In nature every species that are not on top of food chain stay away from their natural predators. This behavior is in their genes and no one can change it. They do it by detecting the smell and sound of predators.
What happen if their natural behavior altered by some parasite? Obviously they become easy prey for their predators. They will not protect themselves and roam in predator territory.
Toxoplasma Gondii is only known parasite that can manipulate the behavior of mouse in other word this parasite control mind of mouse for own survival. Cat urine act as natural deterrent to rats and by smelling it rats knows the presences of cat in specific area and keep distance from them.
But mouse infected from Toxoplasma parasite get attracted by cat and lose their fear of cat. Whenever rat exposed to cat urine then their brain act differently .Parts of cat that govern sexual attraction become active and the same time brain region that handles fear get paralyzed. As a result mouse not afraid of cats and sexually attracted to them.
Toxoplasma Gondii require cat digestive system to complete his life cycle. This parasite does sexual development and reproduction in cat’s small intestine and when cat excrete feces then it contaminates the water, soil ,food and anything that contact with it.
When this parasite come out from cat’s body through feces then for completing his life cycle he again requires cat digestive system. For fulfilling this need parasite control mouse mind by infecting him and expose him in front of cat. Cat eat infected mouse, with this action Life cycle of Toxoplasma parasite completes.
Human can also get infected by Toxoplasma parasite by organ transplant or blood transfusion or by eating unwashed fruits or vegetables. The most potential cause of infection is a cleaning cat litter boxes.
Controlling mind and diverting any species to cause of death seems paranormal activities. No one knows why this parasite chose to cat only for reproduction? And why this parasite adopts weird way to reach in cat body digestion system?
If scientists find the way to control the mind then in future we will control mind of animals and take desire work from them.
