A rare case of cardiovascular disease in a Boer goat revealed severe aortic dissection and neurolisteriosis. This study details the pathological findings in a goat presenting with neurological signs and hyperthermia.
Area of Science:
- Veterinary Pathology
- Cardiovascular Diseases in Ruminants
- Infectious Diseases in Goats
Background:
- Primary cardiovascular diseases are infrequently reported in goats.
- Common conditions include septal defects, endocarditis, pericarditis, poisoning, and cardiomyopathies.
Purpose of the Study:
- To report the pathological findings of a Boer goat with neurological signs and hyperthermia.
- To identify the causative agents of the observed pathology.
Main Methods:
- Necropsy and histopathological examination of a deceased Boer goat.
- Bacterial culture of affected aortic tissue.
- Histopathological assessment of central nervous system lesions.
Main Results:
- Severe aortic dissection with thrombosis and stenosis, pulmonary congestion, and edema were observed.
- Histology revealed chronic granulomatous and fibrosing dissecting aortitis with mineralization.
- Pasteurella multocida and Staphylococcus spp. were isolated from the aorta; CNS lesions indicated neurolisteriosis.
Conclusions:
- This case highlights a rare presentation of severe aortic dissection in a goat.
- Concurrent neurolisteriosis suggests a complex etiology involving bacterial infection and cardiovascular compromise.
