Hydatid material removed at operation from 97 Turkana was compared for fertility and viability with hydatid material removed from camels, cattle, sheep, and goats. The results showed that the human material was extremely fertile and viable, as was material from the camels, goats, and sheep. Cattle cysts were invariably sterile, and the protoscoleces, when present, were comparatively less viable. The high incidence and fertility of hydatid cysts in the Turkana, together with the lack of burial customs thus allowing dogs to have ready access to infected human corpses, means that the Turkana are potential biological participants in the cyclic transmission of Echinococcus granulosus in this region. This is a unique situation, for elsewhere in the world man is regarded as an accidental host who plays no role in the parasite's life cycle.
对从97名图尔卡纳人身上手术摘除的包虫物质，与从骆驼、牛、羊和山羊身上摘除的包虫物质进行了生育力和活力比较。结果表明，人类的包虫物质具有极高的生育力和活力，骆驼、山羊和绵羊的包虫物质也是如此。牛的包虫囊肿总是不育的，原头蚴即便存在，其活力也相对较低。图尔卡纳人中包虫囊肿的高发病率和生育力，再加上缺乏埋葬习俗，使得狗能够轻易接触到受感染的人类尸体，这意味着图尔卡纳人是该地区细粒棘球绦虫循环传播中的潜在生物学参与者。这是一种独特的情况，因为在世界其他地方，人类被视为偶然宿主，在寄生虫的生命周期中不发挥作用。
