Fig. 1From: Extensive genome analysis of Coxiella burnetii reveals limited evolution within genomic groupsParSNP tree of 76 C. burnetii isolates overlaid with associated metadata on source of isolation. The same SNP-based tree as seen in Additional file 5: Figure S1, is presented in a radial form; metadata is colour coded according to the legend shown next to the figure. The tree was rooted along the branch leading to GG IV (see Methods). The nine UK genomes are highlighted in bold in the FigureBack to article page
