Immunohistochemical detection of viral antigen and immunostaining assessment of lungs (A), spleens (B) and brains (C) of mice infected with r-06 and r-06/NA2 at 6 dpi. Arrows indicate antigen staining. All the images are shown at 400× magnification. In the lung and spleen, scores (0–9) were assigned based on the percentage of positive staining and intensities of the signals. In the brain, the percentage of the positively stained cells was calculated *P < 0.05.
