初次实验感染日本血吸虫的姬鼠,虫体能发育成熟,并从粪中排出虫卵;感染后11周左右,虫体有自然消失趋向,但再次感染后,虫体仍可发育成熟并从粪中排出虫卵。虫卵孵出的毛蚴能感染钉螺,逸出的尾蚴能再感染姬鼠和小白鼠。由于姬鼠在自然界可被多次感染,因此,它在血吸虫病流行病学上有一定意义。 In the first experiment, Apodemus japonicus infected with Schistosoma japonicum, the larvae developed maturely and excreted eggs from the excrement. After 11 weeks of infection, the larvae tended to disappear spontaneously. However, after the infection, the parasites could still mature and develop from the excrement In the discharge of eggs. Eggs hatched miracidia can infect snails, escaped cercariae can be infected with Apodemus and mice again. As Apodemus can be infected many times in nature, it has some significance in the epidemiology of schistosomiasis.
