[Virological study of simian hemorrhagic fever].

The results of a comparative study of different routes of inoculation of simian hemorrhagic fever (SHF) virus to Macaca monkeys are presented as well as the results of virological examinations of sick animals. Only the parenteral route of inoculation has been found to be effective. After virus penetration, a long-term viremia and generalization of the infection are observed. The virus is found in the brain, the spinal cord and bone marrow, the spleen, the liver, the kidneys, the cerebrospinal fluid, the urine and nasopharyngeal washings. By the fluorescent antibody technique the virus-specific antigen is demonstrated in the capillary endothelium, neurons and glial cells of the brain, and in the reticulo-endothelial and macrophagal elements of parenchymatous organs.
