Figure 9From: Vpx is Critical for SIVmne infection of pigtail macaquesEffect of Vpx mutations on SIV replication in pigtail macaques. A) The design of the macaque infection shows that animals were inoculated by intra-rectal challenge, and one of two animals were sacrificed at 21 days after infection (✝), and the second animal in each group at 42 days after infection. Time points at which blood samples were obtained are also indicated. B) Plasma levels of SIV RNA (copies/ml) are indicated on a log scale for each of the 8 animals. The limit of detection in this assay was 50 copies/ml.Back to article page
