Experimental induction of simian acquired immune deficiency syndrome (SAIDS) by inoculation of juvenile rhesus monkeys with a type D retrovirus was prevented by immunization with Formalin-killed whole SAIDS retrovirus serotype 1 containing the adjuvant threonyl muramyl-dipeptide. All six immunized animals developed neutralizing antibody after three injections, while six age-matched cagemates receiving adjuvant alone were antibody free. All 12 monkeys were challenged intravenously with a potentially lethal dose of SAIDS retrovirus serotype 1. The six immunized animals failed to develop persistent viremia and remained clinically normal 8 months postchallenge. In contrast, five of six nonvaccinates developed persistent viremia, four of six developed clinical SAIDS, and two of six died with SAIDS at 10 weeks and 8 months postchallenge, respectively. These results show that prevention of a common spontaneous retrovirus-induced immunosuppressive disease in macaques is now possible by vaccination.

D009500 Neutralization Tests The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).

D000163 Acquired Immunodeficiency Syndrome An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.

D012190 Retroviridae Family of RNA viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).
