In different areas of the world, strains of Echinococcus granulosus have been described which appear to vary in their infectivity, and laboratory primates have been used as indicators of their infectivity to man. This phenomenon was evaluated in Kenya for hydatid material of human, camel, cattle, sheep and goat origin. Viable eggs, produced by experimental infections in dogs with larval material from all the above intermediate hosts, were fed separately to four baboons (Papio cynocephalus) in each case. Baboons were autopsied between 373 and 501 days following infection and the liver, lungs, heart, spleen and kidneys were thoroughly inspected. Hydatid cysts were recovered from two baboons in each of the camel, sheep and goat groups, three baboons in the cattle group and none of the baboons in the human group. Fertile cysts were found in the cattle and goat groups and it is suggested that the baboon could be used as an experimental model for this parasite.
在世界不同地区，已发现细粒棘球绦虫的菌株在感染性方面似乎存在差异，实验室灵长类动物已被用作其对人类感染性的指标。在肯尼亚，针对源自人类、骆驼、牛、绵羊和山羊的包虫材料对这一现象进行了评估。通过用来自上述所有中间宿主的幼虫材料对狗进行实验性感染所产生的活卵，分别喂给每组四只狒狒（黄狒狒）。感染后373至501天对狒狒进行解剖，并对肝脏、肺、心脏、脾脏和肾脏进行全面检查。在骆驼、绵羊和山羊组中，每组有两只狒狒发现了包虫囊肿；牛组有三只狒狒发现了包虫囊肿；人类组的狒狒均未发现。在牛组和山羊组中发现了有繁殖能力的囊肿，提示狒狒可作为这种寄生虫的实验模型。
