A phylogenetic tree based on the core genome SNPs of 430 genomic sequences of S. suis clonal complex 1 was constructed using the maximum likelihood method by FastTree v2.1.10 tool and visualized using interactive Tree of Life tool. The whole genome sequence of S suis serotype 1 strains in the current study are highlighted in yellow. * These original serotype 2 strains assigned in BioSample of GenBank were retyped as serotype 14 in this study.
