Figure 1From: Deterioration of eggshell quality in laying hens experimentally infected with H9N2 avian influenza virus Viral loads in the oviducts of H9N2 subtype avian influenza virus (AIV) infected laying hens. Kinetics of virus load of H9N2 subtype AIV in the oviducts of laying hens infected with H9N2 subtype AIV strain using quantitative real-time PCR. Each time point represents the mean viral genome copies per 0.1 g of tissues ±SEM obtained from five hens.Back to article page
