Figure 2

Changes in Th1 cytokine expression in the bursa tissues of chickens infected with either H or Ts strain. Changes in IFN-γ, IL-2 and IL-12p40 mRNA expression were quantified by real-time PCR and expressed as the fold-change in birds infected with either H or Ts strain of IBDV, when compared with uninfected birds. Bars show the means and standard errors (SE) from three separate experiments. The difference in cytokine expression between experimental and control was assessed by student's t-test and comparisons were considered significantly different at P ≤ 0.05 (*) and at P < 0.01 (**). dpi: days past-infection.
