Lung infections are major findings in domestic animals. Outbreaks occur in camels, cattle, buffaloes and small ruminants in various countries. Forty lungs of one-humped camels (6 months to 10 years old) slaughtered at different abattoir in Egypt were grossly examined for the presence of pneumonic lesions. Specimens, collected from gross lesions were subjected for histopathological and bacteriological investigations. The main pathological lesions of affected lungs were bronchitis,  bronchiolitis, alveolar emphysema, inflammatory and non-inflammatory edema, active hyperemia, interstitial pneumonia, lung granuloma, suppurative pneumonia and haemorrhagic pneumonia.. Bacteriological investigation resulted in the recovery of 89 bacterial isolates. This work aimed to isolate the most common bacterial pathogens    causing    respiratory affections     from     slaughtered     camels. A second goal was to describe the pathological changes in the lungs of affected camels and to correlate these changes with the possible causative agents.
