Simian AIDS--evidence for a retroviral etiology.

This paper reviews the major features of a simian model of acquired immunodeficiency ('SAIDS'), SAIDS occurs endemically in colonies of macaque monkeys in the United States and resembles AIDS in humans in overall clinical manifestations, pathology, and immune deficiency. An infectious type D retrovirus, related to but distinct from the Mason-Pfizer monkey virus, has been identified as the primary cause of SAIDS. The relevance of these findings for human AIDS is discussed.

Molecular comparison of retroviruses associated with human and simian AIDS.

Infectious retrovirus(es) associated with the human (LAV, HTLV-III, ARV) and simian (SAIDS-1) acquired immune deficiency syndrome were compared by electron microscopy, immunofluorescence and immunoblotting techniques and by restriction endonuclease mapping of the viral genomes. The extracellular virus particles had similar type D morphology, but intracytoplasmic type A nucleoids were found only in SAIDS virus infected cells. Although the antigens of the three prototype AIDS viruses were similar, no cross-reactivity with the SAIDS virus was detected. Molecular hybridization and restriction enzyme analysis also revealed that the SAIDS and AIDS viruses were genetically unrelated. However, only minor differences, consistent with strain polymorphism, were found between the three AIDS virus isolates. Thus, the retroviruses associated with AIDS in macaques and humans are unique to each species.
