Abstract

High prevalence of extended-spectrum-cephalosporin-resistant Enterobacteriaceae in poultry meat in Switzerland: emergence of CMY-2- and VEB-6-possessing Proteus mirabilis.

Abstract

A study was conduced to explore the prevalence of extended-spectrum-β-lactamase (ESBL)- and plasmid-mediated-AmpC (pAmpC)-possessing Enterobacteriaceae as contaminants of raw poultry meat retailed in Bern, Switzerland. 20 samples were purchased on various days during November and December 2012 in three grocery stores. Fourteen samples (70%) contained ESC-R E. coli (n=11), ESC-R P. mirabilis (n=2), or both resistant species (n=1). ESC-R E. coli strains found in meat originating from Switzerland possessed blaCTX-M-1 and blaCMY-2, whereas those detected in meat imported from other countries harboured blaSHV-12, blaTEM-52, or blaCMY-2. This is the first report of blaVEB-possessing P. mirabilis in a non-human clinical setting and the first description of ESBL- and pAmpC-positive P. mirabilis strains in the food chain.
