What's unique about Taenia spp. and IHs??

Very specific to the IH they infect. e.g.Human infecting: T. solium (pork only) and T. saginata (beef only)

DH? IH? Metacestode features? Predilection sites?

Summary of hosts, metacestode features of Taenia spp.

Life cycle of Taenia solium

(Pork tapeworm) \* pigs eat human faeces \* lack of hygiene \* developing countries

Taenia solium

Risk factors for cysticercosis

Cysticercosis in humans

undercooked pork= develop adult worms veggies contaminated by the eggs = cyst stage

Prevention and control of Taenia solium

\* Treat pigs with oxfendazole

Taenia solium

Life cycle of Taenia saginata

"Beef measles"

Taenia ovis or "sheep measles"

Taenia hydatigena

Taenia pisiformis

Taenia taeniaeformis

zoonosis

Neuro coenurosis (Taenia)

Diagnosis of Taenia in Definitive Host... what about the eggs of Taenia and Echinococcus? What is key about the length? Scolex? And reproductive organs?
