INTRODUCTION Bloodstream infections (BSIs) are serious diseases associated with high mortality, especially when caused by extensively drug-resistant (XDR) Klebsiella pneumoniae. The prevalence and pandemic strains of extended-spectrum beta-lactamase (ESBL)-producing K. pneumoniae isolated from blood cultures of patients with BSIs were determined at Sir Run Run Shaw Hospital, China. METHODOLOG...
Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the de...
Background: Extended spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) are a serious challenge to patients’ treatment. The aim of this study is determine the prevalence ESBL-PE, investigate associated resistance, and analyze risk factors for acquisition ESBL-PE.Methodology: A cross-sectional was conducted on healthy volunteers inpatients. After obtaining informed consent, rectal sw...
BACKGROUND Studies about transmission rates of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in hospitals and households are scarce. METHODS Eighty-two index patients with new carriage of ESBL-producing Escherichia coli (ESBL-Ec; n = 72) or ESBL-producing Klebsiella pneumoniae (ESBL-Kp; n = 10) and their hospital (n = 112) and household (n = 96) contacts were studied prosp...
OBJECTIVE To determine the prevalence of extended-spectrum beta-lactamase (ESBL) producing Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E. coli), risk factors of ESBL-producing strains and antimicrobial susceptibility pattern of ESBL-producing and non producing strains. METHODS The study took place at the Faculty of Medicine, Osmangazi University, Eskisehir, Turkey from March t...
AIMS Diabetic foot lesions are a major medical, social, and economic problem and are the leading cause of hospitalization for patients with diabetes, worldwide. ESBL-producing bacteria may not be detectable by routine disc diffusion susceptibility test, leading to inappropriate use of antibiotics and treatment failure. There is not much information on ESBL-producing organisms causing diabetic f...
The prevalence and molecular types of extended-spectrum beta-lactamases (ESBLs) were determined during a 1-year period in unselected clinical nonduplicate isolates of Escherichia coli (n = 1,738), Klebsiella pneumoniae (n = 436), and Klebsiella oxytoca (n = 208), cultured at the University Medical Centre Nijmegen, The Netherlands. Isolates identified as ESBL producer by the Phoenix automated sy...
BACKGROUND Proteus species cause a variety of community- and hospital-acquired illnesses. Synthesis of β-lactamases is the predominant mechanism for resistance to β-lactam antibiotics. Among the β-lactamases, extended spectrum β-lactamases (ESBLs) and AmpC β-lactamases are the most common. AIM The objective of this study was to determine the occurrence of ESBL and AmpC β-lactamases in Proteus...
OBJECTIVES Extended-spectrum beta-lactamase (ESBL) producing bacteria have an important role in nosocomial infections. Due to the limited availability of information about the molecular epidemiology of ESBL producing bacteria in Mashhad, we decided to investigate about TEM, CTX and SHV ESBLs among urinary Escherichia coli isolates in Mashhad, a city in northeast Iran. MATERIALS AND METHODS On...
BACKGROUND 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 ...
