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 all over the world.
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, [3] and is classified as a neglected tropical disease (NTD). [4] [5] It affects humans, but its main host is ruminants such as cattle and sheep. [4]
Both F. hepatica and F. gigantica and their hybrids infect the liver tissue of a wide variety of mammals, including humans, in a condition known as fascioliasis. F. hepatica measures up to 30 mm by 15 mm, while F. gigantica measures up to 75 mm by 15 mm. [2] Fasciola nyanzae is thought to exclusively infect the common hippopotamus, Hippopotamus ...
The signs and symptoms of helminthiasis depend on a number of factors including: the site of the infestation within the body; the type of worm involved; the number of worms and their volume; the type of damage the infesting worms cause; and, the immunological response of the body. Where the burden of parasites in the body is light, there may be ...
Fasciolopsis buski is a large, dorsoventrally flattened fluke characterized by a blunt anterior end, undulating, unbranched ceca (sac-like cavities with single openings), tandem dendritic testes, branched ovaries, and ventral suckers to attach itself to the host.
Fasciolidae is a family of trematodes and includes several parasites involved in the veterinary and medical sciences, which cause the disease Fasciolosis.Fasciolidae is divided into five genera by Olson et al. 2003.
Fascioliasis, a parasitic infection of liver caused by a liver fluke of the genus Fasciola, mostly Fasciola hepatica. [5] Hepatitis, inflammation of the liver, is caused by various viruses (viral hepatitis) also by some liver toxins (e.g. alcoholic hepatitis), autoimmunity (autoimmune hepatitis) or hereditary conditions.

Fasciola hepatica, a species of liver flukes, has a higher incidence rate in children and females, with more cases of lung fluke and intestinal trematodiases in children. [5] Cases of liver and lung fluke trematodiasis are frequent due to the length of time the trematode can live in host organisms, and increased chances of reinfection.
