The life cycle of Fasciola gigantica is as follows: eggs (transported with feces) → eggs hatch → miracidium → miracidium infect snail. Life ca passes its life cycle in two different hosts. • Definitive hosts- Sheep,goat, cattle or man. Adult worm in the biliary passages of the liver. Keywords: Fasciola gigantica, life history, biological characteristic, The general life cycle of fasciolids is described in the following passage.

The cercariae are released from the snail and encyst as metacercariae on aquatic gigantifa or other surfaces. December 8, Content source: Lymnaea auricularia rubiginosa was used as the intermediate lice, and Oryza sativa was used for encystment of the metacercariae, while Mus musculus was used as the definitive host for maturation study.

Ingestion of Fasciola gigantica metacercariae by the intermediate host snail, Lymnaea ollula, and infectivity of discharged metacercariae. Embryos of Fasciola species are able to persist outside the host for several months.

The habitat of Fasciola gigantica changes with the stage of its life cycle.

Fasciolidaeis important as a plant-borne trematode together with the sheep liver fluke, Fasciola hepatica. The metacercariae of F. Immature Fasciola eggs are discharged in the biliary ducts and in the stool. After 1 or 2 days, the cyst gradually becomes yellow and darkens in color Fig.

In otherwords, Europe and Asia and northern Africa. The mother redia contain many daughter rediae and germinal balls Fig.

Fasciola hepatica and Paramphistomum giganitca Sixteen albino mice Mus musculus domesticus were used as the experimental definitive host. Parasitol al Dia ; On day 7 post incubation, the young sporocyst transformed to become a mature sporocyst, redia-like in shape, but with no pharynx or primitive gut no.

Our findings show that L. Eggs become embryonated in watereggs release miracidiawhich invade a suitable snail intermediate hostincluding the genera Galba, Fossaria and Pseudosuccinea.

ADW: Fasciola gigantica: INFORMATION

The metacercariae exist in the small intestineand move through the intestinal wall and peritoneal cavity to the liver where adults mature in the biliary ducts of the liver. How ecological communities affect disease risk. Adults of Fasciola hepatica are large and broadly-flattened, measuring up to 30 mm fascila and 15 mm wide. Cobbold[1].

Serological diagnosis of Fasciola hepatica. At this point, the cercariae lost their tails and developed into the metacercarial stage Fig. January 10, Page last updated: The larvae are transmitted to the intermediate hosts, which in many cases are vegetation, as well as to the definitive hosts. Adequate amounts of moisture are also needed, these giganrica can account for the intensity and prevalence of infection in the definitive hosts. Cyycle is also a common parasite of cattle, camels, and other herbivores in Africa and of herbivores in some Pacific islands.



The surface is completely occupied with cilia. This aspect has not been studied in Thailand, and most reports were focused on the epidemiology and molecular detection of Gasciola. In humans, maturation from metacercariae into adult flukes takes approximately 3 to 4 months. Fasciola hepatica infect various animal species, mostly herbivores plant-eating animals. Fasciola gigantica also has three different types of surface papillae which are used as sensory receptors. Species of the freshwater snails from the family Lymnaeidae are well known for their role as intermediate hosts in the life cycle of Fascciola gigantica ; however, throughout gigantoca years an increasing number of other molluscan intermediate hosts of F.

Confirmation of the infection depends on finding the operculated eggs in a routine stool examination; multiple stool examination may be required to find the eggs.

Humans are infected by ingestion of uncooked aquatic vegetation on which metacercariae are encysted. January 10, Content source: This situation with its potential for misdiagnosis can be avoided by having the patient follow a liver-free diet several days before a repeat stool examination. Secernentea Spiruria Camallanida Dracunculus medinensis Dracunculiasis.

Life Cycle Immature eggs are discharged in the biliary ducts and in the stool. Temperatures above 10 degree Celsius are required for the development of the miracidia larvae stage.
