Phylogenetic analyses of mitochondrial and plastid genes. Maximum likelihood phylogenetic trees were constructed with concatenated amino acid sequences of cytochrome oxidase subunit I (cox1), cox3, and cytochrome b genes of the mitochondrial genome (a), and the nucleotide sequences of 16S rRNA (b) and tufa genes (c) of the plastid genome. In all three phylogenetic trees, Babesia naoakii n. sp. formed a sister clade to the common ancestor of B. bigemina and B. ovata
