Eggs ofOpisthorchisspp. are 19-30 袖m long by 10-20 袖m wide and are often indistinguishable from the eggs ofClonorchissinensis. The eggs are operculated and possess prominent opercular 'shoulders' and andabopercular knob. The eggs are embryonated when passed in feces.
Clonorchissinensiseggs are small, ranging in size from 27 to 35 袖m by 11 to 20 袖m. The eggs are oval shaped with a convex operculum, that rests on visible "shoulders," at the smaller end of the egg. At the opposite (larger, abopercular) end, a small knob or hooklike protrusion is often visible. The miracidium is visible inside the egg.

Schistosomamansonieggs are large (114 to 180 袖m long by 45-70 袖m wide) and have a characteristic shape, with a prominent lateral spine near the posterior end. The anterior end is tapered and slightly curved. When the eggs are excreted in stool, they contain a mature miracidium.
Paragonimuswestermanieggs range from 80-120 袖m long by 45-70 袖m 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.

Eggs ofFasciola hepaticaare broadly ellipsoidal, operculated and measure 130-150袖m long by 60-90 袖m wide. The eggs are unembryonated when passed in feces. The eggs ofF. hepaticacan be difficult to distinguish fromFasciolopsisspp., although the abopercular end of the former often has a roughened or irregular area.
The eggs ofSchistosomajaponicumare large and more rounded than other species, measuring 70-100 袖m long by 55-64 袖m wide. The spine onS. japonicumeggs is smaller and less conspicuous than other species. Eggs are shed in stool.
Microfilaria Wuchereriabancrofti
The eggs ofSchistosomahaematobiumare large (110-170 袖m long by 40-70 袖m wide) and bear a conspicuous terminal spine. Eggs contain a mature miracidium when shed in urine.
Eggs ofFasciola hepaticaare broadly ellipsoidal, operculated and measure 130-150袖m long by 60-90 袖m wide. The eggs are unembryonated when passed in feces. The eggs ofF. hepaticacan be difficult to distinguish fromFasciolopsisspp., although the abopercular end of the former often has a roughened or irregular area.
Serkariaschistosoma
Clonorchissinensisadults are flattened and measure approximately 10-25 mm long by 3-5 mm wide. Like other flukes, they are hermaphroditic, with a single ovary situated anterior to two branches testes. Adults reside in the biliary passages of the liver of the definitive host.
Wuchereriabancrofti
Adults ofFasciola hepaticaare large and broadly-flattened, measuring up to 30 mm long and 15 mm wide. The anterior end is cone-shaped, unlike the rounded anterior end ofFasciolopsisbuski. Adults reside in the bile ducts of the liver in the definitive host.

Adults ofOpisthorchisspp. are similar to, but often smaller than,Clonorchissinensis. Adults measure approximately 7 mm long by 1.5 mm wide in the human host (adults are slightly smaller in feline hosts). Adults ofOpisthorchisspp. differ from adults ofClonorchisin the shape of the testes. The distribution of the vitelline glands is also different. Both genera are similar, however, in having a ventral sucker (acetabulum) smaller than the oral sucker. Adults reside in the bile ducts of the definitive host.
