Specific blaCTX-M-8/IncI1 Plasmid Transfer among Genetically Diverse Escherichia coli Isolates between Humans and Chickens.

ABSTRACT: We investigated the genetic backbones of 14 blaCTX-M-8-positive Escherichia coli isolates recovered from human stool samples and chicken meat. All isolates carried IncI1 plasmids with blaCTX-M-8 (blaCTX-M-8/IncI1), and most (9/14) belonged to a specific genetic lineage, namely, plasmid sequence type 113 (pST113). The genetic contexts of the nine blaCTX-M-8/IncI1 pST113 plasmids were similar, regardless of the source. These results suggest the probable local transfer of blaCTX-M-8/IncI1 between humans and chickens with genetically diverse E. coli.
