    Abstract:
    Four rhesus monkeys (Macaca mulatta) were inoculated with a homogenate of a cutaneous lepromatous leprosy lesion from a mangabey monkey (Cercocebus atys). One died of B-cell lymphoma, and another died of an immunodeficiency syndrome. Cell suspensions prepared from the tumor and spleen of the monkey with lymphoma induced lymphoma or an immunodeficiency syndrome when inoculated into additional young rhesus monkeys. The immunodeficiency syndrome was similar to simian acquired immunodeficiency syndrome and consisted of opportunistic infections, lymphoid hyperplasia or atrophy, wasting, and syncytial cell formation. Mitogen responses and percentages of T4- and T8-positive lymphocytes were normal until the animals were moribund. Lymphoblastoid cell lines became established in vitro from tumor cell suspensions. These cells were infected with a herpesvirus related to Epstein-Barr virus. In addition, a retrovirus morphologically similar to human T-cell lymphotrophic virus type III (HTLV-III) and simian T-lymphotrophic virus type III (STLV-III) was isolated from one of the lymphoblastoid cell lines (LCL). Type D retroviruses could not be demonstrated in the monkeys in the transmission study; however, a retrovirus similar to that in the LCL was isolated from 4 animals by coculture of peripheral blood lymphocytes with the human cell line H9. These results suggest that this retrovirus, STLV-III/Delta, may be associated with the immunodeficiency syndrome in these macaques and may be of mangabey origin.
