| 摘 要： | 目的观察异地子代成(新)螺、子代幼螺对日本血吸虫的易感性和存活情况,为血吸虫病监测预警(哨鼠疫水测定)和防治提供科学依据。方法在安徽安庆和江苏南京采集野外成(老)螺,在现场控制条件下自然繁殖,获取子代成(新)螺和幼螺,然后在室内人工感染无锡株日本血吸虫毛蚴(20条/只),并经饲养70d后分别解剖观察其感染情况及生存率。结果安庆和南京同龄成(老)螺的子代成(新)螺和幼螺毛蚴感染率分别为40.63%(91/224)、36.36%(88/242)和18.23%(33/181)、13.85%(27/195),差异均无统计学意义(χ2=0.892 92、1.346 41,P均>0.05);而两地子代成(新)螺与子代幼螺的感染率比较,则差异有统计学意义(χ2=29.568 3,P<0.01)。两地人工感染后的同龄子代成(新)螺和幼螺生存率分别为74.67%(224/300)、80.67%(242/300)和60.33%(181/300)、65.00%(195/300),差异均无统计学意义(χ2子代成螺=3.113 19、χ2子代幼螺=1.396 28,P均>0.05);但同地子代成(新)螺的存活率与子代幼螺比较差异有统计...

| Abstract: | Objective To observe the susceptibility to Schistosoma japonicum and survival in snails from a distant location and their recent progeny upon manual infection with miracidia of S.japonicum in order to provide a basis for control work and surveillance.Methods Adult snails were collected from the countryside in Anqing and Nanjing and then bred under natural conditions on-site to obtain adult and young snails.Snails were manually infected indoors with miracidia of the Wuxi strain of S.japonicum(20 miracidia pe... |
