The aim of the present study was to explore the population genetic relationships between ascarid of peacock origin and other species by the analysis of the genetic variation.In this research,ascarid was collected from the small intestines of 8 peafowls from Nanlan farm in Yiyang,Hunan province.The partial sequence of mitochondrial cox1(pcox1)and nad1(pnad1)as well as the full sequence of ribosomal ITS gene were amplified by PCR.Then,the Neighbor-Joining phylogenetic trees of peacock-derived ascarid and other ascarid were constructed based on three gene loci to analyze their phylogenetic relati...
