Transmission of the simian immunodeficiency virus SIVmne in macaques and baboons.

ABSTRACT

A primate lymphotropic lentivirus was isolated on Hut 78 cells after cocultivation of a lymph node from a macaque that died with malignant lymphoma. In earlier studies SIV/Mne was inoculated into 17 macaques and two baboons. All of the macaques became viremic and seropositive. Fifteen of the macaques succumbed to a classic AIDS-like disease, whereas the baboons did not become viremic. The SIV/Mne virus has now been molecularly cloned and inoculated into Macaca nemestrina and baboons. A new transmission study has been initiated to test the effects of route and dosage on disease.
