Virus level in the blood and tissues of the infected rabbits. Copies of HTLV-1 viral DNA per million of mononuclear cells in the blood of all infected animals overtime expresses as average (A) or presented for each animal at the time of killing in the appendix (B) and jejunum (C). The horizontal bars represent the average values. The statistical analysis of the data in blood was performed with the repeated measures of variance of the log-transformed copy numbers, and the P values for pairwise differences at each week were corrected by the Hochberg method.
