Ultrasonographic evaluation of cattle and buffaloes with respiratory disorders.
The purpose of the present study was to evaluate cattle and buffaloes with respiratory disorders, determine the extent of the lesions, and assess prognosis. The results were compared with the findings determined following physical examination and at slaughter. Animals were referred to Veterinary Teaching Hospitals because of inappetance, loss of body condition, cough, dyspnea, and nasal discharges. Ultrasonographically, it was possible to detect bronchopneumonia, consolidation, pleural effusion, pulmonary emphysema, and pleuritis. It was not possible to visualize lesions located deeper within the lungs where peripheral tissue was not affected. Laboratory findings included a neutrophilic leukocytosis, γ-globulinemia, and increased activity of aspartate aminotransferase. A diagnosis of respiratory disease was made on the basis of clinical and ultrasonographic findings and confirmed in 25 cases at slaughter. Bovine ultrasonography appears to be suitable as a screening tool for detection of pathologic lung processes near the pleura. Thoracic ultrasonography allows assessment of the extent and severity of pulmonary changes so that further evaluations can be considered.
