The infection status with Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fishes from Yongjeon-cheon (a branch of Nakdong-gang) located in Cheongsong-gun, Gyeongsangbuk-do, the Republic of Korea (Korea). A total of 750 fishes in 19 species were examined by the artificial digestion method for 2 years (2019 and 2020). CsMc were detected in 378 (51.4%) out of 735 fishes in 14 species (73.7%), and the infection intensity was 666 per fish infected. In 2019, CsMc were found in 172 (68.0%) out of 253 fishes in 10 species, and the infection intensity was 565 per fish infected. In 2020, CsMc were detected in 206 (62.2%) out of 331 fishes in 10 species, and the infection intensity was 751 per fish infected. The other zoonotic trematode, ie. Metagonimus spp., Centrocestus armatus, Echinostoma spp. and Clinostomum complanatum, metacercariae were also detected in fishes from the survey streams, but their endemicities were relatively low. Conclusively, it was first confirmed that CsMc are highly endemic in fishes from Yongjeon-cheon in Cheongsong-gun, Gyeongsangbuk-do, Korea.
在韩国庆尚北道清道郡永泉川（洛东江支流）采集的 19 种 750 尾淡水鱼中，采用人工消化法，对感染华支睾吸虫囊蚴（CsMc）的情况进行了为期 2 年（2019 年和 2020 年）的调查。在 14 种 735 尾鱼中，发现 378 尾（51.4%）感染了 CsMc，感染强度为每尾感染 666 条囊蚴。2019 年，在 10 种 253 尾鱼中发现 172 尾（68.0%）感染了 CsMc，感染强度为每尾感染 565 条囊蚴。2020 年，在 10 种 331 尾鱼中发现 206 尾（62.2%）感染了 CsMc，感染强度为每尾感染 751 条囊蚴。此外，还在调查溪流中的鱼类中检测到其他几种人畜共患的吸虫囊蚴，如并殖吸虫、肝片吸虫、棘口吸虫和口吸盘后尾蚴，但它们的地方性流行程度相对较低。综上所述，首次证实庆尚北道清道郡永泉川的鱼类中 CsMc 高度流行。
