Fasciola hepatica. Linnaeus, 1758. 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 the world over First phenotypic description of Fasciola hepatica/Fasciola gigantica intermediate forms from the human endemic area of the Nile Delta, Egypt. Fasciola gigantica is the main fasciolid species in Africa; however, F. hepatica and F. gigantica overlap in some countries. Egypt deserves mentioning because of the emerging situation of human fascioliasis. Fascioliasis is a plantborne and zoonotic parasitic disease caused by fasciolid liver flukes. Fasciola hepatica is the only fasciolid species described in the Americas. Human fascioliasis endemic areas are mainly located in high altitude areas of the Americas The two species of trematodes that cause fascioliasis (Fasciola hepatica and Fasciola gigantica) are leaf-shaped worms, large enough to be visible to the naked eye (adult F. hepatica measure 20-30 mm x 13 mm; adult F. gigantica measure 25-75 mm x 12 mm). They cause similar diseases in humans Fascioliasis is an important human disease caused by Fasciola hepatica and F. gigantica, transmitted by freshwater lymnaeid snails and with many livestock species acting as reservoirs (Mas-Coma, 2004). The geographical distribution of both causal agents overlaps in many African and Asian countries (Mas-Coma et al., 2005). Despite the importance to differentiate between the infection by either fasciolid species, due to their distinct epidemiological, pathological and control characteristics.
1. Meaning of Fasciola Hepatica: Liver flukes are typical digenean trematodes and are commonly called flatworms or flukes on account of their flat, leaf-like structure. Fasciola hepatica is the common liver fluke of sheep. It is the first trematode whose life history was described by Thomas in 1883 Liver Fluke (Fasciola Hepatica) Liver fluke (fascioliasis) is caused by the parasite Fasciola Hepatica. Disease can result from the migration of large numbers of immature flukes through the liver, or from the presence of adult flukes in the bile ducts Fascioliasis is a parasitic infection typically caused by Fasciola hepatica, which is also known as the common liver fluke or the sheep liver fluke. A related parasite, Fasciola gigantica, also can infect people. Fascioliasis is found in all continents except Antarctica, in over 70 countries, especially where there are sheep or cattle
First phenotypic description of Fasciola hepatica/Fasciola gigantica intermediate forms from the human endemic area of the Nile Delta, Egyp In Egypt, this re-emerging disease is caused mainly by Fasciola hepatica and F. gigantica ( Lotfy et al ., 2002 ) . It is a serious disease of herbivorous animals ( Torgerson and Claxton, 1999 ), leading to huge economic losses in live-stock production, while human infection has long been seemed to be accidentally . Fascioliasis is a zoonotic disease and its causative agents are parasites, Fasciola hepatica and F. gigantica, flatworms or trematodes that mainly affect the liver
Fasciola hepatica and Fasciola gigantica are two main species of Fasciola which infect both human and animals. While F. gigantica is occurring mainly in tropical and F. hepatica in temperate areas, both species overlap in subtropical zones [ The interspecific cross-hybridization between F. hepatica and F. gigantica has been well known for many years and documented by molecular evidence by Agatsuma et al. (2000). This study aimed to identify and describe the liver fluke (Fasciola) parasitizing buffaloes, cows and sheep in Qena Governorate, Egypt First phenotypic description of Fasciola hepatica/Fasciola gigantica intermediate forms from the human endemic area of the Nile Delta, Egypt.

Fascioliasis is a plantborne and zoonotic parasitic disease caused by fasciolid liver flukes. Fasciola hepatica is the only fasciolid species described in the Americas. Human fascioliasis endemic areas are mainly located in high altitude areas of the Americas. Given the necessity to characterize F. hepatica populations involved, the phenotypic and genotypic features of fasciolid adults. Fasciola hepatica •Commonly called 'sheep liver fluke'. •In sheep, the migratory phase of the parasite produces severe parenchymal disease of the liver for which the parasite is called sheep liver fluke and the disease is known as liver rot. 3 The Adult Worm - Averaging 30mm in length and 13 mm in width, Fasciola hepatica is one of the largest flukes in the world. The adult worm has a very characteristic leaf shape with the anterior end being broader than the posterior end and an anterior cone-shaped projection Fasciola hepatica is hermaphrodite. The gonads are well developed and the male and female genital ducts open into a common chamber, the genital atrium. It is situated anteriorly in the body and opens to the exterior through the common genital aperture or gonopore, located ventrally in front of the acetabulum. 1 Fasciola hepatica, TGF-β and host mimicry: the enemy within.

