To understand the susceptibilities of Oncomelania hupensis snails to Schistosoma japonicum miracidia from different hosts.
The Schistosoma japonicum eggs from different hosts, such as rabbits, cattle and mice were collected. These eggs were incubated for miracidia, respectively. Each snail from the same site was exposed to 5 miracidia of Schistosoma japonicum from different hosts. The infected snails were fed in the laboratory for two months. Then all the snails were dissected and observed under the dissecting microscope in order to know the infection rate of snails.
In the experiment group, the infection rates of snails infected with miracidia from rabbits, cattle and mice were 1.42%, 8.67% and 19.87%, respectively, the mortality rates were 29.5%, 13.5% and 24.5%, respectively. However, the infection rates of snails in the control group were 2.63%, 2.02% and 11.66%, respectively, and the mortality rates were 24.0%, 49.5% and 18.5%, respectively.
The susceptibilities of Oncomelania snails to Schistosoma japonicum miracidia from 3 kinds of hosts are significantly different.
了解湖北钉螺对不同宿主日本血吸虫毛蚴的易感性。
收集来自兔、牛和小鼠等不同宿主的日本血吸虫卵。将这些卵分别孵出毛蚴。将来自同一地点的每只钉螺暴露于来自不同宿主的5条日本血吸虫毛蚴。感染的钉螺在实验室饲养两个月。然后解剖所有钉螺并在解剖显微镜下观察,以了解钉螺的感染率。
在实验组中,感染兔、牛和小鼠毛蚴的钉螺感染率分别为1.42%、8.67%和19.87%,死亡率分别为29.5%、13.5%和24.5%。然而,对照组钉螺的感染率分别为2.63%、2.02%和11.66%,死亡率分别为24.0%、49.5%和18.5%。
湖北钉螺对3种宿主日本血吸虫毛蚴的易感性存在显著差异。
