Clonal complexes are named in accordance with the clonal complex founder that corresponds to the SNP profile. STs are allocated to clonal complexes on the basis of eBURST default settings (5). The SNP profiles are indicated in the order arcC210, tpi241, tpi243, arcC162, gmk318, pta294, tpi36, pta383. Clonal complex 509 is better known as clonal complex 12, but eBURST analysis indicates that CC509 is the founder. “93” indicates that the isolates have been confirmed as ST-93 by interrogation of aroE252. “CC1 outliers” indicates that the SNP profile corresponds to a small number of outliers in clonal complex 1. “None” indicates that the profile does not correspond to a dominant clonal complex. “Not analyzed” means that the profiles do not match any ST included in the eBURST analysis (but they do match STs in the database). Complete information regarding the relationship between SNP profiles and STs is available at http://www.ihbi.qut.edu.au/research/cells_tissue/phil_giffard/.
