Fasciolopsis buski
Fasciolopsis buski
Fasciolopsis buski (pronounced: fas-ee-oh-lop-sis bus-kee) is a large intestinal fluke that is known to infect humans and pigs. It is one of the largest trematodes infecting humans, typically found in the small intestine. The infection is known as Fasciolopsiasis.
Etymology
The term "Fasciolopsis" is derived from the Latin "fasciola" meaning "little band" and the Greek "opsis" meaning "appearance". "Buski" is named after the scientist who first described the species, Dr. Busk.
Life Cycle
The life cycle of Fasciolopsis buski involves two hosts: a definitive host (humans or pigs) and an intermediate host (snails). The adult flukes reside in the small intestine of the definitive host. Eggs are excreted in the feces and, if they reach water, they hatch into miracidia, which infect a suitable snail host. In the snail, the parasites undergo several developmental stages (sporocysts, rediae, and cercariae). The cercariae are released from the snail and encyst as metacercariae on aquatic plants. Humans or pigs become infected by ingesting the metacercariae on the contaminated plants.
Symptoms and Treatment
Infection with Fasciolopsis buski can be asymptomatic or can cause a range of symptoms, including abdominal pain, diarrhea, and edema. Severe infections can lead to intestinal obstruction. The infection is diagnosed by finding eggs in the stool. Treatment typically involves the drug Praziquantel.
Prevention
Prevention of Fasciolopsis buski infection involves proper sanitation and avoiding eating raw or undercooked aquatic plants.
