Mean histopathological lesion scores ± SE for quails inoculated with pH1N1, swH1N1, or dkH3N2 as well as the corresponding contact birds

^*No lesions were observed in the brain, heart, spleen, liver, pancreas, or kidney. ^†Mean histopathological lesion scores ± SE obtained by combining individual scores from all sampling days (3, 5, and 7 DPI). Scoring was based on the degree of inflammation in the lesions: 0 = no lesions detected, 1 = mild, 2 = moderate, and 3 = severe. Mean values with different superscript letters (a, b, and c) within the columns are statistically different (p < 0.05).
