outbreak of infection caused by enterobacter cloacae producing the novel veb-3 beta-lactamase in china.over a 4-month period from november 2002 to february 2003, 27 ceftazidime-resistant or cefotaxime-resistant nonrepetitive enterobacter cloacae isolates were collected from 27 patients hospitalized at huashan hospital, shanghai, people's republic of china. the etest did not detect extended-spectrum beta-lactamases (esbls) in those 27 isolates; however, screening by the nccls esbl disk test and confirmatory tests detected esbls in 4 of 27 isolates and pcr detected esbls in 23 of 27 isolates. the m ...200515695687
[detection of extended-spectrum beta-lactamases and drug sensitivity test in clinical isolates of the family enterobacteriaceae in shanghai].to investigate extended-spectrum beta-lactamases (esbls) production in clinical isolates of the family enterobacteriaceae in shanghai, and compare the resistant rates of esbls-producing strains and non-esbls-producing strains to 11 antibiotics.200011778509
plasmid-mediated 16s rrna methylases in aminoglycoside-resistant enterobacteriaceae isolates in shanghai, china.high-level resistance to aminoglycosides produced by 16s rrna methylases in enterobacteriaceae isolates was investigated. the prevalences of arma in escherichia coli, klebsiella pneumoniae, and enterobacter cloacae were 0.6%, 3.0%, and 10%, respectively. rmtb was more prevalent than arma. pulsed-field gel electrophoresis patterns indicated that arma and rmtb have spread horizontally and clonally.200918955532
