Weekly change in the body weight of 5-week-old pigs after porcine epidemic diarrhea virus strain Pintung 52 (PEDVPT)-P5 or PT-P96 inoculation. The weekly differences in mean body weight for each group are shown as mean ± standard error of the mean (SEM). The black, gray, and dashed lines illustrate the values obtained for the PEDVPT-P96-inoculated group, PEDVPT-P5-inoculated group, and mock-infected group, respectively. The arrow indicates the time point when the pigs were challenged with the low passage PEDVPT-P5 (27 DPI or 0 DPC) strain. P5: low passage virus, PEDVPT-P5; P96: high passage virus, PEDVPT-P96; mock: PI medium control; DPC: days post-challenge.
