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).
The disease caused by the fluke is called fasciolosis or fascioliasis, which is a type of helminthiasis and has been classified as a neglected tropical disease. [2] Fasciolosis is currently classified as a plant/food-borne trematode infection, often acquired through eating the parasite's metacercariae encysted on plants. [ 3 ]
One prevention method is to kill off the snail hosts in a water body using molluscicides. [18] Another method is treating entire communities that are at risk for contracting fascioliasis with triclabendazole. [12] This is a time efficient method in impoverished rural communities, as it does not require testing the entire community for ...
The infection is commonly called fasciolosis. The prevalence of F. gigantica often overlaps with that of Fasciola hepatica , and the two species are so closely related in terms of genetics , behaviour, and morphological and anatomical structures that distinguishing them is notoriously difficult.

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.
Fasciolosis of sheep, goats and cattle, is the major cause of economic losses in dairy and meat industry. [5] Fasciolosis of humans produces clinical symptoms such as fever, nausea, swollen liver, extreme abdominal pain, jaundice and anemia. [6] Clonorchiasis and opisthorchiasis (due to Opisthorchis viverrini) are particularly dangerous. They ...
Adult flukes occur in the liver of the definitive host and feed on blood. Mature flukes measure 4 to 10 centimetres (1 + 1 ⁄ 2 to 4 in) in length × 2 to 3.5 centimetres (3 ⁄ 4 to 1 + 3 ⁄ 8 in) in width, and have an oval dorso-ventrally flattened body with oral and ventral sucker. The flukes are reddish-brown in colour and are covered by ...
