occurrence of qnra-positive clinical isolates in french teaching hospitals during 2002-2005.bacteria harbouring the novel qnra plasmid-mediated mechanism of quinolone resistance have been described in different countries, but the frequency of their occurrence has not been investigated. in total, 1,468 clinical isolates of enterobacteriaceae with quinolone resistance or extended-spectrum beta-lactamase (esbl) phenotypes were collected from eight teaching hospitals in france during 2002-2005 and screened for qnra. overall, 28 isolates (22 enterobacter cloacae, three klebsiella pneumoniae ...200616961639
[implication of extended-spectrum beta-lactamase enterobacteriaceae in nosocomial infections in neonates].the objective of this study was to determine the incidence of extended-spectrum beta-lactamase (esbls) enterobacteriaceae colonization and infection in hospitalized children.201020826324
spread of novel expanded-spectrum beta-lactamases in enterobacteriaceae in a university hospital in the paris area, 2002, 28 non-duplicate enterobacterial isolates producing extended-spectrum beta-lactamases (esbls) were collected from infected patients at the bicêtre hospital in paris, france. escherichia coli was the predominant esbl-positive enterobacterial species, comprising ten (36%) of the isolates. ctx-m enzymes (ctx-m-3, ctx-m-10, ctx-m-14 and ctx-m-15) were produced by 11 (39%) of the isolates (six e. coli, two enterobacter cloacae, one enterobacter aerogenes, one proteus mirabilis and one citrob ...200515966981
