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.
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 ...
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]
The life cycle of a typical trematode begins with an egg. Some trematode eggs hatch directly in the environment (water), while others are eaten and hatched within a host, typically a mollusc. The hatchling is called a miracidium, a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like ...
Fasciola hepatica Egg of Dicrocoelium sp. Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. [1] They are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and ...
Microscopic identification of eggs, or more rarely of the adult flukes, in the stool or vomitus is the basis of specific diagnosis. The eggs are indistinguishable from those of the very closely related Fasciola hepatica liver fluke, but that is largely inconsequential since treatment is essentially identical for both.
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.
The life cycle of F. magna is relatively complex and is similar to the development of the related fluke, F. hepatica. A detailed account of the F. magna life cycle was given by Swales (1935), Erhardová-Kotrlá (1971), and reviewed by Pybus (2001). [1] [2] [4] The cercariae of F. magna shed from the snail.
