How does Dicrocoelium Dendriticum cause disease?

Dicrocoelium dendriticum spends its adult life inside the liver of its host. After mating, the eggs are excreted in the feces. The first intermediate host, the terrestrial snail (Cochlicopa lubrica in the United States), consumes the feces, and becomes infected by the larval parasites.

What is the intermediate host of Dicrocoelium Dendriticum?

Intermediate hosts of Dicrocoelium spp. Like all trematodes, Dicrocoelium spp. requires a snail as a first intermediate host. Over 50 species of land snail may serve as the first intermediate host. The second intermediate host is an ant, usually in the genus Formica, although other genera may serve as a host.

How many hosts does Dicrocoelium Dendriticum have in its life cycle?

The Lancet liver fluke (Dicrocoelium dendriticum) has a rather complex life cycle that includes two intermediate hosts and one definitive host.

What type of parasite is a liver fluke?

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 infective stage of Fasciola hepatica?

Metacercariae are quiescent infective stages which can survive on aquatic vegetation or in water for several weeks. Mammals become infected when they ingest metacercariae with food or water (many human infections have been linked to the consumption of watercress).

What is false fascioliasis?

False fascioliasis (pseudofascioliasis) refers to the presence of Fasciola eggs in the stool because of recent ingestion of contaminated liver (containing noninfective eggs).
