Ultrastructural studies conducted to elucidate and compare the microanatomy of the South American (simuliid-transmitted) and the Caribbean (culicoid-transmitted) microfilariae of Mansonella ozzardi revealed that these microfilariae are essentially identical. The only difference detected was the larger central body of the Colombian microfilariae. Although the microanatomy of M. ozzardi microfilaria is essentially the same as that of other microfilariae, some of the subtle differences noted between M. ozzardi and other microfilariae include: amphids of unequal lengths, a large nucleus located approximately 30 microns from the anterior end, and an esophagus which appears to be less developed than that of Loa loa and Brugia spp. The microfilaria has a small cephalic hook, intracellular bacteriae in the hypodermal cells, and crystalloid inclusions which are most prominent in the R-1 cell and are also present in the hypodermal and esophageal cells. These crystalloids appear to be unique to M. ozzardi microfilariae.
为阐明并比较奥氏曼森线虫的南美（蚋传播）和加勒比（蠓传播）微丝蚴的微观解剖结构而进行的超微结构研究表明，这些微丝蚴基本相同。检测到的唯一差异是哥伦比亚微丝蚴的中央体较大。虽然奥氏曼森线虫微丝蚴的微观解剖结构与其他微丝蚴基本相同，但奥氏曼森线虫与其他微丝蚴之间注意到的一些细微差异包括：两性感器长度不等、一个大细胞核位于前端约30微米处、以及一个似乎比罗阿丝虫和布鲁线虫属的食管发育程度更低的食管。微丝蚴有一个小的头部钩、皮下细胞内的细胞内细菌，以及晶体包涵体，这些在R-1细胞中最为突出，也存在于皮下和食管细胞中。这些晶体似乎是奥氏曼森线虫微丝蚴所特有的。
