Polio encephalitis Due to Poliomyelitis Virus

Abstract

The case of fatal polio-encephalitis described in detail below is reported because of its interesting clinical picture and because of the striking proof of the diagnosis by intra- cerebral inoculation in a monkey. The similarity of the lesions in the cord of the human victim to those in the monkey inoculated with a filtered saline extract from the child's brain and cord can easily be seen by reference to the illustrations.
