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 liver parenchyma. In these organs, they ...
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.
Fasciola pass through five phases in their life cycle: egg, miracidium, cercaria, metacercaria, and adult fluke. [2] The eggs are passed in the feces of mammalian hosts and, if they enter freshwater, the eggs hatch into miracidia. Miracidia are free-swimming.
Clonorchis sinensis, the Chinese liver fluke, is a liver fluke belonging to the class Trematoda, phylum Platyhelminthes. It infects fish-eating mammals, including humans. In humans, it infects the common bile duct and gall bladder, feeding on bile. It was discovered by British physician James McConnell at the Medical College Hospital in ...
A parasite called Heterobilharzia americana, a flatworm commonly referred to as liver fluke, was behind the illness of the 11 dogs. The parasite normally makes its home in Texas and in the South.
Much of what is presently known about Dicrocoelium dendriticum is the result of the work of the naturalist Wendell Krull. [2] While D. dendriticum was discovered by Rudolphi in 1819 and D. hospes was discovered by Loos in 1899, the full life cycle was not known until Krull and C.R. Mapes published a series of papers from 1951-1953 detailing their observations and experiments.
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.
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]
