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. The young worms move through the intestinal wall, the abdominal cavity, and the liver tissue, into the bile ducts, where they develop into mature adult flukes that produce eggs. The pathology typically is most pronounced in the bile ducts and liver. Fasciola infection is both treatable and preventable.
As adult Fasciola hepatica lives in the liver and bile ducts of sheep as an endoparasite, it is very well adapted for its parasitic mode of life. In fact, on one hand adult fluke exhibits certain adaptive features and on the other a number of adaptive features may also be . 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, and is classified as a neglected tropical disease (NTD). It affects humans, but its main host is ruminants such as cattle and sheep. The disease progresses through four distinct phases; an initial incubation phase of Specialty: Infectious medicine.
Fasciola hepatica, adult. Courtesy of Dr. Raffaele Roncalli. Fasciola hepatica egg. Courtesy of Dr. Lora Ballweber. Eggs are passed in the feces, and miracidia develop within as little as 9–10 days (at 22°–26°C [71.6°–78.8°F]; little development occurs below 10°C [50°F]). Hatching only occurs in water, and miracidia are short-lived. Objective. To evaluate the effects of lead in the morphology and viability of Fasciola gigantica (F. gigantica) (giant liver fluke) isolated from infected livers of carabaos in vitro using the following concentrations of lead: 0, 100, 150 and 200 mg/L.Cited by: 4.
