Histopathological study of lung tissues in sick dogs. Representative images of hematoxylin and eosin stained necropsy samples are shown. A Sample showing moderate vasculitis with rich-protein alveolar oedema and haemorrhages. B Lung tissue showing alveolar lined by type II pneumocytes and inflammatory infiltrate in the alveolar lumens. C Arteriolar wall hyalinosis is shown. D Diffuse alveolar damage with oedema and intra-alveolar hyaline membranes are shown. Scale bar: 200 µm (A, D) and 50 µm (B, C).
