Hematoxylin and eosin–stained tissue samples from colobus 1 in an investigation of novel mastadenovirus infection causing pneumonia in imported black-and-white colobuses (Colobus guereza), Thailand. A) Trachea showing mucosa is extensively replaced by laminated bands of fibrillar material (arrows) intermixed with aggregates of karyorrhectic debris and degenerated neutrophils. B) Lung section showing lumen of the bronchial airways; flocculent mats of fibrin (asterisk) and neutrophils can be seen. C) Lung section showing alveoli filled with foamy macrophages (arrows), polymorphonuclear cells and eosinophilic material (arrowhead); alveolar capillaries are markedly engorged. Scale bars indicate 100 µm.
