Résumé
Resistance to new generation cephalosporins is an important public health problem globally, in terms of economic and social costs, morbidity and mortality. Βeta-lactamase enzymes are mainly responsible for the antibiotic resistance of Gram negative bacteria and extended-spectrum-β-lactamases (ESβLs) are one of the major determinants of resistance against oxymino-cephalosporins in Enterobacteriaceae. Food-producing animals represent one of the sources of antibiotic resistant bacteria, including pigs. Here we analysed the presence of E. coli resistant to III generation cephalosporins isolated from different matrices collected from intensively bred pigs. A total of 498 E. coli were isolated from faeces and carcasses of pigs at slaughterhouse as well as from pork meat and sausages. Among these, 73 were phenotypically confirmed to be ESβL producers. Genetic analysis revealed that all except two harboured at least one of the three selected genes: bla
