An epidemiological study was performed to know the recent infection status of metacercariae (PwMc) in freshwater crayfish, , from 2 streams in Jeollanam-do, Republic of Korea. Crayfish were collected from creeks in Bogil-do (Island), Wando-gun, and in a creek near Daeheung Temple in Haenam-gun. The infection rate of crayfish with PwMc in Bogil-do was 89.8%, and the metacercarial burden was 37 PwMc per the infected crayfish. Crayfish in a creek near Daeheung Temple were larger and twice heavier than those in Bogil-do. Of them, 96.5% were infected with PwMc. An average of 140 metacercariae was found in the infected crayfish, almost quadruple to those of Bogil-do. There was a strong correlation between the number of PwMc and body weight of the crayfish. These results suggest that metacercariae are still prevalent in crayfish of the 2 regions in Jeollanam-do, Korea.
开展了一项流行病学研究，以了解韩国全罗南道两条溪流中淡水小龙虾体内后尾蚴（PwMc）的近期感染状况。小龙虾采集自宝吉利岛（Bogil-do）、莞岛郡（Wando-gun）的小溪以及海南郡（Haenam-gun）大兴寺附近的一条小溪。宝吉利岛小龙虾的PwMc感染率为89.8%，每只受感染小龙虾的后尾蚴负荷为37个。大兴寺附近小溪中的小龙虾比宝吉利岛的更大，体重是其两倍。其中，96.5%感染了PwMc。在受感染的小龙虾中平均发现140个后尾蚴，几乎是宝吉利岛小龙虾的四倍。PwMc数量与小龙虾体重之间存在很强的相关性。这些结果表明，后尾蚴在韩国全罗南道这两个地区的小龙虾中仍然普遍存在。
