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]
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 ...
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.
Fasciola hepatica, Fasciola gigantica: liver, gall bladder stool Fasciola hepatica in Europe, Africa, Australia, the Americas and Oceania; Fasciola gigantica only in Africa and Asia, 2.4 million people infected by both species freshwater snails Fasciolopsiasis – intestinal fluke [10] Fasciolopsis buski: intestines stool or vomitus (microscope)
The results of the new treatment have since been reported in the Lancet medical journal, showing the dramatic and “life-changing improvements” to vision from the gene therapy for all four ...
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.
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.
