摘要： Two porcine Escherichia coli isolates harbored the cfr gene on conjugative plasmids of 38,405 bp (pGXEC6) and 41,646 bp (pGXEC3). In these two plasmids, the cfr gene was located within a 4,612-bp region containing a tnpA-IS26-cfr-IS26-Delta hyp element. Plasmid pGXEC3 was almost identical to pGXEC6 except for a 3,235-bp ISEcp1-bla(CTX-M-14b) insertion. The colocation of the multiresistance cfr gene with an extended-spectrum-beta-lactamase gene on a conjugative plasmid may support the dissemination of these genes by coselection.
