Neighbor-joining tree of COX1 amino acid sequences of Babesia vulpes n. sp. and other piroplasmid species. Sequences analyzed in the context of this study are designated by bold accession numbers of taxon labels. Clade designations are presented as defined previously [3, 50]. The percentage of replicate trees as determined by 1000 replicates of a bootstrap test are shown next to the branches. A Plasmodium falciparum COX1 sequence has been included as the outgroup. The scale-bar represents the evolutionary distance in the units of the number of amino acid substitutions per site. Gray dots designate Babesia species that infect domestic dogs [51]
