a
Number of positive pigs/number of pigs tested.
b
Number of PGAR-positive pigs by RT-PCR. For the PEDV/PGAR group, PEDV was infected orally 12 h after inoculation with PGAR.
c
Number of PGAR-positive pigs by virus isolation. For the PEDV/PGAR group, PEDV was infected orally 12 h after inoculation with PGAR.
