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.

Science Asia On day 10 post incubation, the mature sporocyst transformed to become a young redia, with the visible pharynx and primitive gut, the unique characteristics of the redia no.

Fasciola gigantica is leaf-shaped and tapers at both ends.


Enterobius vermicularis Enterobiasis Pinworm. D Egg with escaping miracidium. Sexually mature adult flukes were recovered from day 42 PI.

Adult flukes were observed in the intestine and liver, and worm recovery and adult maturity were examined. Help us improve the site by taking our survey. On day 24, daughter rediae and young cercariae became fully developed no. Synapomorphy of the Anthozoa. Rice plants were examined for the presence of metacercariae both by naked eyes and with a stereomicroscope. One exposed snail was crushed daily to observe the larval stages until cercarial-shedding occurred.

The life llife was completed when the metacercariae were eaten by a mammalian definitive host.


ADW: Fasciola gigantica: INFORMATION

The attack of a proteoplytic enzyme protein controls the opening of the operculum which allows the miracidium to exit the shelled embryo. This indicated that the giigantica of F. Antibody levels decrease to normal 6 to 12 months after chemotherapeutic cure and can be used to predict the success of therapy.

Specific antibodies to Fasciola may be detectable within 2 to 4 weeks after infection, which is 5 to 7 weeks before eggs appear in stool. A Metacercariae arrowhead adhered to the stem of the rice plant.

The most important intermediate host for F. Skip directly to search Skip directly to A to Z list Skip directly to navigation Skip directly to page options Skip directly to site content. If the miracidium are to come in contact with a snail it actively penetrates it.

The young sporocyst had packed germinal cells and eyespots no. Fasciola gigantica is a parasitic flatworm of the class Trematodawhich causes tropical fascioliasis. One-month-old non-parasitized snails, L.

Suksan Chuboon for their laboratory assistance. However, the testes and ovary were discovered on day 27 PI, and they developed to maturity on day 39 PI. The time it takes for the shelled embryos of Fasciola gigantica to hatch is rapidly increased in the presence of light.

Each germinal cell gives rise to new germinal cells and these then multiplies to become germinal balls. Fascioliasis is caused by Fasciola hepatica and less often by F. Juvenile worms were detected in intestines of mice at days 3 and 6 Gjgantica, but they were found in the bile duct from day 9 PI.

Intermediate hosts of Fasciola spp. Fasciola gigantica also has three different types of surface papillae which are used as sensory receptors. We would like to thank Ms.

During the acute phase caused by the migration of the immature fluke through the hepatic parenchymamanifestations include abdominal pain, hepatomegaly, fever, vomiting, diarrhea, urticaria and eosinophilia, and can last for months.

Johnson and Thieltges, Ecosystem Roles Fasciola spp. Waraporn Noikong and Mr.


Faaciola germinal cell in the sporocyst developed and formed into the germinal ball on day 14 post incubation no. Treatment information for fascioliasis can be found at: The trematodes Fasciola hepatica the sheep liver fluke and Fasciola giganticaparasites of herbivores that can infect humans accidentally.

Infection with Fasciola spp. Eggs become gigantcia in watereggs release miracidiawhich invade a suitable snail intermediate hostincluding the genera Galba, Fossaria and Pseudosuccinea. Fasciola gigantica causes outbreaks in tropical areas of southern Asia, Southeast Asia, gigaantica Africa.

These parasites are the main cause of fascioliasis in ruminants and humans. The habitat of Fasciola gigantica changes with the stage of its life cycle.

It is also a common parasite of cattle, camels, and other herbivores in Africa and of herbivores in some Pacific islands.
