Radial phylogram showing the phylogenetic relationship of S. enterica serovar Typhimurium sequence types (STs). The S. Typhimurium STs (red and yellow circles) are rooted to S. Typhi (blue circle). The length of the connecting line is proportional to the degree of divergence. S. Typhimurium STs from various worldwide locations outside sub-Saharan Africa SSA (red) and NTS STs predominantly from SSA (yellow) are indicated.
