Adult flukes reside in the small intestine, where they mature and produce eggs. These eggs are then passed into the host's feces where they will continue the life cycle of the parasite. Treatment involves anthelmintic medications to rid the flukes from the intestines. Early diagnosis and treatment are essential in preventing further ...
Microscopic identification of eggs, or more rarely of the adult flukes, in the stool or vomitus is the basis of specific diagnosis. The eggs are indistinguishable from those of the very closely related Fasciola hepatica liver fluke, but that is largely inconsequential since treatment is essentially identical for both.

Metagonimiasis is a disease caused by an intestinal trematode, most commonly Metagonimus yokagawai, but sometimes by M. takashii or M. miyatai.The metagonimiasis-causing flukes are one of two minute flukes called the heterophyids.
Fasciola hepatica, a species of liver flukes, has a higher incidence rate in children and females, with more cases of lung fluke and intestinal trematodiases in children. [5] Cases of liver and lung fluke trematodiasis are frequent due to the length of time the trematode can live in host organisms, and increased chances of reinfection. [9]
The adult flukes can cause inflammation and damage to the intestinal wall, leading to various symptoms. Symptoms of fasciolopsiasis may vary from mild to severe, depending on the extent of the infection. Common symptoms include abdominal pain, diarrhea, nausea, vomiting, bloating and weight loss. In some cases, the infection may be asymptomatic ...
After the penetration of the intestine, flukes migrate within the abdominal cavity and penetrate the liver or other organs. F. hepatica has a strong predilection for the tissues of the liver. [17] Occasionally, ectopic locations of flukes such as the lungs, diaphragm, intestinal wall, kidneys, and subcutaneous tissue can occur.
Lung flukes require three different hosts in order to complete their life cycle. The first intermediate host is a snail, the second intermediate host is a crab or crayfish, and the definitive host for lung flukes is an animal or human host. [4] Intestinal flukes inhabit the epithelium of the small intestine.
Echinostoma is a genus of trematodes (flukes), which can infect both humans and other animals.These intestinal flukes have a three-host life cycle with snails or other aquatic organisms as intermediate hosts, [2] and a variety of animals, including humans, as their definitive hosts.
