Figure 9 shows that compared to the control group, the gene expression of FKBP5 and S100A12 increased significantly after Salmonella infection, while the expression of EMC6, FAM168B, and HESX1 decreased significantly. The expression level of NFU1, PIGC, and USP8 decreased under Salmonella infection, without a significant difference between non-infected and ST-infected chickens (Figure 9). This evidence concerns the gene FKBP5 and Salmonella Infections.
