Notes on animal diseases

Abstract

The more important parasitic worms belong to three phyla, the flatworms (Platyhelminthes), round-worms (Nemathelminthes) and ringed worms (Annelida). The parasitic flatworms are the flukes (class Trematoda) and the tapeworms (class Cestoda). The parasitic round-worms of domestic animals in Kenya are all members of the class Nematoda and the only parasitic annelids are the leeches (class Hirudinea). Before detailing the more important parasitic worms of stock, a few brief notes on the causes and diagnosis of worm infestations will enable the reader to obtain a better appreciation of the problem and will avoid much repetition.
