Echinococcus granulosus life cycle (7)
- Embryonated egg in faeces - ingestion of eggs by intermediate host (sheep, goats, swine, horses)
- Oncosphere hatches - penetrates intestinal wall
- Hydarid cyst in liver, lungs (grow in diff tissues) - reach maturity after 6-12 months
- Ingestion of cysts (in organs - feed on offal from intermediate host) by definitive host (dogs + other carnivores)
- Protoscolex (tiny adult tapeworms) from cyst
- Scolex attaches to intestine
- Develop into adults in the small intestine
- PPP = 40-50 days in definitive host
- Humans = accidental intermediate hosts (hydatid cysts in lungs + tissues)
- Domestic and sylvatic cycles (between non-human primates (e.g., monkeys) and mosquito species found in the forest canopy)
Echinococcus multilocularis life cycle (4)
