Figure 3. Significant differences between the two reciprocal F1 crosses (“129/Sv×SJL/J” vs. “SJL/J×129/Sv”).

Significant differences appeared over the whole period of observation post-inoculation for (a) the body weight (BW) (p<0.001), (b) the expiratory time (TE) (p<0.05) and (c) the minute ventilation (MV) (p<0.001). Means ± SEM are represented.
