These features grew our interest to design species-specific primers targeting ND5 gene for pig and monkey, ATPase 6 for dog and rat, and cytochrome b for cat species. The whole genome sequences of pig (AF034253.1), monkey
(FJ906803.1), dog (NC_002008.4), rat (NC_012374.1) and cat (NC_001700.1), were retrieved form NCBI database (http://www.ncbi.nlm.nih.gov/)
