摘要:

分别提取华支睾吸虫和扇棘单睾吸虫的基因组DNA,针对两种吸虫线粒体细胞色素C氧化酶亚单位1(COX1)基因设计引物,进行单重和双重PCR扩增。用针对华支睾吸虫的3对引物进行单重PCR扩增,FC1/RC1和FC3/RC3引物分别扩增出328 bp和356 bp的特异性目的条带,而FC2/RC2引物未扩增出任何条带;用针对扇棘单睾吸虫的FH1/RH1和FH2/RH2引物进行单重PCR扩增,分别扩增出200 bp和190 bp的特异性目的条带。用华支睾吸虫FC1/RC1引物,结合扇棘单睾吸虫的FH1/RH1和FH2/RH2引物,分别进行双重PCR扩增,均能扩增出特异性条带,彼此间无干扰。

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
