Phylogenetic analysis of the mcr-1-harbouring S. Typhimurium isolates obtained in this study. From left to right: (1) Maximum likelihood (ML) tree of mcr-1-harbouring S. Typhimurium isolates. The font colour of the labels in the tree represents the replicon sequence type of the mcr-1-harbouring plasmids (blue: IncI2, red: IncHI2, green: IncX4); (2) The sampling dates of the outpatients; (3) The length of the mcr-1-harbouring plasmids; (4) A heatmap of the antimicrobial resistance genes on the mcr-1-harbouring plasmids. The yellowish shade indicates close genomic clonal clusters. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
