cestodes/ flat worm
Start with the big picture
Cestodes include Taenia saginata, Taenia solium, Hymenolepis nana, Diphyllobothrium latum, and Echinococcus species. Their life cycles and routes of infection help explain important differences: T. solium eggs can lead to neurocysticercosis, while E. granulosus and E. multilocularis can form hydatid cysts. Other characteristic associations include vitamin B₁₂ depletion with D. latum and possible heavy-burden diarrhea with H. nana. The lesson also surveys diagnosis and treatment, distinguishing therapy for intestinal infection from management of tissue disease. It introduces praziquantel and albendazole mechanisms, key adverse effects, and monitoring considerations for prolonged albendazole treatment.
What you'll learn

- Distinguish major human-pathogenic cestodes by their clinical features.
- Explain how Taenia solium infection can lead to neurocysticercosis.
- Compare treatment approaches for intestinal cestodes and tissue infections.
- Identify key drug mechanisms, adverse effects, and monitoring considerations.
