Abstract
In the current study, gross and histopathological investigations were carried out on a total of five camels, those died of naturally infected pneumonic pasteurellosis in desert conditions during the summer season. The humidity was very high and morbid animals showed signs of respiratory distress. History indicated that the clinically infected animals had high fever, depression, salivation, frothy nasal discharge, and respiratory sounds. At necropsy investigations, consistent lesions included submandibular edema, the presence of frothy exudate in the trachea, congested and swollen lymph nodes, congested, edematous and dark-colored kidneys, severe enteritis, pericarditis, and myocarditis. The lungs were severely congested, and consolidated and indicated frothy exudate at the time of incision in bronchi and pleural adhesions. The serosanguinous fluid was accumulated in the pericardium and peritoneal cavities. Histological examination revealed severe congestion, perivascular cuffing, and large interlobular septae perforated by inflammatory cells. The liver showed congestion, edema, and hemorrhages while the kidneys and heart showed inflammatory exudate and hemorrhages. The lymph nodes indicated degenerative changes. It was sconcluded that the deaths occurred due to pneumonic pasteurellosis caused by Pasteurella multocida in camels.
