چکیده انگلیسی
Results showed that resistance to extended-spectrum cephalosporins in French pig E. coli isolates is-as in other food animals in France-mainly carried by highly similar blaCTX-M-1 IncI1/ST3 plasmids. These plasmids very often bear other resistance genes such as resistance to sulphonamides (sul2), trimethoprim (dfrA17) and aminoglycosides (aadA5), and occasionally to tetracycline (tet(A)), macrolides (mph(A) and erm genes), phenicols (floR) or streptomycin (strA, strB). Few virulence genes were detected, including colicins, heat-stable enterotoxins, adhesins or temperature-sensitive hemagglutinins. The other cefotaximases detected were blaCTX-M-27 and blaCTX-M-14, the latter being on an IncF plasmid which showed very close identity to a human epidemic plasmid. Importantly, resistance genes for quinolones or polymyxins were never detected on the extended-spectrum cephalosporins resistance plasmids. These results are helpful to evidence the risk of co-selecting cephalosporins -resistance using antibiotics outside this group. They also highlight the occasional presence in pigs of human epidemic plasmids.
