FIG. 4.
Effect of lymphocyte depletion on viremia. The viral genome was detected by rRT-PCR in serum samples collected from day 0 to 7 and day 9 postinfection. Genome copies per ml serum are displayed for anti-CD4 MAb treated-animals (a) and TRT3 control MAb-treated animals (b) from both experiments and for anti-WC1 MAb-treated (c) and anti-CD8 MAb-treated (d) animals from experiment 1.
