What is the phylum of Fasciola hepatica?
FlatwormFasciola hepatica / PhylumThe flatworms, flat worms, Platyhelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Wikipedia
Is Fasciola a Platyhelminthes?
Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum Platyhelminthes. It infects the livers of various mammals, including humans, and is transmitted by sheep and cattle to humans the world over.
What is the classification of Fasciola?
FlukesFasciola / ClassTrematoda 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. Wikipedia
What are the characteristics of Fasciola hepatica?
Adults of Fasciola hepatica are large and broadly-flattened, measuring up to 30 mm long and 15 mm wide. The anterior end is cone-shaped, unlike the rounded anterior end of Fasciolopsis buski. Adults reside in the bile ducts of the liver in the definitive host.
What are the larval stages of Fasciola?
- Miracidium Larva: It is the first larval stage in the life cycle of Fasciola hepatica.
- Sporocyst Larva: Miracidium loses its apical gland, penetration grand, brain and eyespots and changes into a saclike sporocyst larva.
- Redia Larva:
- Cercaria Larva:
How many larval stages are in Fasciola?
Parasite morphology: These flatworms form seven different developmental stages: eggs, miracidia, sporocysts, rediae, cercariae, metacercariae, and adult flukes.
Is Fasciola a zoonotic?
Etiology. Fascioliasis is a parasitic zoonotic infection caused by two trematode species: Fasciola hepatica and F. gigantica. Both are leaf-shaped and large enough to be visible to the naked eye.
Which is the infective stage to primary host of Fasciola?
The adult flukes reside in the large biliary ducts of the mammalian host. By this life cycle, it is known that the infective stage of Fasciola hepatica is metacercaria.
What is the order of Fasciola gigantica?
EchinostomidaFasciola gigantica / Order
What are the differences between Fasciola hepatica and Fasciola gigantica?
gigantica are longer but narrower, with a smaller shoulder, more anterior testes, larger ventral sucker and shorter cephalic cone compared to F. hepatica. In addition, the branching pattern of the caeca, ovary and testes is different in both species. The eggs are similar in shape, but are slightly larger in F.
Which larval stage of Fasciola does not produces several Lavi?
Correct answer:(d) Cercaria.
