Intercontinental emergence of Escherichia coli clone O25:H4-ST131 producing CTX-M-15.
BACKGROUND Concomitant with the recent emergence of CTX-M-type extended-spectrum beta-lactamases (ESBLs), Escherichia coli has become the enterobacterial species most affected by ESBLs. Multiple locales are encountering CTX-M-positive E. coli, including specifically CTX-M-15. To gain insights into the mechanism underlying this phenomenon, we assessed clonality and diversity of virulence profile...
متن کاملCTX-M-15-producing urinary Escherichia coli O25b-ST131-phylogroup B2 has acquired resistance to fosfomycin.
OBJECTIVES To describe trends in fosfomycin resistance in urinary isolates of Escherichia coli producing extended-spectrum beta-lactamases (ESBLs) in relation to fosfomycin consumption and to characterize representative fosfomycin-resistant isolates. METHODS In 2007-08, an unexpected increase in fosfomycin resistance in ESBL-producing urinary E. coli was observed. Laboratory records were revi...

of immunosuppression. Thus, the most likely explanation is increased exposure to the parasite. Sources of infection for red squirrels are not known; however, oocysts shed in cat feces may contaminate the nuts, fungi, shoots, and berries that constitute the diet of the squirrel. Stray, unspayed cats are common in the Dutch countryside. More than 3 million domestic cats (Felis domesticus) exist i...
متن کاملDifferent Factors Associated with CTX-M-Producing ST131 and Non-ST131 Escherichia coli Clinical Isolates
OBJECTIVES To determine factors associated with CTX-M-producing ST131 Escherichia coli which is the worldwide predominant lineage among CTX-M-producing E. coli isolates. METHODS Consecutive inpatients with a clinical sample positive for CTX-M-producing E. coli and considered as cases in a previous 8-month (2008-2009) case-control study performed in ten university hospitals in the Paris area w...
متن کاملCTX-M-1 and CTX-M-15-producing Escherichia coli in dog faeces from public gardens
BACKGROUND Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli are increasingly reported in dogs. The objective of this study was to provide data on the prevalence of ESBL-producing E. coli in dog faecal deposits in public gardens. RESULTS A total of 209 faecal deposits collected in nine public gardens in Copenhagen, Denmark were screened by selective enrichment followed by pla...
