总结和结论
1.
由于脆弱双变形虫和蛲虫同时出现在理论预期的20倍多的附录中，这表明两个物种之间存在某种联系。
2.
蛲虫的切片从双变形虫窝藏阑尾揭示了存在于许多小的，阿米巴样，单核生物，其核非常类似于那些发现在单核和双核D。从福尔马林固定的阑尾腔中分离出脆弱细胞。这些尸体在不知道携带D的病例的蛲虫卵中没有发现。脆弱的。因此，蛲虫似乎是D.脆弱的
3.
D.传播的间接证据介绍了蛲虫卵中的fragilis，但从卵中培养阿米巴的努力尚未成功。
4.
进一步的证据表明，Dientamoeba与导致火鸡黑头的鞭毛虫组织单胞菌有关。这倾向于证实Dobell的假设，即D。fragilis实际上是一种异常的鞭毛虫，而不是真正的阿米巴，目前对它的分类是错误的。
Summary and Conclusions
1.
As Dientamoeba fragilis and Enterobius vermicularis occurred together in 20 times as many appendices as theoretically expected, it indicated some connection between the two species.
2.
Sections of pinworms from a Dientamoeba-harboring appendix revealed the presence in many eggs of small, ameboid, uninucleate organisms, whose nuclei greatly resembled those found in uni- and binucleate D. fragilis from the lumen of formalin-fixed appendices. These bodies were not found in pinworm eggs from cases not known to harbor D. fragilis. Therefore, the pinworm appears to be a vector of D. fragilis.
3.
Indirect evidence of transmission of D. fragilis in pinworm eggs is presented, but efforts to culture the ameba from eggs have not yet been successful.
4.
Further evidence linking Dientamoeba with Histomonas meleagridis, the flagellate which causes blackhead in turkeys, is presented. This tends to confirm Dobell's hypothesis that D. fragilis is actually an aberrant flagellate rather than a true ameba and that its present classification is an error.
