Figure 6.

Frequency of activated immune cells in the splenocytes of birds: (A) B-cells; (B) T-helper cells; (C) Cytotoxic T cells. Cells isolated at DPC4 and DPC10 were restimulated with OMP+FLA for 48 hr and then subjected to flow cytometry analysis. Each bar represents the mean ± SEM from 6 birds per 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.
