The metacercariae of Centrocestus formosanus, a minute intestinal trematode of mammals and birds, were detected in the freshwater fish, Puntius brevis, from Vientiane Municipality, Lao PDR. The metacercariae were experimentally fed to mice, and adult flukes were recovered in their small intestines 7 days later. The adult flukes were morphologically characterized by having 32 (rarely 34) circumoral spines arranged in 2 alternative rows, a large bipartite seminal vesicle, an oval-shaped ovary, and an X-shaped excretory bladder. Based on these characters, the adults were identified as Centrocestus formosanus (Nishigori, 1924). The taxonomic significance of C. formosanus, in relation to a closely related species, C. caninus (Leiper, 1913), is briefly discussed. It has been first verified by adult worm recovery that C. formosanus is prevalent in Vientiane areas of Lao PDR, taking the freshwater fish, P. brevis, as a second intermediate host.
在老挝万象市的淡水鱼短须鲃中检测到了台湾棘带吸虫的囊蚴,台湾棘带吸虫是一种寄生于哺乳动物和鸟类肠道的小型吸虫。将囊蚴经口感染小鼠,7天后在小鼠小肠内检获成虫。成虫形态特征为口周有32个(少数为34个)交替排列的棘,分2排,有一个大的二分精囊、一个椭圆形卵巢和一个X形排泄囊。根据这些特征,成虫被鉴定为台湾棘带吸虫(Nishigori,1924)。简要讨论了台湾棘带吸虫与近缘种犬棘带吸虫(Leiper,1913)的分类学意义。首次通过成虫检获证实台湾棘带吸虫在老挝万象地区流行,以淡水鱼短须鲃作为第二中间宿主。
