[Immune response to toxoplasma infection]. / La risposta immunitaria in corso di infezione toxoplasmica.

The Authors studied the response of 49 subjects (23 affected by toxoplasmosis, 6 with systemic lymphopaties, and 20 apparently healthy controls) to the stimulation of lymphocytes both with an aspecific mitogen (PHA) and a specific one (toxoplasma antigen). No difference was found in the response to PHA, but when the specific antigen was used, patients with toxoplasmosis showed a significant increase of the lymphocytes stimulation index when compared to patients with systemic lymphopaties and to controls.
