Laboratory animals and subspecies of Oncomelania hupensis were exposed to experimental infections with a strain of Schistosoma japonicum from the Lindu Valley, Central Sulawesi, Indonesia. All laboratory animals given 50 cercariae were suspecptible to infection with the greatest number of worms being found in mice followed by Wistar rats, Long Evans rats, Mongolian gerbils, wild rats, hamsters and guinea pigs. Rabbits and the Taiwan monkeys given larger numbers of cercariae were also susceptible to infections. Adult worms were found to reach the largest size in the rabbit and Taiwan monkeys but many worms from rats were immature. Eggs from the Taiwan monkey were larger than those from a dog and from mice. Six subspecies or geographic strains of Oncomelania hupensis were exposed to 3 to 5 miracidia of the Indonesia strain of Schistosoma japonicum and only Oncomelania hupensis lindoensis and Oncomelania upensis chiui from Taiwan were susceptibile and produced cercariae while Oncomelania hupesis formosana from Changhua, Ilan and Kaohsium countries of Taiwan as well as Oncomalania hupensis quadrasi from the Philippines were considered refractory to infection.
将实验动物和不同亚种的湖北钉螺暴露于来自印度尼西亚中苏拉威西省林杜山谷的日本血吸虫株的实验感染中。所有接受50只尾蚴的实验动物都易受感染，其中小鼠体内发现的虫体数量最多，其次是Wistar大鼠、Long Evans大鼠、蒙古沙鼠、野生大鼠、仓鼠和豚鼠。给予较多尾蚴的兔子和台湾猕猴也易受感染。发现成虫在兔子和台湾猕猴体内达到最大尺寸，但来自大鼠的许多虫体未成熟。台湾猕猴的虫卵比狗和小鼠的虫卵大。将6个湖北钉螺亚种或地理株暴露于3至5个印度尼西亚日本血吸虫株的毛蚴中，只有来自台湾的林杜湖北钉螺和邱氏湖北钉螺易感并产生尾蚴，而来自台湾彰化、宜兰和高雄县的福尔摩沙湖北钉螺以及来自菲律宾的拟钉螺则被认为对感染具有抗性。
