Evidence for a lentiviral etiology in an epizootic of immune deficiency and lymphoma in stump-tailed macaques (Macaca arctoides)

J Med Primatol. 1992 Jan;21(1):1-14.

Abstract

A retrospective study determined that an epizootic of immune suppression and lymphoma in stump-tailed macaques (Macaca arctoides) that began in 1976 was associated with a horizontally spread lentivirus infection. This conclusion was based on serology, epidemiology, pathology, and virus isolation. The lesions found in the stump-tailed macaques were more compatible with lesions seen in SIV-infected rhesus than those seen in rhesus macaques infected with type D retroviruses. A lentivirus, isolated from a rhesus inoculated with lymph node homogenate from a stump-tailed macaque, was designed SIVstm and was pathogenic for rhesus macaques. The isolate was antigenically related to other SIVs as well as to HIV-1 and HIV-2. Two surviving stump-tailed macaques sent to another colony carried SIVstm latently for at least 7 years and disseminated it throughout that colony.
