What are Digenetic flukes?

What is the difference between Monogenetic and Digenetic flukes?
– Additionally, if an organism can complete its life cycle inside a single host it is termed as monogenetic while if an organism utilises two host organisms for completing its life cycle it is termed as digenetic organisms. – Liver flukes spend their life cycle utilising two hosts.
What is the most common 1st intermediate host among Digenetic trematodes?
snail
As many as three intermediate hosts and a single definitive host may be required to complete a digenetic trematode life cycle. The first intermediate host is typically a gastropod (snail). The definitive host is always a vertebrate.
What is Digenetic nematode parasite?
Digenic trematodes are unsegmented, leaf-shaped worms that are flattened dorsoventrally. They bear 2 suckers, one surrounding the mouth (oral sucker) and another on the ventral surface of the body (ventral sucker). These serve as the organs of attachment. The sexes of the parasites are not separate (monoecious).
What is Digenetic?
Definition of digenetic : of or relating to a subclass (Digenea) of trematode worms in which sexual reproduction as an internal parasite of a vertebrate alternates with asexual reproduction in a mollusk.
Which of the following is Digenetic parasite?
Solution : The parasites which complete their life cycle in the body of two hosts are called digenetic parasites. Example : Liver fluke (Fasciola hepatica) completes its life cycle in sheep and snail.
What is Monogenetic and Digenetic parasite?
Monogenetic parasites are the parasites that complete their life cycles in one host only. Digenetic parasites are those that need more than one host (usually two) to complete their life cycles.
Is fasciola a Monogenetic or Digenetic trematode?
The adult form of the fasciola hepatica is seen in the vertebrate host and larval stages are seen in the invertebrate host and it mainly lives in the bile duct of the sheep. That is the reason why the fasciola hepatica is called a digenetic endoparasite.
