    Sheep pox is a highly contagious disease of sheep caused by sheep pox virus. In the present study, 3698 lungs were collected from slaughtered sheep in and around Tirupati, AP, India and examined morphologically. 396 lungs were showed different pneumonic lesions. Among 396 lung lesions, 04 (1.01%) were diagnosed as sheep pox. Grossly, the lungs revealed small to pea sized consolidated greyish white nodules visible from the lung surface. Adjacent to these lesions were congested and odematous. Histopathologically, pulmonary lesions consisted of hyperplastic or degenerative changes with mononuclear cells, neutrophils, typically sheep pox cells (SPC’s), which had vacuolated nucleus and marginated chromatin with occasional granular intra cytoplasmic inclusions. The nodules of lobular tissue revealed coagulative necrosis and serous exudates in alveolar paces. The adjacent lung tissue was variably congested and infiltrated with lymphocytes, neutrophils and macrophages. In two cases bronchi and bronchioles revealed desquamation of epithelial cells with various inflammatory cells. Based on above gross and histopathological lesions it was confirmed as sheep pox.
