[Lifetime diagnosis of prion transmissive encephalopathies]

An original method for life-time diagnosis of Greutzfeldt-Jakob's disease, a neurodegenerative disease belonging to transmissive spongiform encephalopathies, is proposed. It consists in inoculation of the examined biological materials (blood serum and clot) into a continuous culture of the rat Gasser's node neurinoma, followed by passages and study of the inoculated culture by morphological methods and electron microscopy.
