What are the characteristics of Fasciola?

Morphology: 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.

How are humans infected by Fasciola?

People usually become infected by eating raw watercress or other water plants contaminated with immature parasite larvae. 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.

Where is Fasciola found?

The adult (mature) flukes are found in the bile ducts and liver of infected people and animals, such as sheep and cattle. In general, fascioliasis is more common in livestock and other animals than in people. Two Fasciola species (types) infect people.

Why Fasciola is called liver fluke?

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.

How do Fasciola eat?

Fasciola hepatica is acquired by eating aquatic vegetation on which metacercariae are attached. Upon ingestion the metacercariae are released, penetrate the gut wall, traverse the peritoneal cavity, pass through the liver capsule into the liver parenchyma and enter the bile duct.

What is the classification of Fasciola?

Flukes Fasciola / Class Fasciola hepatica is a trematode (fluke) of the phylum Platyhelminthes. Together with other parasitic trematodes such as Paragonimus westermani and Clonorchis sinensis, it is classified under tissue flukes since it infests the tissues of its definitive host, such as mammals and humans.

Is Fasciola free living?

Adults live in the bile ducts of their mammalian host. Their eggs enter the host gut and are passed on with feces. They hatch to form free-living egg larvae or miracidia, which can live only a few hours in water.

Is Fasciola a tapeworm?

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). …

Fasciolosis
Frequency 2 millions

Can you poop out liver flukes?

Diagnosis of Fluke Liver Infections Doctors diagnose Clonorchis, Opisthorchis, or Fasciola infections when they see fluke eggs in a person’s stool (feces) or in the contents of the person’s intestines. However, finding eggs in stool may be difficult.

How do you know when parasites are dying?

When this happens, we typically experience die-off symptoms, which could include headaches, diarrhea, increased fatigue, or vomiting. Although it may appear that you’re getting worse, die-off symptoms are actually positive signs of healing.

Can parasites damage liver?

Liver flukes are parasites that can infect humans and cause liver and bile duct disease. There are two families of liver flukes that cause disease in humans: Opisthorchiidae (which includes species of Clonorchis and Opisthorchis) and Fasciolidae (which includes species of Fasciola).

What are the symptoms of a liver fluke?

Symptoms of Liver Fluke

What disease does clonorchis sinensis cause?

Clonorchiasis is an infectious disease caused by the Chinese liver fluke (Clonorchis sinensis) and two related species. Clonorchiasis is a known risk factor for the development of cholangiocarcinoma, a neoplasm of the biliary system.

Is fasciola a zoonotic?

Etiology. Fascioliasis is a parasitic zoonotic infection caused by two trematode species: Fasciola hepatica and F. gigantica. Both are leaf-shaped and large enough to be visible to the naked eye.

Is Fluke a zoonotic?

Liver fluke can infect cattle, sheep and goats, as well as a range of other animal species. It is a zoonotic disease which means humans can also be infected.

What are flukes in poop?

A liver fluke is a parasitic worm. Infections in humans usually occur after eating contaminated raw or undercooked freshwater fish or watercress. After liver flukes have been ingested, they travel from your intestines to your bile ducts in your liver where they then live and grow.

Can parasites cause weight gain?

Because parasites come in so many different shapes and sizes, they can cause a very wide range of problems. Some consume your food (from inside your body), leaving you hungry after every meal and unable to gain weight.

How can Fascioliasis be prevented?

Individual people can protect themselves by not eating raw watercress and other water plants, especially from Fasciola-endemic grazing areas. As always, travelers to areas with poor sanitation should avoid food and water that might be contaminated (tainted).

What is economic importance of Fasciola?

Fasciolosis is an economically important disease of domestic livestock, in particular cattle and sheep and occasionally man. The disease caused by digenean trematodes of the genus Fasciola commonly referred to as liver fluke. The two species most commonly implicated, as the etiological agents of Fasciolosis are F.

Which is the first larval stage of Fasciola?

Miracidium Larva: It is the first larval stage in the life cycle of Fasciola hepatica.

Do liver flukes lay eggs?

Adult fluke lay eggs that are passed out onto pasture in the faeces. At suitable temperatures, a miracidium develops within the egg, hatches and migrates in thin films of moisture, actively seeking the snail host.

How many eggs do liver flukes lay?

After 34 months, the juvenile flukes reach the deep-seated bile ducts where they mature sexually and initiate egg production. The adults lay, on average, between 8000 and 25 000 eggs per day.

Who discovered liver fluke?

History Timeline of Discovery of F.hepatica
De Brie, 1379 First observation of cercariae in snail
Steenstrup, 1842 Elucidated the idea of an alternating generation in parasite development
Weinland, 1875 L. truncatula was determined as the intermediate host for the larval stage of the liver fluke

Is clonorchis hermaphroditic?

C. Clonorchis sinensis adults are flattened, lance shaped, and measure approximately 10 to 25 mm long by 3 to 5 mm wide. The oral and ventral suckers (acetabulum) are relatively small. Like other flukes, they are hermaphroditic.

What is the meaning of fasciola?

Medical Definition of fasciola 1 plural fasciolae -l or fasciolas : a narrow fascia or band of color. 2 capitalized : a genus (the type of the family Fasciolidae) of digenetic trematode worms including common liver flukes of various mammals (as ruminants and humans)

Is fasciola an Ectoparasite?

The adult form of the fasciola hepatica is seen in the vertebrate host and larval stages are seen in the invertebrate host and it mainly lives in the bile duct of the sheep. That is the reason why the fasciola hepatica is called a digenetic endoparasite.

Can liver flukes cause weight gain?

Once inside cattle, metacercariae migrate through the gut wall, cross the peritoneum and penetrate the liver capsule and bile ducts. Symptoms associated with liver flukes include reduced weight gain, reduced milk yields, reduced fertility, anemia, and diarrhea.
