SHIV replication in macaques exposed to a pool of 16 SHIVenv_B viruses or just SHIVenv_B3. a The SHIVenv_B pool harboring 16 chimeric viruses were intravenously injected into two macaques of Indian origin. Infection of the two macaques was monitored by collecting plasma samples for 62 days and measuring viral RNA levels by quantitative real time RT-PCR for SIV Gag (Duke Human Vaccine Institute). Results are only shown for animal m328-08 in which SHIVenv infection was established. b The SHIVenv_B3 was used to infect three other rhesus macaques of Indian origin. Viral RNA was monitored for 140 days
