The changes in the numbers of CD4+ T lymphocyte in peripheral blood,plasma viral loads,proviral DNA and humoral antibodies against virus were periodically monitored during 121 days. At the early stage of infection,proviral DNA had been detected in PBMCs,and infectious SIVmac239 virus had been isolated from PBMCs. At the same period,the numbers of CD4+ T lymphocytes were significantly decreased,and maintained at low level during the 121-day period of infection. Plasma viral loads reached the peak at week 2 post-inoculation and kept at a steady state subsequently. Moreover,antibodies against viral proteins were detected from plasma. All the results showed that the two Chinese rhesus monkeys had been infected with SIVmac239 successfully. This animal model can be applied for further AIDS researches.展开更多
