Introduction: Extended spectrum beta-lactamase (ESBL) producing Escherichia coli generate a major problem for clinical therapeutics and epidemiological study. The incidence of ESBL producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. The aim of this study was to determine the a...

Our study aims to investigate and describe the epidemiology of the intestinal carriage of ESBLPS in intensive care units of five Lebanese hospitals and to analyze the potential risk factors for the acquisition of these strains. At the same time, we intend to determine the patterns of susceptibility of these strains, exploring therefore the availability of alternative treatment. One thousand, fo...

Background Due to increasing colistin usage, the dissemination of the colistin-resistant gene mcr-1 has been increasingly investigated. The aim of this study was to determine whether a traveler on a short-term international trip to a developing country could bring mcr-1 back to their home country. Materials and methods Thirty-four travel events from Japan to Vietnam encompassing 19 travelers ...

BACKGROUND Infections by extended-spectrum beta-lactamase- (ESBL) and carbapenem-resistant Enterobacteriaceae (CRE) are an emerging problem in children nowadays. Hence, the aim of this study was to determine the prevalence of ESBL- and carbapenemase-producing Enterobacteriaceae among children suspected of septicemia and urinary tract infections (UTIs). METHODS A cross-sectional study was cond...

Objectives: Carbapenem-resistant Gram-negative bacilli are reported increasingly and represent an emerging public health concern. Laboratory detection of extended-spectrum b-lactamase (ESBL), plasmid-mediated cephalosporinase (pAmpC) and carbapenemase producers remains a challenge for microbiology laboratories and is important to avoid clinical failure due to inappropriate antimicrobial therapy...

Emergence of extended spectrum β lactamases (ESBLs) producing strains of gram negative bacteria, as one of the leading cause of septicemia often complicates the clinical and therapeutic outcome. The present study was undertaken to investigate the prevalence of ESBLs in bacteria isolated from neonatal septicemia cases along with their antimicrobial sensitivity pattern. Blood samples were collect...

Nine isolates of Klebsiella pneumoniae, obtained from one colonized and eight bacteraemic patients on a paediatric ward, were shown to be identical by PFGE, indicating an outbreak. Screening for extended-spectrum beta-lactamase (ESBL) production using the double-disc synergy test, Etest for ESBLs and agar diffusion tests indicated ESBL production. The isolates showed reduced susceptibility to c...

Introduction: Extended spectrum β-lactamases (ESBLs) are enzymes that degrade β-lactam antibiotics and have been reported to be an important cause of nosocomial infection in worldwide. Methods: During 2009, 659 enterobacteria strains were isolated from different clinical specimens and tested for ESBL production. The disk approximation test, combined disk method and addition of clavulanic acid w...

BACKGROUND & OBJECTIVES Non-fermenting Gram-negative bacilli (NFGNB) including Pseudomonas aeruginosa and Acinetobacter baumannii have been implicated in a variety of infections, particularly in the Intensive Care Units (ICUs). This study was aimed to overview the burden of multidrug-resistant NFGNB causing infections in ICU and also to assess the occurrence of extended-spectrum beta-lactamases...
