Quick Answer: The Prevalence Of Fasciolopsiasis In Southeast Asia Is High In Populations Which Consume Snails?

What is fasciolopsiasis?

Fasciolopsiasis is infection with the intestinal fluke Fasciolopsis buski, which is acquired by eating aquatic plants or ingesting contaminated water. Flukes are parasitic flatworms that infect various parts of the body (blood vessels, gastrointestinal tract, lungs, liver) depending on the species.

What is the causative agent of fasciolopsiasis?

Fasciolopsiasis is caused by infection with the intestinal fluke Fasciolopsis buski.

What is parasites Fasciolopsis?

Parasites – Fasciolopsiasis (Fasciolopsis infection) The intestinal fluke Fasciolopsis buski, which causes faciolopsiasis, is the largest intestinal fluke of humans. Fasciolopsiasis can be prevented by cooking aquatic plants well before eating them. Fasciolopsis is found in south and southeastern Asia.

How is Fasciolopsis buski diagnosed?

Diagnosis of fasciolopsiasis is made by finding eggs or, less commonly, adult worms in the feces. The eggs are indistinguishable from those of Fasciola hepatica. Treatment of fasciolopsiasis is with praziquantel 25 mg/kg orally 3 times a day for 1 day.

What causes Paragonimiasis?

Parasites – Paragonimiasis (also known as Paragonimus Infection) Paragonimus is a lung fluke (flatworm) that infects the lungs of humans after eating an infected raw or undercooked crab or crayfish. Less frequent, but more serious cases of paragonimiasis occur when the parasite travels to the central nervous system.

What causes Fasciola hepatica?

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 Fasciolopsis Buski found in the body?

Fasciolopsis buski adults. Adults reside in the intestine of the mammalian host.

How is Fasciola hepatica diagnosis?

The infection typically is diagnosed by examining stool (fecal) specimens under a microscope. The diagnosis is confirmed if Fasciola eggs are seen. More than one specimen may need to be examined to find the parasite. Certain types of blood tests also may be helpful for diagnosing Fasciola infection.

What is the life cycle of Fasciola hepatica?

Fasciola pass through five phases in their life cycle: egg, miracidium, cercaria, metacercaria, and adult fluke. The eggs are passed in the feces of mammalian hosts and, if they enter freshwater, the eggs hatch into miracidia. Miracidia are free-swimming.

How Fasciolopsis is different from fasciola?

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.

What type of parasite is Fasciola hepatica?

F. hepatica is a trematode (fluke) parasite that infests humans and many species of animals. F. hepatica is the usual cause of fascioliasis.

Which is the largest trematode?

The trematode Fasciolopsis buski, the largest intestinal fluke of humans.

How is Fasciola hepatica treated?

Triclabendazole. 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 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.
