Relative RNA expression of innate immune genes in chicken (Ck) and Japanese quail (JQ). The fold change was calculated relative to levels of mRNA expression in infected birds compared to sham birds. Data plotted in green represents down-regulation (significantly lower than shams). Blue (*) shows significant differences between clinical stages ● asymptomatic, ■ listless, and ▲ moribund/dead. Significance p < 0.05.
