The cercarial index defined by Bayssade-Dufour (1977) differs according to the hosts in which Schistosoma mansoni is cycled. This index is close to 1 in African human strains, 1.3 in Carribbean human strains, and 1.6 in strains kept for a number of years in rodents. The first epidemiological and experimental results supported the argument that the transmission of intestinal bilharzia in the mountainous refuge of infection at Grand-Etang, Guadeloup, is maintained exclusively by murine rodents. New epidemiological and experimental data lead us to believe that the black rat of Guadeloup is an inadequate host for S. mansoni, incapable of maintaining the parasite beyond a few cycles.
贝萨德 - 迪富尔（1977年）定义的尾蚴指数因曼氏血吸虫循环所在的宿主不同而有所差异。该指数在非洲人体株系中接近1，在加勒比人体株系中为1.3，在啮齿动物中保存数年的株系中为1.6。最初的流行病学和实验结果支持了这样的观点，即在瓜德罗普岛大埃唐的山区感染避难所中，肠道血吸虫病的传播完全由鼠类啮齿动物维持。新的流行病学和实验数据使我们相信，瓜德罗普岛的黑鼠是曼氏血吸虫不适合的宿主，无法在几个循环之后维持寄生虫的存在。
