dpi = days postinoculation; kDa = kilodalton.

^*Urine samples from the noninoculated pig (negative control) were negative at all time points of urine collection.

^†Urine samples collected before infection were negative.

^‡The presence of any of the bands of 75, 80, 120, and 150 kDa was considered to give a positive result.
