Figure 3. Measurement of SIV RNA in serially sacrificed RMs infected with SIVagm.sab.
Six rhesus macaques were included in this study and were serially sacrificed at the peak of viral replication (day 9 pi-RMDJ52 and D10 pi-RMCV08), at the set-point (day 35 pi-RMDJ73 and D42 pi-RMEK15) and during chronic infection (D180pi), when infection is controlled (RMCM48 and RMCE26). (a) Quantification of plasma viral load showed that all these RMs replicated the virus at high levels during acute infection and that the virus load was controlled below detection limits in the RMs euthanized during chronic infection. (b) Quantitative RT–PCR analysis of SIVagm.sab RNA from over 30 tissues obtained at necropsy demonstrated that virus control is not due to a restriction of virus replication to a limited number of anatomical sites.
