Fasciolopsiasisinfection of humans and swine by the trematode Fasciolopsis buskia parasitic worm. The adult worms, 2—7. In the early stage of the infection, there is usually abdominal pain, as well as diarrhea and nausea alternating with constipation.
Only one species is recognised: Fasciolopsis buski. It is a notable parasite of medical importance in humans and veterinary importance in pigs. It is prevalent in Southern and Eastern Asia.
Immature eggs are discharged into the intestine and stool. Eggs become embryonated in watereggs release miracidiawhich invade a suitable snail intermediate host. In the snail the parasites undergo several developmental stages sporocystsrediaeand cercariae.
Fasciolopsiasis is infection with the intestinal fluke Fasciolopsis buskiwhich is acquired by eating aquatic plants. Flukes are parasitic flatworms that infect various parts of the body blood vessels, GI tract, lungs, liver depending on the species. Human infection is acquired by eating aquatic plants eg, water chestnuts that bear infectious metacercariae encysted stage.
This trematode is especially prevalent in areas where pigs are raised, or where underwater vegetables such as water chestnut, water caltrop, lotus, and bamboo are often consumed. Fasciolopsis buski occurs in places with warm, moist, weather. This species is found in aquatic environments, where aquatic plants grow.
Fasciolopsiasis is a disease caused by Fasciolopsis buski where humans acquire the infection by consumption of raw fresh water plants contaminated with metacercariae stage of the parasite. We are reporting an unusual case, in which an year-old boy vomited out 4 live adult worms. The patient had complains of occasional gastrointestinal symptoms.
Fasciolopsis buski is a very large fluke that lives in the small intestine of humans and pigs in various Southeast Asian countries and China. This fluke has also been found in people in Hawaii. The eggs are very similar to those of the large liver fluke, Fasciola hepaticawhich makes the diagnosis based on eggs in the feces quite difficult. Fasciolopsis buski has a life cycle that does not require the ingestion of a host by the human final host.

Fasciolopsiasis is rarely known as the parasitic disease in Nepal. Herein, we report a case of fasciolopsiasis in a year-old man who was admitted in the hospital with abdominal pain, distension and loss of appetite for a month. He had previously diagnosed with acute viral hepatitis but, his abdominal pain was not resolving despite improvement in his liver function and general condition.
