Where is Fasciola hepatica found in sheep?
Fasciola hepatica occurs in the liver of a definitive host and its lifecycle is indirect. Definitive hosts of the fluke are cattle, sheep, and buffaloes. Wild ruminants and other mammals, including humans, can act as definitive hosts as well.
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.
Where is Fasciola Gigantica found in the body?
Adults of Fasciola hepatica are large and broadly-flattened, measuring up to 30 mm long and 15 mm wide. The anterior end is cone-shaped, unlike the rounded anterior end of Fasciolopsis buski. Adults reside in the bile ducts of the liver in the definitive host.
How is human infection created with 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.
What are the symptoms of Fasciola hepatica?
More usually the invasive phase lasts many weeks, with the most common symptoms being intermittent fever, hepatomegaly, and abdominal pain, although up to 50% of infections may be subclinical. Abdominal pain is usually in the epigastrium or right hypochondrium. Other symptoms include malaise and wasting.

What disease does clonorchis 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.
How do you treat Fasciola gigantica?
Triclabendazole, a benzimidazole compound active against immature and adult Fasciola parasites, is the drug of choice for treatment of fascioliasis. In February 2019, the U.S. Food and Drug Administration (FDA) approved triclabendazole for treatment of fascioliasis in patients at least 6 years of age .
What disease does Fasciola gigantica cause?

How do sheep get Fasciola hepatica?
Once ingested by sheep, the immature fluke burrow through the gut wall and pass to the liver. They are voracious feeders and migrate through the liver parenchyma to reach the bile duct, where they mature.
