A historical perspective: Simian AIDS-an accidental windfall
1School of Medicine, University of California, Davis, CA, USA. mbgardner@ucdavis.edu.
Background:
For the past 30 years, Simian AIDS has provided an indispensible animal model for the human disease. This historical perspective highlights the circumstances leading to the creation of this experimental model.
Methods:
Historical information and stored non-human primate (NHP) specimens, including isolates of Simian immunodeficiency virus (SIV), were analyzed by molecular epidemiologic methods to trace the lineage and transmission of SIV among NHPs at US primate centers.
Results:
The rhesus and stump-tailed macaque models of Simian AIDS are the result of the accidental transmission of SIV from healthy sooty mangabey carriers to naïve macaques during the course of human kuru experimental transmission studies at UC Davis during the 1960s.
Conclusions:
Simian AIDS, first recognized in the 1980s, is the accidental result of experimental kuru transmission experiments carried out in the 1960s, which led to the discovery of infectious prions but inadvertently transmitted SIV, unknown at that time, from sooty mangabeys to macaques.
Insights
Simian AIDS, an important model for human disease, originated from accidental Simian Immunodeficiency Virus (SIV) transmission during 1960s kuru experiments. This historical analysis traces SIV
Area of Science:
- Veterinary Pathology
- Primate Research
- Virology
Background:
- Simian AIDS has served as a critical animal model for human immunodeficiency for three decades.
- This historical review details the origins and establishment of this experimental model.
Observation:
- Molecular epidemiologic methods were employed to analyze historical data and non-human primate (NHP) specimens.
- The study traced the lineage and transmission patterns of Simian Immunodeficiency Virus (SIV) among NHPs in US primate centers.
Findings:
- Simian AIDS arose from the accidental transmission of SIV from sooty mangabeys to macaques.
- This transmission occurred during 1960s kuru experiments at UC Davis, affecting rhesus and stump-tailed macaques.
Implications:
- Understanding the inadvertent transmission of SIV highlights the importance of biosafety in research.
- The historical context of Simian AIDS provides valuable insights into viral evolution and disease emergence in primate models.
