > or = 4 x 10(-8)) Escherichia coli strains were more frequently found (43%) in a collection of 89 extended-spectrum beta-lactamase (ESBL)-producing isolates from different patients (77 pulsed-field gel electrophoresis clones, 12 ESBL types) than in non-ESBL E. coli (26%) strains (P = 0.03). Among urinary tract isolates, the frequency of hypermutation was 4...
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...
