Under a magnification of 500X, this unstained photomicrograph revealed some of the ultrastructural details exhibited by an ovum (egg) of a Capillaria philippinensis nematodal parasite. This was a wet mounted specimen. C. philippinensis eggs are 35µm - 45µm in length, by 20µm - 25µm in width. They have two inconspicuous polar prominences, and a striated shell. Eggs are unembryonated when passed in feces.
