Caption:
Under a magnification of 128X, this photomicrograph revealed some of the ultrastructural morphology exhibited by a single trematode, Paragonimus westermani egg. P. westermani eggs range from 80µm to 120µm long X 45µm to 70µm wide. They are yellow-brown, ovoid or elongate, with a thick shell, and often asymmetrical with one end slightly flattened. At the large end, the operculum is clearly visible. The opposite (abopercular) end is thickened. The eggs are unembryonated when passed in sputum or feces. See PHIL 1534 for an even closer view of this egg.
