† TD/96 and 94.4 indicate the TD/96/TWN and 94.4/IL/94/TWN strains, respectively. * Values with different superscript letters, a-c, among the three groups of samples at the same dpi indicate a statistically significant difference (p < 0.05) from each other. The superscript letter “a” indicates the highest viral load and “c” indicates the lowest viral load among the compared groups. ¶ The pig was euthanized at the end of the experiment. § ND: not detected.
