FIG. 1.

Analysis of PCV viral load (A and B) and serum ALT levels (C) following treatment with interferon alfacon-1 or ribavirin initiated 4 h prechallenge. The limit of detection for the virus titer assays was 2.8 log₁₀ CCID₅₀ per g of liver tissue (A) or ml of serum (B) and is indicated by the hatched gray lines. Values represent the means and standard deviations of groups of five animals (three for the sham-infected controls; ALT) sacrificed on the indicated days. Values were not obtained for the infected saline-treated placebo group for the day 8 time point, since there were no survivors. * indicates a P of <0.05 and ** indicates a P of <0.01 in comparison to saline-treated controls.
