Panel showing hematoxylin eosin stained tissues from IC89-infeced goats without histological abnormalities (left) and PPRV MA08-infected goats (right) for comparison. A Retropharyngeal lymph node, goat number 9. Unremarkable. B Retropharyngeal lymph node, goat number 13. There is moderate depletion of lymphocytes and lymphoid follicles are multifocally poorly distinct or absent. C Ileum, goat number 8. Unremarkable. D Ileum, goat number 14. There is a moderate depletion in the Peyer’s patches. E Lung, goat number 9. Unremarkable. F Lung, goat number 13. The parenchyma is diffusely effaced by a bronchointerstitial pneumonia and a concomitant suppurative bronchopneumonia. There are abundant perivascular and peribronchiolar lymphocytes with hyperplasia of the bronchiolar epithelium (arrows) as well as neutrophils within bronchiolar and alveolar lumens. Inset: There is a prominent hyperplasia and hypertrophy of pneumocytes type 2 (arrow). Alveolar lumens contain moderate numbers of neutrophils and fewer macrophages.
