Abstract:

Genomic DNA was extracted from Clonorchis sinensis and Haplorchis taichui, primers for cytochrome c oxidase subunit 1(COX1) gene were designed, respectively, and single and duplex PCR were performed. Single PCR for C. sinensis using three pairs of primers, FC1/RC1 and FC3/RC3 primer pairs generated specific bands of 328 bp and 356 bp, respectively, while no band was produced when using the FC2/RC2 primer pair. Similarly, single PCR using FH1/RH1 and FH2/RH2 primer pairs for H. taichui produced specific bands of 200 bp and 190 bp, respectively. Furthermore, duplex PCR combining the FC1/RC1 primer pair with FH1/RH1 or FH2/RH2 primer pair resulted in specific bands for both C. sinensis and H. taichui, with no cross-species reaction.

Key words: Clonorchis sinensis, Haplorchis taichui, Cytochrome c oxidase subunit 1 gene, Duplex PCR
