Ectoparasites And Endoparasites
Muhtasari
Not every threat to a farm animal comes from a germ too small to see. Some threats are visible, crawling on the skin, and some hide deep inside the animal's own gut. A West African Dwarf goat rubbing itself raw against a fence post has a problem living on its skin. A sheep that eats well but grows thin and pale has a problem living inside its body. Both are parasites, and this lesson teaches you to tell the two kinds apart.
You will meet the ectoparasites that ride on the outside of the host, ticks, lice, mites, fleas and the tsetse fly, and the endoparasites that live within it, roundworms, tapeworms and liver flukes. You will trace how a roundworm completes its life cycle straight through the pasture, and how a liver fluke cannot complete its own without borrowing the body of a snail first. Finally you will learn exactly what damage each group does to the animal it lives on, the specific facts WAEC rewards with marks.
