ABCG2 and staphylococcus aureus infection: KEGG analysis revealed 20 KEGG pathways, among which, ABC transporters (ko02010) and ribosome (ko03010) pathways were the most enriched pathways in the DEGs, and other major pathways included quorum sensing (ko02024), Staphylococcus aureus infection (ko05150), valine, leucine and isoleucine biosynthesis (ko00290), pyrimidine metabolism (ko00240), and purine metabolism (ko00230), indicating that these pathways played significant roles in antibacterial processes of FCS.
