Laboratory experiments were carried out to study the susceptibility of snail vectors to Oriental anthropophilic Schistosoma. Oncomelania hupensis hupensis was readily infected with the local strain of Schistosoma japonicum (Chinese strain), and also infected with S. japonicum (Philippines strain). O.h. quadrasi was only susceptible to its S. japonicum (Philippines strain). The Oncomelania races were refractory to S. mekongi, S. japonicum-like species (Malaysian strain). Tricula aperta (beta race) was readily infected with S. mekongi, S. sinensium and S. japonicum-like species from Malaysia, but not S. japonicum. T. bollingi was susceptible to S. sinensium and S. mekongi. Robertsiella kaporensis was only susceptible to the local strain, S. japonicum-like species from Malaysia. Geographical isolation may be the cause of these differences in compatibility between the snail vectors and the schistosome parasites.
进行了实验室实验以研究钉螺媒介对嗜人型日本血吸虫的易感性。湖北钉螺指名亚种很容易感染日本血吸虫当地株（中国株），也能感染日本血吸虫（菲律宾株）。微小拟钉螺仅对其日本血吸虫（菲律宾株）易感。这些湖北钉螺种群对湄公血吸虫、类日本血吸虫（马来西亚株）具有抗性。开放拟钉螺（β族）很容易感染湄公血吸虫、中华血吸虫以及来自马来西亚的类日本血吸虫，但对日本血吸虫不易感。玻氏拟钉螺对中华血吸虫和湄公血吸虫易感。卡波罗伯茨螺仅对当地株、来自马来西亚的类日本血吸虫易感。地理隔离可能是这些钉螺媒介与血吸虫寄生虫之间相容性差异的原因。
