How do you identify Trematoda?
Diagnosis of trematode infection is commonly accomplished by identification of eggs in feces or urine. The eggs of most species are structurally distinct and the diagnosis can be made by standard light microscopy. With the exception of fascioliasis, the drug of choice for trematode infections is praziquantel.
What is Trematoda in biology?
Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes. They are internal parasites of molluscs and vertebrates. Most trematodes have a complex life cycle with at least two hosts. The primary host, where the flukes sexually reproduce, is a vertebrate.
What is the shape of trematodes?
1 General biology of trematodes. Trematodes are flatworms classified in the phylum Platyhelminthes, class Trematoda, subclass Digenea. In general, trematodes are dorso-ventrally flattened and leaflike in shape.
What is the habitat of Trematoda?
Habitat: The larvae of human blood flukes live in freshwater snails. The adults live in veins in the abdomens of mammals such as rodents, dogs, cattle, baboons, and humans.
Is a tapeworm a Cestode?
Cestodes, or tapeworms, include multiple species of flat worms that can reside in the human gastrointestinal tract. The species that most commonly cause human disease include Taenia saginatum, Taenia solium, Diphyllobothrium latum and Hymenolepis nana.

How does a cestode attach to host tissues?
The adult tapeworm has a scolex (head), a short neck, and a strobila (segmented body) formed of proglottids. Tapeworms anchor themselves to the inside of the intestine of their host using their scolex, which typically has hooks, suckers, or both. They have no mouth, but absorb nutrients directly from the host’s gut.
Which of the following describes a cestode?
Cestodes, commonly called tapeworms, are the taxonomic class of Cestoda, which are parasitic worms. They have a tape-like and segmented body. These animals are hermaphroditic, lack a digestive tract, and do not have a body cavity.
What is a trematode in biology?
Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes . They are internal parasites of molluscs and vertebrates. Most trematodes have a complex life cycle with at least two hosts. The primary host, where the flukes sexually reproduce, is a vertebrate.
How do trematodes stay attached to their host?
These allow trematodes to remain attached to their host. Using the powerful muscular pharynx that makes up the mouth part, trematodes (both the larvae and adult stages) are able to suck food from the host as they remain attached using both the posterior and ventral suckers.
What are the life cycle adaptations of trematodes?
Life cycle adaptations. Trematodes have a large variation of forms throughout their life cycles. Individual trematode parasites life cycles may vary from this list. Trematodes are released from the definitive host as eggs, which have evolved to withstand the harsh environment. Released from the egg is the miracidium.
What are the neuro secretions of the trematodes?
As there is no circulatory system in trematodes so these secretions are delivered by nervous system in the intercellular spaces of the desired region. The nervous system of trematode is comparatively highly secretory. Mostly neurosecretory cells present in the anterior region in ganglia. The neuro secretions of trematodes changes from time to time.
