FIG. 1.
Mutational step model showing the genetic relationships between the B. anthracis MLVA GK genotypes found in Turkey and Georgia and belonging to the A3.a genetic cluster, as defined by Keim et al. (14). Each circle represents a different genotype, and the notations on the lines connecting the genotypes indicate the minimal mutational changes needed to convert one genotype to another. The data are data for Georgian isolates characterized in this work and for the Turkish isolates characterized by Keim et al. (14). The dark gray circles indicate genotypes found in Turkey, the open circle indicates a genotype found only in Georgia, and the light gray circles indicate the genotypes found in both the countries.
