An extensively drug-resistant (XDR) Escherichia coli strain 258E was isolated from an anal swab sample of a chicken farm of Anhui Province in China. Genomic analyses indicated that the strain 258E harbors an incompatibility group N (IncN) plasmid pEC258-3, which co-produces blaCTX-M-3, blaKPC-2, blaTEM-1B, qnrS1, aac(6´)-Ib-cr, dfrA14, arr-3, and aac(6´)-Ib3. Multiple genome arrangement analyses indicated that pEC258-3 is highly homologous with pCRKP-1-KPC discovered in Klebsiella pneumoniae from a patient. Furthermore, conjugation experiments proved that plasmid pEC258-3 can be transferred horizontally and may pose a significant potential threat in animals, community and hospital settings.
