FIG. 3.

Comparison of clinical scores (A) and survival rates (B) of PG-1 transgenic (TG) mice and their WT littermates after intranasal inoculation of A. suis. The day of inoculation is indicated as day 0. Data represent the means ± SEMs of six independent experiments (transgenic mice, n = 68; WT mice, n = 58). Asterisks indicate a significant difference between the two groups for each day at significance levels of P < 0.05 (*) and P < 0.01 (**). Different superscripts indicate significant differences between the mean clinical scores within the transgenic group during the 6-day experiment (P < 0.05). The mean clinical scores within the WT group were not significant different (P > 0.05).
