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.
How can you distinguish between Fasciola hepatica and Fasciolopsis Buski?
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 does Fasciola gigantica cause?
Fascioliasis is a parasitic infection typically caused by Fasciola hepatica, which is also known as “the common liver fluke” or “the sheep liver fluke.” A related parasite, Fasciola gigantica, also can infect people.
What is the infective stage of Fasciola gigantica?
Lifecycle. The lifecycle of F. gigantica is: Eggs (transported with feces) → egg hatch → miracidium → miracidium infect snail intermediate host → (parthenogenesis in 24 hours) sporocyst → redia → daughter redia → cercaria → (gets outside the snail) → metacercaria → infection of the host → adult stage produces eggs.
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.
Is Fasciola hepatica Monoecious or dioecious?
F. hepatica adult flukes are hermaphrodite; each contains both male and female reproductive organs.
How do I know if I have Fasciola hepatica?
The standard way to be sure a person is infected with Fasciola is by seeing the parasite. This is usually done by finding Fasciola eggs in stool (fecal) specimens examined under a microscope. More than one specimen may need to be examined to find the parasite.
What is the causative agent of Fasciola hepatica?
Fasciolosis is a parasitic worm infection caused by the common liver fluke Fasciola hepatica as well as by Fasciola gigantica. The disease is a plant-borne trematode zoonosis, and is classified as a neglected tropical disease (NTD)….

Which is the infective form of Fasciola hepatica for the intermediate host?
Diseases of the Liver Lymnaeid mud snails are intermediate hosts and release the infective form, the metacercaria, onto herbage. Hepatic fasciolosis is mainly of economic importance in sheep or cattle, but other species may provide a reservoir of infection.
How does Fasciola hepatica reproduce?
Liver flukes reproduce both sexually and asexually. Adults are hermaphroditic, capable of both cross- and self-fertilization. The larvae stage known as sporocyst reproduces asexually with its offspring developing into rediae, which also multiply asexually. Adults live in the bile ducts of their mammalian host.
What is the habitat of Fasciola hepatica?
Fasciola hepatica has two stages of growing in its life cycle: the sexual stage in its adult form and the asexual in the larval or intermediate stages (Figure 3). The normal habitat of the parasite is biliary ducts and gall bladder of the definite host.
