Detection of Extended-Spectrum-β-Lactamase-Positive Escherichia coli in Bile Isolates from Two Dogs with Bacterial Cholangiohepatitis

摘要

This is the first report of Escherichia coli isolates producing CTX-M-15, the predominant type of extended-spectrum β-lactamase (ESBL) associated with clinical disease in humans in the United Kingdom, in a United Kingdom pet dog. This report also describes the first isolation of CTX-M/Tem ESBL-positive E. coli from bile in dogs with hepatobiliary disease.
