An investigation was carried out to study the pathology of spontaneous capripox virus infection amongst sheep and goat in Jammu region through clinical survey and confirmatory laboratory diagnosis. Clinically, the disease exhibited an acute febrile phase and a less severe but prolonged phase. Cutaneous lesions were visible during the febrile phase progressing through erythematous maculo-papular stages and formation of nodules. Healing was typified by ulceration and characteristic pock lesions over sparsely haired/wooled areas of the head and other body parts. Systemic lesions included circumscribed necrotic areas on the liver surface, circular grayish-white plaques in the mucosa of the abomasum along with mild catarrhal enteritis and white necrotic foci on the kidney. In the respiratory system, a consistent finding was the presence of multifocal pneumonia and grayish-white papules, nodules or plaques throughout the lung surface. Histopathologic alterations of skin were marked along with presence of eosinophilic intracytoplasmic inclusion bodies the spinous cells. Surface lesions of lung tissue were characterized by noticeable pleuritis and massive fibrosis. Bronchial hyperplasia and bronchiolar epithelium metaplasia into rounded cells was observed. Alveolar changes were marked by alveolitis and metaplasia of lining epithelium to type II pneumocytes. Intracytoplasmic eosinophilic inclusions could be seen in bronchiolar epithelium and other cells in the alveolar areas. Surface lesions on the liver corresponded with focal degeneration and necrosis of hepatocytes along with demonstrable eosinophilic intracytoplasmic inclusion bodies in biliary epithelium. Mucosal lesions in the abomasum were characterized by vacuolar endothelial degeneration and thrombosis of serosal blood vessels. Intestinal sections revealed atrophy of villi and inflammatory cells in the submucosa. Changes in the kidneys were typified by membrano-proliferative glomerulonephritis, while lymphoid depletion and cystic cavitation of follicles were noticed in the spleen and lymph nodes.
