FIG. 7.
Dynamics of serum VL in SIVsm-infected BkMs. Due to the sampling schedule, the peak VL could not be measured, and dashed lines covering the interval of days 0 to 30 p.i. are used to reflect this uncertainty. During the follow-up, the VL in BkMG138 (•) showed a significant increase (>1 log) with the progression to AIDS. In contrast, in BkMG139 (▪) and BkMG140 (▴), a tendency to clear viral infection was observed. VL was measured by a bDNA assay (detection limit, 125 eq/ml).
