曼氏血吸虫是导致新热带地区人类肠道血吸虫病的血吸虫，在1500年至1800年期间通过非洲奴隶反复输入。这种吸虫及其中间寄主生物螺属蜗牛广泛分布在非洲各地，由于存在一种地方性易感同系物B。glabrata。我们comparedB。glabrata与其他4个新热带物种和3个非洲物种共同使用了20个等位酶位点，发现其在表型和系统发育上更像非洲物种；寄生虫和美国寄主蜗牛显然都是历史上或地质上最近的非洲起源。此外，遗传距离、进化分析和化石数据表明，非洲生物phalaria物种本身可能是在2.3-4.5亿年前的跨大西洋分散之后从新热带地区的创始人进化而来的。对现有模式的解释仍然存在问题，因为很少有非洲蜗牛具有遗传和两者的特征。glabrataand AfricanB。飞虫似乎包括几个隐种。
Schistosoma mansoni, the blood fluke responsible for human intestinal schistosomiasis in the Neotropics, was imported repeatedly with African slaves during the period 1500–1800. This trematode, and its intermediate host snails of the genusBiomphalaria, are widely distributed across Africa and the disease is thought to have quickly become established in South America and the West Indies because of the presence of an endemic susceptible congener,B. glabrata. We comparedB. glabratawith four other Neotropical and three African species ofBiomphalariausing 20 allozyme loci and found that it is phenetically and phylogenetically more like the African species; both parasite and American host snail are apparently of historically or geologically recent African origin. Furthermore, genetic distances, cladistic analyses and fossil data suggest the AfricanBiomphalariaspecies may themselves have evolved from Neotropical founders following an initial trans-Atlantic dispersal in the reverse direction 2.3–4.5 Mya. Interpretation of existing patterns remains problematic as few African snails have been characterized genetically and bothB. glabrataand AfricanB. pfeifferiappear to comprise several cryptic species.
