[Taxonomic status in DNA sequences of five species of genus Paragonimus].
OBJECTIVE
To analyze the taxonomic status of Paragonimus hokuoensis, P. paishuihoensis, P. menglaensis, P. bangkokensis and P. xiangshanensis in Genus Paragonimus Braun, 1899.


METHODS
DNA sequences were obtained from the ITS2 and CO I genes and phylogenetic trees were built from these.


RESULTS
There are some DNA sequence differences among P. paishuihoensis, P. menglaensis, P. bangkokensis and P. xiangshanensis, but the differences are small. P. hokuoensis and P. skrjabini are similar in DNA sequence.


CONCLUSIONS
P. paishuihoensis, P. menglaensis, P. bangkokensis and P. xiangshanensis are closer in the genetic relationship. Their taxonomic status lies between P. skrjabini and P. westermani. The genetic relationship between P. hokuoensis and P. skrjabini is very close.
