A study of the compatibility between Schistosoma intercalatum from Cameroon and its potential vectors Bulinus forskalii from Cameroon, Equatorial Guinea, Ivory Coast and Niger has been carried out. As compatibility test, the snail infection test, completed by an histological study, was used. Snail infection experiments showed that all the populations of B. forskalii we tested are very good potential vectors, with infection rates ranging between 76.5 and 93%. The histological study revealed no defense reaction in the snails, which confirms the perfect compatibility of the B. forskalii populations we studied. In an epidemiological perspective, this study confirms the ever present risk of extension of S. intercalatum parasitosis in Africa.
对来自喀麦隆的间插血吸虫及其在喀麦隆、赤道几内亚、科特迪瓦和尼日尔的潜在病媒福氏小泡螺之间的兼容性进行了一项研究。作为兼容性测试，采用了通过组织学研究完成的蜗牛感染测试。蜗牛感染实验表明，我们测试的所有福氏小泡螺种群都是非常好的潜在病媒，感染率在76.5%至93%之间。组织学研究显示蜗牛没有防御反应，这证实了我们所研究的福氏小泡螺种群具有完美的兼容性。从流行病学角度来看，这项研究证实了非洲间插血吸虫病传播的风险一直存在。
