Phylogenetic analyses of reconstructed plasmids carrying blaCTX–M–55 and blaCTX–M–27. (A,B) Neighbor-joining trees of plasmids harboring blaCTX–M–55 and blaCTX–M–27, respectively. The branch lengths are indicated in blue color and the bootstrap values in red. Although plasmids from pigs and farmers are present in the same clades, in panel A of blaCTX–M–55, the plasmids are not of the same replicon types (Supplementary Table S1).
