Specific blaCTX-M-8/IncI1 Plasmid Transfer among Genetically Diverse Escherichia coli across Humans and Chickens [PublishAheadOfPrint]

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