Figure. Schematic single nucleotide polymorphism (SNP) tree for Bacillus anthracis. This tree illustrates the relative positions of several sequenced strains of B. anthracis that form the specific sublineages in the A group of B. anthracis and in particular the Western North American lineage (A.BR.WNA, represented by a blue star ). The canonical SNPs and their positions are depicted in red lettering. A branch point (red circle) or node designated A.Br.008/009 originally represented 154 isolates and canSNP analysis places Sverdlovsk 7.RA93.15.15 in this node. The new pagA SNP981 defines a new branch radiating from this node and contains at least 3 other isolates.
