Compared with those in the control group (C), the DEGs in the Salmonella group (S) were enriched mainly in pathways related to the B cell receptor signalling pathway, the NF-κ B signalling pathway, the intestinal immune network for IgA production, African trypanosomiasis, drug metabolism (cytochrome P450), and asthma (Figure 5D-b). Here, CD79A is linked to human African trypanosomiasis.
