Question

Toxoplasmosis is a disease caused by the microscopic parasite Toxoplasma gondii. The parasite usually infects mice, affecting their nervous system and causing them to take unusual risks (such as running out in the open, and coming unusually close to animals which may eat them). Scientists believe this is actually a way for the parasite to reach its primary host – cats. When a cat catches and eats an infected mouse, the Toxopasma gondii enters its digestive system and steals nutrients from the cat. Humans can become infected by Toxoplasma gondii through contact with cat feces. Scientists now believe that Toxoplasmosis in humans can cause substantial changes in mood and behavior, and may even be linked to certain types of depression. It is estimated that 30-65% of people worldwide may be infected with Toxoplasma gondii. 9. Based on the story above, discuss how the organisms interact with each other. In your response, be sure to: o Identify at least TWO different symbiotic relationships involved in Toxoplasma gondii transmission and explain each

Answer 1

Answer:

Scientists have previously shown that a parasite from cats can infect people's brain and affect our behaviour. Now, researchers at Stockholm University have discovered how the parasite takes control of our cells.
