[The CNS lesion in monkeys spinally infected with the vaccinal poliomyelitis virus]

Specific features of the CNS lesions in monkeys inoculated with a vaccine poliovirus strain were studied in comparison with those developing after inoculation with virulent strains. The lesions in the lumbar cord and other regions of the brain and spinal cord after intraspinal inoculation of the vaccine virus are described at length. Certain signs reflecting the specific nature of the lesions were observed. The results of histopathological and immunofluorescent studies were shown to be important for differentiation of specific and nonspecific lesions.
