Additional file 6 of Host genetics, lung T-cell immunity, and laying activity determine the disease outcome in avian influenza virus-infected chickens

Additional file 6. Raw data tables pathology. Raw data for hematoxylin and eosin staining (A), the score defines as follows: 0 = no lesion; 1 = rare (< 5%), 1–3 foci, minimal; 2 = multifocal (6%–40%), > 3 foci, mild; 3 = coalescing (41%–80%), moderate; 4 = diffuse (> 80%), severe; ‘–‘ = not present on slide. Raw data for immunohistochemistry, the score defines as follows: 0 = no antigen; 1 = focal / oligofocal (< 5%), 1–3 foci; 2 = multifocal (6%–40%), > 3 foci; 4 = coalescing (41%–80%); 5 = diffuse (> 80%). ALT: Altsteirer, BIE: Bielefelder, RAM: Ramelsloher, BALT: bronchus-associated lymphoid tissue, PALS: periarteriolar lymphocyte sheaths (mainly T lymphocytes), PELS periellipsoid lymphocyte sheaths (mainly B-lymphocytes).
