Phylogenetic analysis of Shigella sonnei genomes sequenced in this study and publicly available S. sonnei genomes. Maximum likelihood phylogenetic tree (midpoint rooted) based on core genome SNPs showing phylogenetic relationships among 470 S. sonnei strains. The Latin-American (LA) lineages are based in the study by Baker et al. (2017). The country of origin of LA strains is shown in the colored ring, according to the legend. The global reference strains in the tree do not have country labels. The presence of antimicrobial resistance determinants of Chilean S. sonnei strains sequenced in this study is shown in the outer tracks, according to the legend. The tree was edited using iTOL (Letunic and Bork, 2016).
