[Diagnosis and treatment of toxoplasmosis by means of radionuclide].

Using antibodies against Toxoplasma gondii labelled with indium-113 metaestable we obtained scan of rats infested with this disease in a simple and harmless way. Also using the same antibodies, but labelled with iodine-131, we destroyed by radiolysis the toxoplasmas of experimental animals with the Medial Lethal Dose obtained "in vitro" experiments. The experimental results are very encouraging and their use in human beings are in currently research in our laboratory and will be the object of a future communication.
