Escherichia coli: placing resistance to third-generation cephalosporins and fluoroquinolones in Australia and New Zealand into perspective

Evaluation of Antibiotic Resistance to Fluoroquinolones and Third Generation Cephalosporines in Iranian Clinical Isolates of Salmonella spp.

Salmonella enterica serotypes are one of the most important food borne pathogens and significant public health concerns around the world in humans and other animal species. A total of eighty three epidemiologically unrelated clinical isolates of Salmonella enterica serovars were subjected to antimicrobial susceptibility testing. Eleven isolates (13.1%) which were resistant to at least 4 groups ...

National prevalence of resistance to third-generation cephalosporins in Escherichia coli isolates from layer flocks in France.

Resistance of Escherichia coli to third-generation cephalosporin (3GC) in fecal samples representative of French egg production was studied. The susceptibility to cefotaxime of E. coli isolates obtained by culture on nonselective media was determined. Twenty-two nonsusceptible isolates were obtained (7.51%; 95% confidence interval, 4.49 to 10.54%), the majority of which came from young birds. M...

antibiotic resistance to third generation cephalosporins due to ctx-m-type extended-spectrum β-lactamases in clinical isolates of escherichia coli

background: organisms producing ctx-m-β-lactamase are emerging around the world as a source of resistance to oxyiminocephalosporins such as cefotaxime. however, the laboratory detection of these strains is not well defined. the aim of this study was to determine the presence and prevalence of known ctx-m-β-lactamases genes in clinical isolates of  escherichia coli from hospitals of tehran. meth...

Isolation, Identification and in vitro Susceptibility of Avian Escherichia coli to Selected Fluoroquinolones

Resistance to Third-Generation Cephalosporins and Other Antibiotics by Enterobacteriaceae in Western Nigeria

Problem statement: The emergence and spread of resistance to third-generation cephalosporins are threatening to create species resistant to all currently available agents. The most common cause of bacterial resistance to beta-lactam antibiotics is the production of beta-lactamases and many of the 2nd and 3rd-generation penicillins and cephalosporins were specifically designed to resist the hydr...
