Presentation Transcript

1. Making the Human Body Feel Like Home Host-Parasite Interactions

2. Background Info on Parasites Excluding viruses and bacteria, parasites range in size from microscopic amoebas to large intestinal worms There are over 3200 types of parasites that can live inside the human body Exist in 4 very different categories Protozoa Cestodes Nematodes Trematodes There are about 100 species of parasitic worms

3. Background Info on Parasites Inside the human body, parasites enjoy our nutrients from the food we eat We get their leftovers & their waste Most parasites lack a brain but are highly specialized survival machines All of their daily energy is focused on eating & reproducing

4. Tapeworms & You There are a number of different species of tapeworms Bladder worms Pork tapeworms Broad fish Can grow up to 35 feet long & live 10 years in humans Dog tapeworms Dwarf & Rat tapeworms

5. Background Info on Parasites Cestodes More commonly known as the Tapeworm

6. Tapeworms & You

7. Tapeworms & You Life Cycle & Tapeworm development Two stages in the life cycle Life in the intermediate host Life in the definitive host The immature (larval) form of a tapeworm is found in its intermediate host These hosts include: Cows, Dogs, Pigs, etc. Host gets infected when they eat eggs passed in feces from humans

8. Tapeworms & You

9. Tapeworms & You The adult (sexually mature) form of the tapeworm is found in the definitive host Humans get infected when they eat the parasites when they are in an intermediate phase of development (Metacestode Stage) Physical Structure of Adults Bodies are in segments with hooks & suction cups on their heads The terminal segments fall off but are constantly being formed at the anterior end

10. Tapeworms & You

11. Tapeworms & You

12. Tapeworms & You Damage Tapeworms Can Cause Can make Swiss cheese out of organs Can erode, damage, or block certain organs by lumping together in balls Lumps can travel to the brain, heart, & lungs Can be mistaken for tumors Their waste can poison the body (Verminous Intoxification) Body has to work twice as hard to remove this toxic waste

13. Tapeworms & You

14. Tapeworms & You Damage Tapeworms Can Cause They rob humans of vital vitamins, minerals, & amino acids Degrade the immune system leads to fatigue & other illnesses Destroy cells faster then they can be regenerated

15. Tapeworms & You Tapeworm Reproduction Each segment contains a complete set of male & female reproductive organs that are able to produce sex cells Fertilization is internal Most species require cross-fertilization between two adjacent worms Some species can self-fertilize between two segments of the same worm Sometimes within the same segment

16. Tapeworms & You

17. Tapeworms & You Tapeworm Reproduction Some species are continuously shedding the fertilized eggs while others wait until a segment is filled with eggs & then the entire segment is shed Eggs leave the hostís body through the feces Eggs develop into embryos with hard outer shells that donít hatch until they are eaten by a suitable intermediate host Worms can release 3,000-1,000,000 eggs/day

18. Tapeworms & You Removal of Tapeworms Cleansing the colon by colonic irrigation using hydrogen peroxide & oxygenated water Worms can grow so long that they appear outside the anus Sometimes, the worm can be pulled out but this is not recommended because you run the risk of tearing the worm in half

19. Conclusions Humans and other organisms will always serve as hosts to foreign organisms Parasites will be in the body as long as we are around Tapeworms are a problem but medicine can help
