Comparison of population metrics across 11 bacterial species. The per-allele recombination to mutation parameter (r/m allele) suggests that B. pseudomallei alleles are between 18 and 30 times more likely to change by recombination rather than mutation. This value is higher than for any other bacterial species yet reported. The low standardized index of association suggests that these populations approach panmixia, and Nei's diversity index suggest that these species are less diverse than many other species.
