Conclusions:

Finally, let me summarise: 1. Similar shifts in personality traits were observed in several independent sets of subjects with latent toxoplasmosis. 2. Most of traits were shifted in an opposite direction in men and women. 3. Existence of correlation between the amount of the shift and duration of toxoplasmosis suggests that toxoplasmosis induces the shift rather than personality profile influences on the probability of the Toxoplasma infection. 4. It cannot be decided yet whether the personality factor shift is the result of the manipulation activity of the parasite or only a byproduct of unspecific deterioration of the health in infected subjects.
