Subspecies of Oncomelania hupensis were exposed to infection with zoophilic and anthropophilic strains of Schistosoma japonicum. The snails were Philippine O. h. quadrasi from the islands of Bohol, Leyte and Mindanao, O. h. formosana from Changhua and Ilan, and O. h. chiui from Taiwan, O. h. hupensis from China, O. h. nosophora from Japan and O. h. lindoensis from Indonesia. Anthropophilic strains of S. japonicum were from Bohol and Leyte in the Philippines, China, Japan and Indonesia. The zoophilic strains were from Changhua and Ilan, Taiwan. All geographic strains of the parasite developed exceptionally well and produced cercariae in 32-50% of O. h. chiui and 5-43% of the natural snail hosts. Development in other subspecies of snails with geographic strains of the parasite were variable. Only a few O. h. formosana (Changhua) could be infected with the parasites from other geographic areas and only one O. h. quadrasi each from Mindanao became infected with the Bohol and Changhua strains of S. japonicum.
将湖北钉螺的亚种暴露于日本血吸虫的嗜兽性和嗜人性菌株感染之下。这些钉螺包括来自保和岛、莱特岛和棉兰老岛的菲律宾湖北钉螺指名亚种，来自彰化和宜兰的福尔摩沙湖北钉螺，来自台湾的邱氏湖北钉螺，来自中国的湖北钉螺指名亚种，来自日本的有明湖北钉螺以及来自印度尼西亚的林多湖北钉螺。日本血吸虫的嗜人性菌株来自菲律宾的保和岛和莱特岛、中国、日本和印度尼西亚。嗜兽性菌株来自台湾的彰化和宜兰。该寄生虫的所有地理菌株在邱氏湖北钉螺的32%-50%以及天然螺宿主的5%-43%中发育异常良好并产生尾蚴。寄生虫地理菌株在其他钉螺亚种中的发育情况各不相同。只有少数福尔摩沙湖北钉螺（彰化）能够被来自其他地理区域的寄生虫感染，并且棉兰老岛的各一只指名亚种湖北钉螺分别感染了保和岛和彰化的日本血吸虫菌株。
