Streptococcus suis Sequence Type 7 Outbreak, Sichuan, China
Figure 2. Population snapshot of Streptococcus suis. The entire S. suis multilocus sequence type database is displayed as a single eBURST diagram. The 6 major sequence type (ST) complexes are each denoted by a number. The patterns of descent within these ST complexes are discussed in the text. Primary founders (dark green) are positioned centrally in the cluster, and subgroup founders are shown in light green, except ST-7, which is shown in orange to emphasize its importance. The area of each circle in the diagram corresponds to the abundance of the isolates of the ST in the input data.
