Comparative Population Genomics of the Borrelia burgdorferi Species Complex Reveals High Degree of Genetic Isolation among Species and Underscores Benefits and Constraints to Studying Intra-Specific Epidemiological Processes

Relationships between D' and the physical distance between SNPs.
D' values were calculated from pairs of SNPs using the chromosomal sequences of (A) all strains used in this study, (B) all strains of B. burgdorferi s.s., and (C) all strains of B. garinii. Average D' values obtained for all pairs of SNPs separated by less than 2,000 bp (using 50-bp intervals) are shown.
