To develop a model of SHIV-KB9/Chinese origin rhesus (Ch Rh) macaques for vaccine research and to compare the pathogenesis of SHIV-KB9 in Ch Rh macaques with that reported in Indian rhesus (had Rh) macaques. Methods Seven mamu-A*01 negative Ch Rh macaques were inoculated intravenously with 1-10000 MID of SHIV-KB9. The monkeys were monitored for viral load, CD4, CD8, SHIV-specific antibody and virus genetic variation. The results were compared with those previously observed in Ind Rh macaques. Results As compared to that observed in Ind Rh macaques, SHIV-KB9 in Ch Rh macaques displayed three identical disease progression patterns. However, the primary pattern was not identical between the two subspecies. The level of plasma viremia differed in SHIV-KB9-infected Ch Rh macaques which exhibited different outcomes from those in Ind Rh macaques. Generally, the values of viral load and the maintenance of CD4T cells profoundly depleted. Conclusion The model of SHIV-KB9/Ch Rh macaques displays a relatively slow progression to AIDS compared with Ind Rh macaques, which may more accurately reflect the potential ofcandidate vaccines in humans.
