Incidental findings of pathological significance in pneumonic lungs of sheep in Al Qassim Area, Kingdom of Saudi Arabia: an abattoir survey

Abstract A total of 1425 ovine lungs were grossly examined at the local abattoir during a 6-month survey on the aetiology and pathology of pneumonia in slaughtered sheep at the Al-Qassim region, Kingdom of Saudi Arabia. The results of the survey demonstrated the occurrence of several types of pneumonic and related lesions in 140 specimens of condemned lungs. However, more detailed microscopic examination of the pneumonic lungs incidentally revealed the coexistence of some other significant pathological alterations indicative of sheep pulmonary adenomatosis (Jaagziekte), ovine syncytial virus infection, ovine progressive pneumonia (maedi) and verminous pneumonia. In addition, pulmonary corpora amylacea (PCA) were also detected in the bronchial lumen of some pneumonic lungs initially diagnosed as fibrinous pneumonia. It is worth mentioning that none of the abovementioned cases was previously recognized or diagnosed in the Al-Qassim region or in any other parts of the Saudi Kingdom.
