It is known as the common liver fluke and causes a disease called fascioliasis. The adult female liver fluke parasite passes immature eggs in the bile duct and comes out into the environment through the faeces. The infective oocysts reside in food and water (2). CYCLE OF EVENTS IN FASCIOLA HEPATICA• The life cycle of Fasciola hepatica starts when a female lays eggs in the liver of an infected human. Immature eggs are discharged in the biliary ducts and taken out in the feces. If landed in water, the eggs become embryonated and develop larvae called miracidia. It takes about 5-7 weeks for the parasite to develop in the snail and develops into sporocysts, rediae and finally cercariae. d. ... Fasciola hepatica - Life cycle.

Copulation, Fertilization and Capsule Formation: Under favorable conditions, non-parasitic stage larvae can persist on pastures for up to a year. This leads to rapid spore multiplication and the mass release of toxin. Fasciola hepatica is also known as sheep liver fluke as it resides in the liver and bile ducts of sheep. Apr 9, 2016 - This Pin was discovered by Somaiya alwaniss. Eggs become embryonated in water (2), eggs release miracidia (3), which invade a suitable snail intermediate host (4), including the genera Galba, Fossaria and Pseudosuccinea.

Definitive hosts of the fluke are cattle, sheep, and buffaloes. It is found in domestic and wild ruminants; deer are the reservoir host. Fascioliasis is a worldwide problem caused by the liver fluke (Dalton, 1999; Hurtrez et al., 2001).In Egypt, this re-emerging disease is caused mainly by Fasciola hepatica and F.gigantica (Lotfy et al., 2002). Hepatica is the usual cause of fascioliasis. It is commonly known as the beef tapeworm or cattle tapeworm because it uses cows as intermediate hosts. Vector red life cycle arrow diagram.
