Molecular characterization of nosocomial CTX-M type beta-lactamase producing Enterobacteriaceae from a tertiary care hospital in south India.
CTX-M group of extended spectrum beta lactamases (ESBLs) represents a rapidly emerging problem in many countries. The prevalence of nosocomial bla CTX-M-1 producing Enterobacteriaceae strains has not been reported earlier in Indian hospitals. This study describes molecular subtyping of nosocomial bla CTX-M producing strains of Enterobacteriaceae . Polymerase chain reaction with primers specific...
متن کاملPrevalence and Molecular Characterization of Plasmid-mediated Extended-Spectrum β-Lactamase Genes (balaTEM, blaCTX and blASHV) Among Urinary Escherichia coli Clinical Isolates in Mashhad, Iran
Objective(s) 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 ...
متن کاملPrevalence and characterization of extended-spectrum β-lactamase-producing Enterobacteriaceae in food-producing animals in Northern Italy.
The aim of this study was to assess the production of extended spectrum beta-lactamases (ESBL) in 56 strains of Enterobacteriaceae, obtained from 100 rectal swabs of farm animals, and to evaluate the horizontal transfer ca- pacity of the genetic determinants of resistance. The ESBL-positive strains were confirmed by phenotypic testing, confirmed by PCR and DNA sequence analysis. The localizatio...
متن کاملPrevalence of Multiple Drug Resistant Clinical Isolates of Extended-Spectrum Beta-Lactamase Producing Enterobacteriaceae in Southeast Iran
Background: Multidrug resistance and production of extended spectrum β-lactamases (ESBLs) by enteric gram-negative rods in hospitals and community continue to be worsened. We aimed to characterize the multidrug resistance and determine the prevalence of ESBL production by clinical isolates of Enterobacteriaceae in southeast Iran. Methods: Gram-negative bacteria isolated from clinical samples of...
متن کاملGenetic properties of blaCTX-M and blaPER β-lactamase genes in clinical isolates of Enterobacteriaceae by polymerase chain reaction
Objective(s):blaCTX-Mand blaPER are two genes that encode class A extended-spectrum β-lactamases (ESBLs) and can be responsible for therapeutic problems. This study was carried out to evaluate the molecular properties of these genes in clinical isolates of Enterobacteriaceae by polymerase chain reaction (PCR), restriction digestion and sequencing. Materials and Methods: During six months, start...
