Figure 3. The rectal temperatures and the mortality of piglets inoculated with the rescued virus with the exchanged coding regions.

Body temperatures of piglets inoculated with rescued viruses with the RvJXwn backbone (A) and with the RvHB-1/3.9 backbone (B). Body temperatures are shown as the means ± standard deviations (error bars), except the number of survival piglets in each group was less than two. The survival curves (C) and mortalities (D) of infected piglets in each group (n = 5) are shown.
