PEDV-shedding detected via RT-qPCR: The graph shows the amount of genome copies per group using a logarithmic scale with 1e + 8 meaning 108; red lines mark the mean (average) of each box plot, black lines mark the median of each box plot; upper chart: Group A1 and A2 (cell culture isolate; PEDV EU), lower chart: B1 and B2 (German field material, DE); statistically significant differences between groups with and without maternal derived antibodies (compared by day) are marked with **(p-values between 0.001 and 0.034). To indicate the number of samples included in each boxplot, the survival curve is given above the respective figure part.
