What disease does Fasciolopsis buski cause?

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.

How is f Buski infection 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 is the mode of transmission of Fasciolopsis buski?

No, Fasciolopsis is not transmitted directly from human to human. Humans (and pigs) pass eggs in their feces, which develop in water and infect snails as intermediate hosts. After further development, the parasites leave the snail intermediate host and encyst on water plants.

Where does Fasciolopsis buski come from?

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. Fasciolopsiasis is treatable.

What does Fasciola hepatica cause?

Fascioliasis is a parasitic infection typically caused by Fasciola hepatica, which is also known as “the common liver fluke” or “the sheep liver fluke.” A related parasite, Fasciola gigantica, also can infect people.

What is the largest trematode?

The largest of the major hermaphroditic trematode species is Fasciola hepatica (approximately 35 mm by 15 mm) and the smallest is P. westermani (10 mm by 5 mm). Adult schistosomes have a somewhat greater length to width ratio, with males measuring approximately 10 mm by 1 mm and females 15 mm by 0.2 mm.

What are the symptoms of Fasciola hepatica?

What is the mode of transmission of Fasciola hepatica?

Transmission occurs through the ingestion of raw, fresh-water vegetation on which the flukes in their metacercariae form are encysted. The plants become exposed to the metacercariae when the body of water that the vegetation is growing in becomes contaminated by eggs in the fecal matter of an infected host.

What is the life cycle of Fasciola hepatica?

Life cycle of Fasciola hepatica. Immature Fasciola eggs are discharged in the biliary ducts and in the stool (1). Eggs become embryonated in water (2), eggs release miracidia (3), which invade a suitable snail intermediate host (4), including the genera Galba, Fossaria and Pseudosuccinea.

How do I know if I have liver flukes?

Symptoms of Fluke Liver Infections At first, liver flukes may cause no symptoms, or depending on the type and severity of the infection, they may cause fever, chills, abdominal pain, liver enlargement, nausea, vomiting, and hives. Fasciola flukes are more likely to cause these symptoms.

What happens if parasites are left untreated?

Where do blood flukes live?

Blood fluke, any of certain parasitic flatworms that live in the veins of the host organism.

Can you tell the difference between Fasciola hepatica and f.buski?

The eggs of F. buski can be difficult to distinguish from Fasciola hepatica, although the abopercular end of the latter often has a roughened or irregular area. Figure A: Egg of F. buski in a unstained wet mount. Figure B: Egg of F. buski in a unstained wet mount.

How big is the adult fluke of Fasciolopsis buski?

Fasciolopsis buski adults. Adults of F. buski measure 20-75 mm long and have poorly-developed oral and ventral suckers. Adults reside in the intestine of the mammalian host. Figure B: Adult fluke of F. buski. Figure A: Adult fluke of F. buski. Image contributed by Georgia Division of Public Health. Intermediate hosts of F. buski.

What are the symptoms of Fasciolopsis buski eggs?

The adults have a life span of about one year. Asia and the Indian subcontinent, especially in areas where humans raise pigs and consume freshwater plants. Most infections are light and asymptomatic. In heavier infections, symptoms include diarrhea, abdominal pain, fever, ascites, anasarca and intestinal obstruction. Fasciolopsis buski eggs.

What can be done about the growth of Fasciola?

Strict control of the growth and sale of watercress and other edible water plants is important. Individual people can protect themselves by not eating raw watercress and other water plants, especially from Fasciola -endemic grazing areas.
