Fig. 4.

Virus shedding in rectal swabs (A), sera (B) and various tissues (C) of PDCoV-inoculated pigs. Data labels (fractions) represent the number of PDCoV PCR positive pigs out of all pigs examined at that time point. The Ct values depicted in each figure were mean Ct values of PCR-positive pigs. The virus titers (Log₁₀TCID₅₀/ml) were mean virus titers of all pigs (both PCR-positive and negative pigs). Standard error bars are shown in each figure. At 3 DPI, sera were successfully collected from 8 out of 10 pigs.
