Each eosinophilic mass measures 10 mm and is made up of a finely fibrillar matrix and rabies virus particles. Negri bodies are distributed throughout the brain, particularly in Ammons horn, the cerebral cortex, the brainstem, the hypothalamus, the Purkinje cells of the cerebellum, and the dorsal spinal ganglia. Negri bodies are not demonstrated in at least 20 of cases of rabies, and their absence from brain material does not rule out the diagnosis.
