Course of IL4I1 mRNA expression in the chicken cecum afterSEnteritidis infection determined by real-time PCR. Chickens were infected at the day of hatch, sacrificed at time points as indicated and expression of IL4I1 was determined by reverse transcribed real time PCR. On days 3, 6, 9, 10 and 29, absolute Ct values for IL4I1 were below a value 30 in 2 out 4 tested non-infected chickens, and on days 11 and 12 absolute Ct values for IL4I1 were below 30 in 1 out 4 non-infected chickens indicating low IL4I expression in the cecum in the absence of infection. Asterisks—statistically significant differences from non-infected chickens (Mann–Whitney U test, P ≤ 0.05).
