Phylogenetic reconstruction of 25 B. microti samples. Bayesian maximum clade credibility phylogeny of complete apicoplast genome sequences (28.7 Kb) from the 25 B microti samples calculated from the posterior distribution of trees generated by Bayesian MCMC coalescent analysis in BEAST [69]. Bayesian coalescent analysis was performed with a substitution rate of 1.2 × 10−8 substitutions per site per year (1.2 % per million years). Branches defining major clades are displayed in different colors, which correspond to the colors in Fig. 1 (b, c). Divergence dates (median estimates and 95 % HPD) are given in parenthesis for major nodes. Posterior probabilities > 0.65 are indicated at each node. The timescale is indicated below the phylogeny. Babesia microti-human derived samples are marked with “*”
