Temporal expression acquired by comparing post- to pre-challenged chickens in Medicated and Non-medicated groups. Microarray expression data represented as fold changes by comparing each time point (D1 PI [D1], D2 PI [D2], D4 PI [D4]) in a ratio to D0 PI (D0), indicated for both Medicated (open squares) and Non-medicated (shaded squares) treatment groups. Expression data were determined by mixed model analysis of mean signal intensity minus median background intensity acquired from the Agilent 44 K chicken microarray (p < 0.001).
