Examples of Parasite Eggs

23.5.1 Examples of Parasite Eggs What Do You See? In general, the following rules are true (there are also many exceptions!)

Trematode eggs are fairly large and have a “cap” (operculum) on one end of the egg. Liver fluke eggs are slightly smaller, and more of a brownish yellow color than are rumen fluke eggs.

Large Roundworm eggs are fairly round in shape with a thick shell.

Small Roundworm eggs are usually smaller, have a thin shell, and are slightly elongated in shape.

Tapeworm eggs are usually slightly bigger than small roundworm eggs. They are roughly round in shape and have a thick shell. Sometimes several “lines” within the egg itself are seen.
