Fig. 2From: The specificity of Babesia-tick vector interactions: recent advances and pitfalls in molecular and field studiesMolecular phylogenetic analysis of 18S rDNA of selected Babesia spp. (550 base pairs). The evolutionary history was inferred by using the maximum likelihood method and the Kimura two-parameter model. The tree with the highest log likelihood (− 2752,03) is shown. The percentage of trees in which the associated taxa clustered together is shown next to the branches. Initial tree(s) for the heuristic search were obtained automatically by applying neighbour-joining and BioNJ algorithms to a matrix of pairwise distances estimated using the maximum composite likelihood approach, and then selecting the topology with a superior log likelihood value. A discrete γ distribution was used to model evolutionary rate differences among sites [five categories (+ G, parameter = 2,1600)]. This analysis involved 32 nucleotide sequences. There were a total of 458 positions in the final dataset. Evolutionary analyses were conducted in MEGA XBack to article page
