Cytokine gene expression: (A) Cecal tonsils of birds; (B) Bursa of Fabricius; (C) Spleen. Each bar represents the mean ± SEM of fold change in gene expression from 9–11 birds per treatment group. The P-values between groups were determined by one-way ANOVA followed by Tukey's multiple comparisons post-hoc test. Only significant comparisons are indicated in the figures.
