The present study investigated the infection status of Paragonimus westermani metacercariae in freshwater crabs (n = 363) and crayfish (n = 31) from October 2007 to October 2008 using the crush method. All of the freshwater crabs, Eriocheir japonicus, were negative for P. westermani metacercariae while 10 (32.3%) of the 31 examined crayfish were positive. The 10 positive crayfish were caught in Haenam, Jeollanam-do, and there were 8-59 (mean 28.4) metacercariae per infected crayfish. These results suggest that P. westermani metacercariae are still transmitted by crayfish enzootically in southern Korea, and that freshwater crabs may transmit metacercariae only on rare occasions.
本研究于2007年10月至2008年10月期间，采用挤压法调查了淡水蟹（n = 363）和小龙虾（n = 31）中卫氏并殖吸虫囊蚴的感染情况。所有日本绒螯蟹均未检测到卫氏并殖吸虫囊蚴，而31只接受检查的小龙虾中有10只（32.3%）呈阳性。这10只阳性小龙虾均捕获于全罗南道海南郡，每只受感染的小龙虾体内有8 - 59只（平均28.4只）囊蚴。这些结果表明，在韩国南部，卫氏并殖吸虫囊蚴仍可通过小龙虾在动物群体中传播，而淡水蟹可能仅在极少数情况下传播囊蚴。
