Purpose: To evaluate the performance of the Combination Double Disc Method in the identification of ESBL-producing Enterobacteriaceae isolates. Materials and Methods: A total of 44 clinically relevant Enterobacteriaceae isolates were examined. The ESBL classification furnished by Combination Double Disc Test Method was concordant with that of the comparison method (Etest ESBL and molecular iden...
Extended-spectrum beta-lactamase (ESBL)-producing pathogens are emerging as a cause of urinary tract infections (UTI) worldwide. In this matched-case control study, clinical characteristics and associated risk factors for ESBL UTI were evaluated. In a total of 463 positive urine cultures, 48 (10.4%) (from 39 patients, 23 boys) were phenotypically ESBL-producing bacteria. The most frequently iso...
This study evaluated the added value of selective preenrichment for the detection of rectal carriage of extended-spectrum-beta-lactamase-producing Enterobacteriaceae (ESBL-E). ESBL-E rectal carriage was identified in 4.8% of hospitalized patients, and 25.9% of ESBL-E rectal carriers were identified with selective preenrichment only.
مقدمه: امروزه ظهور ارگانیسمهای مولد آنزیم بتالاکتاماز وسیعالطیف(ESBL) یکی از معضلات درمانی به شمار میروند. بتالاکتامازهای وسیعالطیف از جمله آنزیمهایی هستند که عامل ایجاد مقاومت نسبت به آنتیبیوتیکهای بتالاکتام محسوب میشوند. هدف از این مطالعه تعیین الگوی مقاومت آنتیبیوتیکی و فراوانی ژنهای SHV و SHV-1 در سویههای اشریشیاکلی مولد آنزیم بتالاکتاماز وسیعالطیف جدا شده از افراد مبتلا به عف...
Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae are the leading causes of hospital-associated infections, but community-acquired cases are increasingly being reported. This study determined the prevalence of ESBL-producing E. coli and K. pneumoniae carriers, their bla genes and risk factors of 452 patients admitted to the emergency room (ER) of Ramathib...
Results of a 2003 survey carried out in Italy to evaluate the prevalence of extended-spectrum beta-lactamase (ESBL)-producing enterobacteria are presented. Eleven Italian Microbiology Laboratories investigated 9,076 consecutive nonreplicate isolates (inpatients, 6,850; outpatients, 2,226). ESBL screening was performed by MIC data analysis. Confirmation was obtained using the double-disk synergy...
Objective: To analyze the clinical and economic impact of community-onset urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae requiring hospitalization. Methods: A retrospective cohort study that included all adults with a UTI K. were admitted to tertiary care hospital in Barcelona, Spain, between 2011 2015. Demographic, clinical, da...
The present study was conducted to gain insights into the occurrence and characteristics of extended-spectrum beta-lactamase- (ESBL-) producing Escherichia coli (E. coli) from drinking well water in the rural area of Laiwu, China, and to explore the role of the nearby pit latrine as a contamination source. ESBL-producing E. coli from wells were compared with isolates from pit latrines in the vi...
BACKGROUND AND PURPOSE Strains of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae have spread widely in Taiwan hospitals. In this study, we evaluated the in vitro antimicrobial activity of tigecycline against ESBL-producing Enterobacteriaceae, including Klebsiella pneumoniae, Serratia marcescens and Enterobacter cloacae. METHODS 104 confirmed ESBL-producing bacteria were ...
Ertapenem is active against extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae organisms but inactive against Pseudomonas aeruginosa and Acinetobacter baumannii. Due to a lack of therapeutic data for ertapenem in the treatment of ESBL bloodstream infections (BSIs), group 2 carbapenems (e.g., imipenem or meropenem) are often preferred for treatment of ESBL-producing Enterobacteria...
