Toxoplasma gondii has been found in the kidneys, bladder and intestine of infected humans. There have been rare cases of organ transplant recipients acquiring toxoplasmosis infection.

What does toxoplasmosis smell like?

Toxoplasma-infected subjects rate the pleasantness of smell of highly diluted urine of the definitive host of Toxoplasma, the cat, but not the pleasantness of smell of urine of other four species, differently than the non-infected controls (Flegr et al., 2011).

How do you know if you have Toxoplasma gondii?

Symptoms of the infection vary. Most people who become infected with Toxoplasma gondii are not aware of it because they have no symptoms at all. Some people who have toxoplasmosis may feel as if they have the “flu” with swollen lymph glands or muscle aches and pains that may last for a month or more.

Does toxoplasmosis control your brain?

No, but they may make you less afraid of risk. There’s a single-celled parasite called Toxoplasma gondii, and it can turn a normally risk-averse mouse into a bold, cat-seeking rodent.
