3 Questions
What is the pericyst?
A layer of fibrous tissue laid by fibroblasts around the hydatid cyst
Which hosts are involved in the life cycle of hydatid cysts?
Both definitive and intermediate hosts
What happens to old hydatid cysts?
They become sclerosed or calcified
Study Notes
- Some embryos develop into hydatid cysts
- Fibroblasts lay fibrous tissue around the cysts
- This is known as pericyst and provides nutrition to the parasite
- The embryo develops into a fluid-filled bladder inside the pericyst
- Brood capsules with scolices develop on the inner side of the cyst
- Improper disposal of viscera from intermediate hosts can lead to infection in definitive hosts
- Adult worms develop in the intestine of definitive hosts
- Eggs are passed in the feces of infected animals
- The life cycle comes to a dead end in dogs, as they cannot access hydatid cysts in humans
- Old cysts may become sclerosed or calcified, causing the parasite within to die.
