Pulmonary tuberculosis in a sulfur-crested cockatoo
Journal of the American Veterinary Medical Association
|November 1, 1976
Summary
Avian tuberculosis was diagnosed in a sulfur-crested cockatoo presenting with respiratory distress and bloody discharge. Mycobacterium avium was identified as the causative agent of this pulmonary infection.
Area of Science:
- Veterinary Medicine
- Avian Pathology
- Microbiology
Background:
- Sulfur-crested cockatoos (Cacatua galerita) are susceptible to various respiratory diseases.
- Tuberculosis is a significant infectious disease affecting avian species worldwide.
- Early diagnosis and identification of the causative agent are crucial for effective management.
Observation:
- A female sulfur-crested cockatoo exhibited dyspnea and hemoptysis.
- Radiographic imaging revealed a large cystic pulmonary mass.
- Aspiration of the mass yielded thick, sanguineous fluid.
Findings:
- Ziehl-Neelsen staining of aspirate smears identified numerous acid-fast organisms.
- Gross necropsy and histopathology confirmed pulmonary tuberculosis.
- Bacteriological culture and typing identified Mycobacterium avium as the specific etiologic agent.
Implications:
- This case highlights Mycobacterium avium as a cause of tuberculosis in sulfur-crested cockatoos.
- Accurate diagnosis relies on a combination of clinical signs, imaging, cytology, and bacteriology.
- Understanding the causative agents of avian tuberculosis aids in disease prevention and control strategies.
