Figure 1. Global population snapshot of Corynebacterium diphtheriae sequence types. eBURST (http://eburst.mlst.net/) was used to display the C. diphtheriae isolates (n = 616) available in the PubMLST database (http://pubmlst.org/cdiphtheriae/) at the time of analysis (accessed June 13, 2017). Isolates from South Africa (n = 25) are green. The size of each circle is proportional to the number of isolates, and related sequence types are connected by lines. Blue and yellow circles indicate founding and subfounding genotypes, respectively.
