Corticosterone administration modulated relative mRNA gene quantities of immune cytokine genes in the spleen and thymus. Birds were administered 0.2% ethanol drinking water (Cp−St−), challenged with 107 CFU C. perfringens (Cp+St−), administered 20 mg/L CORT (Cp−St+), or received both C. perfringens and CORT challenge (Cp+St+). Treatments commenced in birds at 14-days-of-age, where C. perfringens was administered for 2 days and CORT for 7 days. (A-B) Relative mRNA quantities in the (A) spleen and (B) thymus. Vertical lines associated with histogram bars represent standard error of the means (n = 4). Asterisks indicate significant differences (P < 0.050)
