Article Synopsis
- Serum samples were collected from 2,643 suspected cases of paragonimiasis in Ningbo City between 2000-2007 to assess infection rates among humans and various animal hosts.
- Out of the samples tested, 417 showed positive antibodies, resulting in an overall seropositivity rate of 15.8%, with residents in endemic areas having a much lower rate between 2.8% to 3.2%.
- Infection rates in the identified intermediate hosts revealed a very low rate in snails (0.05%), a high rate in crabs (31.1%), and a moderate rate in animal reservoirs (11.9%), indicating that natural habitats for the parasite still exist in the region.
Genetic diversity of Z:ZCLA Mongolian gerbils, wild Mongolian gerbils and 3 inbred M. gerbil strains was evaluated with 17 microsatellite loci. The genetic variabilities within and between populations were estimated.

Objective: To identify Paragonimus harinasutai from Ninghai, Zhejiang Province, China.
Methods: Metacercariae 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).
This study presents the first microsatellite investigation into the level of genetic variation among Schistosoma japonicum from different geographical origins. S. japonicum isolates were obtained from seven endemic provinces across mainland China: Zhejiang (Jiashan County), Anhui (Guichi County), Jiangxi (Yongxiu County), Hubei (Wuhan County), Hunan (Yueyang area), Sichuan 1 (Maoshan County), Sichuan 2 (Tianquan County), Yunnan (Dali County), and also one province in the Philippines (Sorsogon).
