Schematic structure of mitochondrial genomes of Babesia orientalis (KF218819) (a) and three apicomplexan parasites including (b) B. bovis (AB499088), (c) Theileriaparva (Z23263) and (d) Plasmodium falciparum (M76611). Gene names above the bold line are transcribed from left to right, and those below are transcribed from right to left. White boxes indicate protein-coding genes, cox 1 (cytochrome c oxidase I), cox 3 (cytochrome c oxidase III), and cob (cytochrome b). Fragments of LSU (L1 – L6, LA – LG, 1, 2, 3, 10 and 13) and SSU (SA, SB, SD – SF, 4, 8 and 9) rRNA genes are shown by dark and light gray boxes. TIR represents terminal inverted repeats.
