Phylogeography of the WNA Bacillus anthracis clone.
The evolutionary tree of the dominant North American B. anthracis lineage (WNA) and mapping of isolate locations supports southern dispersal of anthrax in North America after founding by a European or Asian ancestor (TEA). Circles indicate precise GIS coordinates, squares indicate state-level information, and colors indicate phylogenetic grouping.
