Abstract
The trematodes infecting man and other mammalian hosts are commonly known as digenetic trematodes; these belong to the phylum Platyhelminthes (flatworms), class Trematoda and subclass Digenea. These are endoparasites of vertebrates and some invertebrates, usually show an oral and a ventral sucker as holdfast organs and have an indirect life cycle. The digenetic trematodes should be differentiated from the other subclasses of Trematoda, namely, Monogenea, usually ectoparasites of fishes and occasionally endoparasites of frogs and turtles, and Aspidogastrea, endoparasites of fishes, turtles and molluscs. These show more complex holdfast organs, which are not in the form of oral and ventral sucker, and usually show a direct life cycle.
