Toxoplasmosis-associated difference in intelligence and personality in men depends on their Rhesus blood group but not ABO blood group
2013
Abstract
The parasite Toxoplasma gondii influences the behaviour of infected animals and probably also personality of infected humans. Subjects with a Rhesus-positive blood group are protected against certain behavioural effects associated with Toxoplasma infection, including the deterioration of reaction times and personality factor shift.
