Two pairs of species-specific primers(ST1 and FT2,B1 and B2) for Trypanosoma evansi and Babesia bovis were designed using the ITS sequence(FJ416612) of T.evansi and clavate binain sequences(FJ588013) of B.bovis(Obtained from GenBank),and a double PCR amplification method for the diagnosis of T.evansi and B.bovis infection was developed.The amplification products of 2136 and 360 bp corresponded to the T.evansi and B.bovis,respectively,have been resolved successfully with the lowest detection limit of 4.00 pg...
