Surg Infect (Larchmt) 7:537-45. 2006..coli isolated from intraabdominal infections is not inconsequential, especially in the Asia/Pacific region. The carbapenems and amikacin were consistently active in vitro against E. coli isolates worldwide, including ESBL-producers...
Acquisition of rectal colonization by vancomycin-resistant Enterococcus among intensive care unit patients treated with piperacillin-tazobactam versus those receiving cefepime-containing antibiotic regimensDavid L Paterson
Royal Brisbane and Women s Hospital, University of Queensland, Brisbane, Australia
Antimicrob Agents Chemother 52:465-9. 2008..Although piperacillin-tazobactam inhibits the establishment of VRE colonization in mice when exposure occurs during treatment, our data suggest that this agent may not prevent the acquisition of VRE in patients...

Multiclonal outbreak of Klebsiella pneumoniae producing extended-spectrum beta-lactamase CTX-M-2 and novel variant CTX-M-59 in a neonatal intensive care unit in BrazilDoroti de Oliveira Garcia
Instituto Adolfo Lutz, Sao Paulo, Brazil
Antimicrob Agents Chemother 52:1790-3. 2008..Of the 10 pulsotypes identified during the outbreak and follow-up periods, nine produced CTX-M-2 or its new variant CTX-M-59 and one produced SHV-5. bla(CTX-M-2/59) genes were located on closely related plasmids that were transferable...
