extended spectrum β-lactamase-producing strains of escherichia coli in hospitalized children in isfahan, iran
conclusions our data showed that, the high prevalence of beta-lactamase genes among isolates, and it. our findings may provide useful insights in replace of the appropriate antibiotics and it may also prevents of esbls, mediated resistance problem. results from 145 strains of e. coli, 51(35.2%) and 61(42.1%) isolates were resistance to ceftazidime and cefotaxime, respectively. esbl production w...
متن کاملPrevalence of extended-spectrum β-lactamase-producing Escherichia coli on Bavarian dairy and beef cattle farms.
Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli strains are believed to be widely distributed among humans and animals; however, to date, there are only few studies that support this assumption on a regional or countrywide scale. Therefore, a study was designed to assess the prevalence of ESBL-producing E. coli in dairy cows and beef cattle in the southern part of Bavaria, Germa...
متن کاملCompetitive Exclusion Reduces Transmission and Excretion of Extended-Spectrum-β-Lactamase-Producing Escherichia coli in Broilers.
Extended-spectrum β-lactamases (ESBLs) and plasmid-mediated AmpC β-lactamases (pAmpC) are enzymes able to hydrolyze a large variety of β-lactam antibiotics, including third-generation cephalosporins and monobactams. Broilers and broiler meat products can be highly contaminated with ESBL- and pAmpC-producing Escherichia coli strains, also known as extended-spectrum cephalosporin (ESC)-resistant ...
متن کاملPhylogenetic typing and detection of extended-spectrum β-lactamases in Escherichia coli isolates from broiler chickens in Ahvaz, Iran
This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and 75 heart blood samples from bi...
متن کاملIn vitro interaction between cefepime and amoxicillin-clavulanate against extended-spectrum β-lactamase-producing Escherichia coli.
We read with interest the article by Chopra et al. (1) suggesting that empirical therapy with cefepime for bloodstream infections due to extended-spectrum-lactamase (ESBL)-producing Enterobacteriaceae is associated with excess mortality. The effectiveness of cefepime would be compromised by ESBL production, resulting in higher MICs (2, 3). Several beta-lactamase inhibitors (including clavulanat...
