　　The genetic variations in three mitochondrial DNA(mtDNA)regions,namely portion of cytochrome c oxidase subunit 1(pcox1),NADH dehydrogenase subunit 1(pnad1)and cytochrome b(pcytb),were examined for Dicrocoelium dendriticum samples isolated from different origins in Shaanxi province,northwestern China.The intra-specific sequence differences within D.dendriticum samples were 0-0.52%for pcox1,0-0.73%for pnad1,and 0-0.58%for pcytb.Phylogenetic analyses based on combined sequences of three mtDNA showed that all D.dendriticum samples were clustered together in same clade of Paragonimus westermani.But the phylogenetic trees could not revealed geographically genetic relationships of D.dendriticum isolates in this province.These findings will provide basic information for further study of molecular epidemiology and control ofD.dendriticum infection in this province as well as in China.
