Figure A1. A) Schematic representation of Staphylococcus aureus clonal complex (CC) 398, generated by eBURST version 3 from the S. aureus multilocus sequence typing database (http://saureus.mlst.net) as of September 2011. Subgroup founders sequence type (ST) 398 (3–35–19–2–20–26–39) and ST291 (3–37–19–2–20–26–32) are double locus variants, despite the depiction of intervening STs ST804 (3–35–19–2–20–26–2) and ST813 (3–37–19–2–20–26–2). Subgroup founders are denoted in larger font. B) spa clonal complex (spa-CC) t571, generated by using the integrated BURP (based upon repeat patterns) algorithm in Ridom StaphType software, version 1.5 (www.ridom.de/staphtype). ST398-associated spa types (t034, t571, t1451) and ST291-associated spa types (t937, t1149, t2313, t2993) described in the article cluster separately as in panel A. Subgroup founders are denoted in larger font.
