What is trematode and Cestode?

INTRODUCTION. Cestodes (tapeworms) and Trematodes (flukes) are two Classes of the Phylum Platyhelminthes. Tapeworms live in the intestines of vertebrates and their larval forms occur in the flesh of animals on which these vertebrates feed.

What is the meaning of trematodes?

Definition of trematode : any of a class (Trematoda) of parasitic usually hermaphroditic flatworms including the flukes.

What is difference between Cestode and trematode?

Cestodes are tape-like and segmented in shape, have a head with suckers and possibly hooks, and lack a digestive tract. Trematodes are leaf-like and unsegmented, lack hooks entirely, and have an incomplete digestive tract. Generally, cestodes require two hosts and trematodes need three to complete their life cycles.

What is nematode and trematode?

The trematodes or flatworms are flat, leaf-shaped and unsegmented. They are hermaphroditic, meaning they have the reproductive organs associated with both males and females. Nematodes are cylindrical and have lips, teeth and dentary plates. The worms are either male or female.

What is trematode morphology?

While different trematode species may possess features that are absent in others, they share a number of morphological features. For instance, like most platyhelminths, trematodes are defined by dorsoventrally flattened (unsegmented) bodies that are bilaterally symmetrical. They have a leaf-shaped body.

Is trematode the same as nematode?

Trematodes are hermaphroditic and utilize oral suckers, ventral suckers or acetabulum for attachment organs. Nematodes are characterized by a cylindrical body shape and do indeed have a body cavity. Its body covering is a cuticle and the digestive tube ends in the anus.

What is Parasitology trematodes?

Trematodes, also called flukes, cause various clinical infections in humans. The parasites are so named because of their conspicuous suckers, the organs of attachment (trematos means “pierced with holes”). All the flukes that cause infections in humans belong to the group of digenetic trematodes.
