Survey on Histopathologic Patterns of Pulmonary Lesions in Slaughtered Camels (Camelus deromedarius) in Qom, Iran

Pulmonary diseases in camelids represent one of the major complaints in camelidveterinary practice. The present study was undertaken during autum and winter 2012 toinvestigate histopathologic patterns of pulmonary lesions in camels (Camelusderomedarius) slaughtered in Qom slaughterhouse. In this study, 46 out of 100 carcasesinspected randomly at postmortem, found with one or more pulmonary lesions. Propertissue samples obtained from lungs with macroscopic lesions, fixed in 10% neutral bufferformaldehyde, processed for routin histopathological techniques, and finally sections of5μm thickness cut and stained by H&E staining techniques. The major pulmonary lesionsencountered on camel lungs were as follow: interstitial pneumonia, 31 (67/39%);fibrinous bronchopneumonia, 19 (41.3%), purulent bronchopneumonia,21(45/65%);pneumoconiosis, 15 (32.60%); hydatidosis 3 (6.52%); verminus pneumonia 2 (4.34%);calcified cyst 4 (8.89%); atelectasis 8 (17.39%); pulmonary emphysema 18 (39.13%).Asthe results indicate, the interstitial pneumonia was considered as the most commonpulmonary lesion in camels and was the major factor of condemnation (67/39%) of lungsin this species in this Qom slaughterhouse.
