Increase of reaction times with decrease of antibody titres (i.e. with duration of toxoplasmosis)

What was again very important: The decrease of psychomotor performance correlated with the decrease of anti-Toxoplasma antibody titres, therefore with the duration of latent toxoplasmosis. It suggests that the decrease of psychomotor performance is not some transient after-effect of acute toxoplasmosis but rather a cumulative effect of the latent toxoplasmosis. We must, however, stress that the increase of reaction times can be in fact interpreted either as a symptom of deterioration of health of infected subjects or as a specific product of manipulation activity of the parasite. It is self-evident, that particularly an increase of reaction time of an intermediate host (under natural conditions a mouse) can highly increase the probability of transmission of Toxoplasma into the definitive host, the cat by predation.
