Viral loads in different organs of chickens challenged with virulent FAdV-4 and FAdV-8b. Viral loads in the different tissue samples were quantified by a standard curve quantitative real-time PCR method. A The viral loads in different tissues of chickens in the FAdV-4 challenge group. B The viral loads in different tissues of chickens in the FAdV-8b challenge group. In general, the viral loads in the vaccinated group and uninfected control group were significantly lower than the unvaccinated group for both viral challenge groups (*p-value < 0.05, **p-value < 0.01, ***p-value < 0.001).
