Figure 5

Messenger RNA (mRNA) expression of interferon regulatory factor 7 (IRF7) on the intestinal mucosa of neonatal pigs. The mRNA levels were determined using qPCR. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and beta-actin were used as an internal control to normalize changes in specific gene expressions. The results were presented as fold changes relative to the control animals. Different lower-case letters indicate significant differences between each group and each day post inoculation (DPI) (p < 0.05).
