Tapeworms in cats

Question
How does a cats immune system combat the tapeworms?
It is for a college assignment please help :)

Answer
For a paper you need citations, so I suggest you research immunology texts and parasitology texts. I am a practicing veterinarian, not an expert on the immune system.

Since I have holistic training, I will give you some interesting opinions you could also use in your paper. Be sure you emphasize the amazing varieties of tapeworm intermediate and final hosts that tapeworms have. When a cat ingests a mouse or a flea, the infective larvae is in the stomach, so the pH of 1 (acid) can kill the tapeworms larvae right then. If they pass into the intestines and adhere to the lumen, it is harder for the immune system to kill them. If the intestinal tract is very healthy (because a raw meat diet is fed), there will be less mucus (mucus is generated as an allergic response to processed foods and grains) and tapeworms need mucus to adhere. Many herbs can kill the worms at this point, so drugs may not be needed. A British natural healer, Juliette de Bairacli Levy, speaks of this in her book the complete herbal handbook for the dog and cat, page 273 in my edition. She gives specifi  herbal treatments for even recalcitrant tapeworm infestations.
Hope this helps you a bit.
