  1. a Monkeys were infected intravenously with 10 AID50 of the non-pathogenic nef-deleted SIVmac251 isolate (SIVΔnef) or the pathogenic strain SIVmac251 (SIV+) and were studied 8 months later.
  2. Values are means ± SEM.
  3. b PMN, lymphocytes, CD4+ and CD8+ counts are expressed per microliter.
  4. c Viral load is expressed as 102 copies per milliliter.
  5. d Significantly different from healthy controls (SIV-) (p < 0.05).
  6. e Significantly different from SIVΔnef (p < 0.05).
  7. f Significantly different from SIV+ slow progressors (p < 0.05).
