Description:Under a magnification of 500X, this photomicrograph depicted a single egg of a parasitic trematode, or fluke, from the genus, Opisthorchis.
Eggs of Opisthorchis spp. are 19 - 30µm long by 10 - 20µm wide, and are often indistinguishable from the eggs of Clonorchis sinensis. The eggs are operculated, and possess prominent opercular 'shoulders', as well as an abopercular knob. The eggs are embryonated when passed in feces. Flukes from this genus are responsible for causing the parasitic disease known as opisthorchiasis.
