Recombination rates inferred by ClonalFrame on separate lineages.

All values are the mean of 5 independent runs with their 95% credibility interval (CI) given in brackets.*: STs with admixture were removed from the lineage-specific analysis but were present for the global analysis of all STs. For lineage 2, STs with ambiguous phylogenetic position (ST93, ST94, ST38 and ST39) were also removed.θ: fixed mutation rate based on the Watterson moment estimator θw.ρ: recombination rate.r/m: relative impact of recombination versus mutation in generating genetic diversity.ρ/θ: relative frequency of occurrence of recombination in comparison to point mutation.
