Pulmonary diseases in camelids represent one of the major complaints in camelid veterinary practice. The present study was undertaken during spring 2010 to investigate histopathologic patterns of pulmonary lesions in camels (Camelus deromedarius) slaughtered in Semnan slaughterhouse. In this study, 33 out of 100 carcases (totally 150 carcases) inspected randomly at postmortem, found with pulmonary lesions. Proper tissue samples obtained from lungs with macroscopic lesions, fixed in 10% neutral buffer formaldehyde, processed for routin histopathological techniques, and finally sections of 5µm thickness cut and stained by H&E staining techniques.
The major pulmonary lesions encountered on camel lungs were as follow: interstitial pneumonia 30 (90.9%), pulmonary fibrosis 15 (45.45%), pneumoconiosis 24 (27.72%), atelectasis 27 (81.81%), pulmonary emphysema 24 (27.72%), hydatidosis 12 (36.63%), calcified cyst 12 (36.63%), bronchopneumonia 18 (54.54%), parasitic pneumonia 1 (9.09%).
