Learn more about Bing search results hereOrganizing and summarizing search results for youThe life cycle of Dicrocoelium dendriticum involves the following stages:- Adult stage: The fluke lives inside the liver of its host.
- Egg stage: After mating, eggs are excreted in the host's feces.
- Intermediate host: The terrestrial snail consumes the feces and becomes infected by the larval parasites.
- Metacercariae stage: Once ingested by the final host, the metacercariae excyst in the small intestine.
- Juvenile flukes: They migrate up the main bile duct and then to smaller ducts, where they begin laying eggs approximately 10–12 weeks after infection.
- Total life cycle duration: Approximately 6 months.
