日本滋贺县来自九州加比亚螺（平濑七郎，1927年）（新腹足目：豆螺科）的肝吸虫（后睾吸虫属）尾蚴（复殖目：后睾科）新记录。
New record of the cercariae of liver fluke (Opisthorchis sp.) (Digenea: Opisthorchiidae) from Gabbia kiusiuensis (S. Hirase, 1927) (Caenogastropoda: Bithyniidae) in Shiga prefecture, Japan.

We investigated two species of bithyniid snails, Gabbia kiusiuensis and Parafossarulus manchouricus japonicus, in Shiga Prefecture, Japan, between 2021 and 2024, to evaluate their infections with cercariae of trematodes. A type of parapleurolophocercous cercariae was detected in G. kiusiuensis from a locality near Lake Biwa. 28S rDNA and cox1 sequence analyses revealed that these cercariae probably belong to the genus Opisthorchis Blanchard, 1895. This is the first record of this genus in snails in Japan. Species of Opisthorchis can be pathogenic to mammals and birds, but the actual pathogenicity of the present species remains unknown. The recent spread of G. kiusiuensis in Japan could lead to cases of liver fluke infections.
2021年至2024年期间，我们在日本滋贺县对两种沼螺科蜗牛，即九州沼螺（Gabbia kiusiuensis）和日本满洲拟钉螺（Parafossarulus manchouricus japonicus）进行了调查，以评估它们感染吸虫尾蚴的情况。在琵琶湖附近一个地点的九州沼螺中检测到一种侧尾蚴型尾蚴。28S核糖体DNA（rDNA）和细胞色素氧化酶亚基1（cox1）序列分析表明，这些尾蚴可能属于后睾吸虫属（Opisthorchis Blanchard，1895）。这是该属在日本蜗牛中的首次记录。后睾吸虫属的物种可对哺乳动物和鸟类致病，但目前该物种的实际致病性尚不清楚。九州沼螺最近在日本的扩散可能导致肝吸虫感染病例。