Fasciola hepatica is commonly known as the sheep liver fluke and is a common parasite in herbivores. With cosmopolitan distribution, human infections have been reported in many parts of the world. Fasciola hepatica is most frequently found in countries where sheep raising is common, such as China, Taiwan, India, Indonesia and other parts of Asia 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 Fascioliasis is a parasitic disease caused by the flukes, Fasciola hepatica and F. gigantica (Trematoda: Fasciolidae).

Abstract. Fasciola hepatica infection affects several animal species and is most often diagnosed in sheep and cattle. Fascioliasis presents nonspecific symptoms; therefore, laboratory diagnosis is required, with faecal examinations being the most frequently used as they are inexpensive, can be performed more easily and provide important epidemiological information Fasciola hepatica is a Platyhelminthic flatwork known as the liver fluke of sheep. It has been an important parasite of sheep and cattle for hundreds of years. People become infected from eating plants from wet places, such as watercress. Fasciola hepatica can cause fever, liver damage, and may make its way into the brain Zoonotic trematode infections are an area of the neglected tropical diseases that have become of major interest to global and public health due to their associated morbidity. Human fascioliasis is a trematode zoonosis of interest in public health. It affects approximately 50 million people worldwide and over 180 million are at risk of infection in both developed and underdeveloped countries Fasciola hepatica infections may not respond to praziquantel, unlike other flukes. Bithionol is available in most countries and is the only treatment, requiring a 5-10 day course of 30mg/kg body weight. But because of the high dose and high cost of the treatment it is difficult for large-scale use. Recently, triclabendazole has been proven to.

Fasciola hepatica infection is a zoonosis mostly encountered in the sheep-raising countries (2). Adult Fasciola hepatica lives in small passages of the liver of many kinds of mammals, particular Fasciola hepatica and Echinococcus granulosus, which are helminths of ungulates, frequently coinfect cattle. The effects of this particular type of polyparasitism are not well documented. The metacestode of Echinococcus granulosus is surrounded by the adventitial layer, which constitutes the host immune response to the parasite
Iran is amongst endemic countries for Fasciola hepatica. Individuals can become infected by consumption of contaminated uncooked green vegetables.

Fascioliasis, an uncommon liver disease in children, is caused by the trematode Fasciola hepatica. Its clinical and laboratory findings may mimic several disorders of the liver, including malignancies. Diagnosis is usually made by demonstrating the presence of the parasite in.. Abstract. The IgG immunoglobulin levels and the immune response to Fasciola hepatica digestive tract antigens were studied in experimentally infected lambs. A synchronic increase and decrease of IgG-1 serum levels and indirect fluorescent antibody titres were observed during the course of the infection. Antibody activities were demonstrated in. We have demonstrated the presence of miRNA s in the EV s of the trematode species Dicrocoelium dendriticum and Fasciola hepatica (Fhe) and identified potential immune‐regulatory miRNAs with targets in the host. After our initial identification of miRNAs expressed by F. hepatica , an assembled genome and additional miRNA data became available. The major pathogenesis associated with Fasciola hepatica infection results from the extensive tissue damage caused by the tunnelling and feeding activity of immature flukes during their migration, growth and development in the liver. This is compounded by the pathology caused by host innate and adaptive immune responses that struggle to simultaneously counter infection and repair tissue damage De leverbot (Fasciola hepatica) is een platworm uit de familie Fasciolidae en de orde Digenea.Het is een parasitaire platworm met een ingewikkelde levenscyclus. Volwassen leverbotten leven in de lever en galwegen van hun gastheer (een herkauwer, bijvoorbeeld een schaap).Volwassen leverbots produceren duizenden eitjes die via de ontlasting het lichaam verlaten
Fasciola hepatica is a helminth (worm) parasite with a world-wide distribution. Although traditionally regarded as a parasite of livestock, particularly sheep and cattle, that results in a large economic loss to the agricultural community it has recently emerged as an important human infection in many regions of the world,. The eggs are passed in the feces of mammalian hosts and, if they enter freshwater, the eggs hatch into miracidia. • It tends to be more oblong with a longer rounded posterior end as compared to broadly pointed posterior end of F.hepatica.
