Figure 1

Evolution and variation of SC11 inferred from core genome SNPs during rapid transmission and divergence of vancomycin-resistant Enterococcus faecium ST80, China. Graphs shows reconstructed tree from core genome SNPs (left) among all SC11 isolates (n = 235) using strain SZYSC_GYSVRE003 (GenBank accession no. GCA_037475005.1) as reference. Hospital sources of isolates from Shenzhen ST80 and its variant, and SC11-pop II isolates are indicated (1, 2, and 3) next to the tree. The heatmap (right) shows pairwise SNP distance matrix indicating diversity of SC11 lineage presented in the form of symmetry in the bottom left and top right. Cells in the heatmap are colored to show SNP distance in a graded gradient. Red lines indicate large SNP distances and correspond to SZYSC_23VRE019 in the tree. pop, population; SC, sequence cluster; SNP, single-nucleotide polymorphism; ST, sequence type.
