a
VNTR markers found in ORFs are shown in italics.
b
vrrB repeats are not all identical, as some contain multiple nucleotide differences. vrrC markers contain a degenerate 9-nucleotide subrepeat structure that results in fractional repeat sizes in some alleles.
c
D is Nei's marker diversity, which is calculated as 1 − Σ(allele frequency)2 and based solely upon the 89 unique B. anthracis genotypes.
