Phylogenetic tree based on core-gene sequences. Phylogenetic tree generated from the amino acid sequences of the 60 C. difficile core genomes showing the relationship between each strain. The MLST clade and ST data were obtained from the PubMLST analysis. The vertical bar on the right indicates the MLST clade to which each C. difficile strain belongs. Strain CBA7201–CBA7209 isolated from Korean patients with CDI are highlighted in bold
