The ITS sequences were amplified from each ascarid sample and the amplicons were cloned into pGEM-T Easy vector,respectively.The inserts were successfully sequenced,and the length of ITS in all samples were 846 bp.Sequence analysis revealed that the isolates contained the seguence of complete ITS-1,5.8 S and ITS-2 rDNA.It was the first time report of the complete sequence of ITS and 5.8S rDNA of ascarid nematodes from Zaocys dhumnades.The results of this study lay down the foundation for further study on molecular ep...
