T. gondii organisms and immunohistochemical staining with an anti-T. gondii antibody. a Liver, pig E in the DS-L group. Slightly basophilic oval organisms (arrows) in the cytoplasm of hepatocytes were stained with hematoxylin and eosin. b Necrotic liver foci, pig E in the DS-L group. Positive reactions, stained brown, are scattered within the necrotic foci; non-affected parenchyma can be seen around the foci, as detected by immunohistochemical staining. c Lung, pig E in the DS-L group. Positive reactions were scattered throughout the thickened alveolar wall, as detected by immunohistochemical staining. Bar in a) represents 20 μm and bars in b) and c) represent 50 μm
