BACKGROUND Extended spectrum beta lactamases (ESBLs) are an important cause of transferable multidrug resistance (MDR) in gram-negative bacteria. The most described ESBL genes are generally found within integron-like structures as mobile genetic elements. The aim of this study was to identify the accompanying of class 1 integrons and ESBLs in the MDR E. coli isolates. METHODS Susceptibility t...

INTRODUCTION Few reports about the prevalence and genetic basis of extended spectrum beta-lactamases (ESBLs) are available from Saudi Arabia. We sought to determine the prevalence of ESBL-producing Enterobacteriaceae in a university hospital in eastern Saudi Arabia and to characterize the ESBLs produced by these isolates at the molecular level. METHODOLOGY All clinical isolates of Escherichia...

Background: The isolation of the TEM gene in Pseudomonas aeruginosa and Escherichia coli and the antibiotic resistance pattern provides useful information on the epidemiology and factors involved in these infections. Aim: The aim of this study was to evaluate antibiotic resistance and abundance of a beta-lactamase gene (TEM) in P.aeruginosa and E.coli isolated from clinical specimens by the po...

BACKGROUND/PURPOSE The emergence of multiple drug resistance in Enterobacteriaceae is of particular concern. The aim of this study was to evaluate the antimicrobial susceptibility and screen for the ampC gene in three members of the Enterobacteriaceae family (Enterobacter cloacae, Citrobacter freundii, and Serratia marcescens) found at Taichung Veterans General Hospital during the past 5 years ...

BACKGROUND & OBJECTIVES Information about the genetic diversity of the extended-spectrum β-lactamases (ESBLs) and the clonal relationship of the organisms causing neonatal infections is limited, particularly from India where neonatal mortality is high. This study was undertaken to investigate the molecular epidemiology and risk factors associated with neonatal septicaemia caused by ESBL-produci...

Biodiversitas 23: 4256-4262. Antimicrobial resistance (AMR) has become a severe threat worldwide and its remote cause remains unclear in most parts due to the global emergence new mechanisms by micro...

The increase of extended- spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) in humans and in food-producing animals is of public health concern. The latter could contribute to spreading of these bacteria or their resistance genes to humans. Several studies have reported the isolation of third generation cephalosporin resistant bacteria in livestock animals. However, the number of sampl...

BACKGROUND Extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-PE) are increasingly reported as pathogens in urinary tract infections (UTIs). However, in Sri Lanka, the clinical and molecular epidemiology of ESBL-PE implicated in UTIs has not been well described. MATERIALS AND METHODS We conducted prospective, laboratory-based surveillance from October to December 2013 at a terti...

BACKGROUND Faecal carriage of ESBL-producing bacteria is a potential risk for transmission and infection. Little is known about faecal carriage of antibiotic resistance in Tanzania. This study aimed to investigate the prevalence of faecal carriage of ESBL-producing Enterobacteriaceae and to identify risk factors for carriage among young children in Tanzania. METHODOLOGY/PRINCIPAL FINDINGS Fro...

conclusions the high prevalence of quinolone resistance genes, which indicates antibiotic resistance, in the imam reza hospital of mashhad is a major concern. hence, the antibiotics prescription policy should be revised, and infection control measures should be improved. results eighty-six (43%) isolates were ciprofloxacin-resistant. the pct identified 85 (42.5%) of 200 e. coli isolates as esbl...
