Venn diagram showing the number of differentially expressed genes overlapped in different comparisons. CF4ab: IPEC-J2 cells infected with F4ab ETEC; CF4ac: IPEC-J2 cells infected with F4ac ETEC; CF18ac: IPEC-J2 cells infected with F18ac ETEC; Control: the non-infected IPEC-J2 cells. A (Total): number of genes overlapped among the three comparisons of CF4abvs control, CF4acvs control and CF18acvs control; B (+) and C (−): number of up-regulated/ down-regulated genes overlapped among the above three comparisons respectively; D (Immune-related genes): number of differentially expressed immune-related genes overlapped among the three comparisons.
