Abstract: Objective To identify Paragonimus harinasutai from Ninghai, Zhejiang Province, China. Methods Meta-cercariae were collected from the crabs Sinopotamon chekiangenes in Xixi village of Ninghai County for ITS2 sequence analysis, CO1 sequence analysis and endonuclease BsaHI and StuI analysis by PCR-RFLP. Results The fingerprintings of PCR-RFLP were virtually same to the isolate from Thailand (Nakorn-nayok). The ITS2 sequence with 366 bp and CO1 sequence with 390 bp of the metacercariae collected from Ninghai revealed a nucleotide identity 95.6% and 89.5% respectively to the Thai isolate. Conclusion The study confirmed that Paragonimus harinasutai is present in Ninghai, China, with certain variation on molecular biology in comparison to the Thai isolate.
