  1. Cysticercosis (neurocysticercosis) BIOL 402 Janki Patel

  2. Cysticercosis is caused by tapeworms!

  3. Tapeworms are gross!

  4. Two different theories explain the origin of tapeworms. 1) Domestication of animals 10,000 years ago

  5. Two different theories explain the origin of tapeworms. 2) Scavenging of food 2 million years ago by African hominids

  6. Three types of tapeworms infect humans. • Taenia solium • Taenia asiatica • Taenia saginata

  7. Taenia solium causes cysticercosis.

  8. Pigs are intermediate hosts. • Feces → intestine → blood vessel → muscle

  9. Humans are final hosts. • Feces/meat → intestine → body

  10. A pork tapeworm cycle exists!

  11. The symptoms of cysticercosis are harsh!

  12. The pork tapeworm can live in an host for years without being noticed!

  13. Cysticercosis can be diagnosed several ways. • Travels • Eating • MRI or CT brain scans • Blood tests • Surgery

  14. Treatment depends on each individual case. • Anti-parasitic drugs • Anti-inflammatory drugs • Surgery

  15. Preventive measures have been taken against this disease.

  16. Yet, this preventable disease still infects and kills lots of people in the world!
