Abstract: To study genetic variation of mitochondrial cytochrome c oxidase subunit Ⅲ (cox3) gene of Eimeria acervulina, the cox3 was amplified by polymerase chain reaction (PCR) and 572 bp of partial cox3 (pcox3) was obtained from five strains of E. acervulina. By sequence comparison and comparative analysis with the cox3 gene of some protozoa of Phylum Apicomplexa avalidable in GenBank, the results showed that there was no difference in the nucleotides of the pcox3 sequences obtained from five strains of E. acervulina, and there were distinct differences in the nucleotides compared with other protozoa of Phylum Apicomplexa. The sequence diferences were 51% and 50% compared with Plasmodium and Leucocytozoon respectively, and was less than 50% compared with Theileria. It was the first time that cox3 of E. acervulina was reported. The results of the present study provided a foundation for further studies of population genetics of Eimeria.
