A part of the cox1 (pcox1), rrnL (prrnL), nad1 and nad4 genes (pnad1 and pnad4) were amplified separately from individual nematodes by PCR and sequenced. The length of the sequences of pcox1, prrnL, pnad1 and pnad4 was 441 bp, 450 bp, 526 bp and 914 bp for C. ovina, and 441 bp, 451 bp, 517 bp and 810 bp for C. erschowi, respectively. The intra-specific sequence variations within C. ovina were 0.2-2.9% for pcox1, 0-0.9% for prrnL, 0.6-2.3% for pnad1, and 0.4-2.0% for pnad4, and were 0.5-1.6% for pcox1, 0-1.1% for prrnL, 0.2-1.7% for pnad1, and 0.4-1.1% for pnad4 within C. erschowi. Whereas, the inter-specific sequence differences between the two species were obviously higher, being 11.6-12.9% for pcox1, 9.8-11.1% for prrnL, 14.4-15.9% for pnad1, and 16.4-17.7% for pnad4.

In this study, 23 heteroplasmic individuals were detected in 430 Chinese local horses. Both site and length heteroplasmy were identified in horse Cytb, especially in Xinihe and Ujumqin breeds.
