Brucella suis biotype 1 infection in a dog
Journal of the American Veterinary Medical Association
|September 15, 1986
Summary
Brucella suis biotype 1 was identified in a dog exhibiting hindlimb weakness and epididymal issues. This case highlights the bacterium
Area of Science:
- Veterinary Microbiology
- Canine Infectious Diseases
Background:
- Brucellosis is a zoonotic disease caused by Brucella species.
- Canine brucellosis, typically caused by Brucella canis, affects dogs and can impact reproduction.
Observation:
- A dog presented with hindlimb weakness, a swollen epididymis, and abnormal semen analysis.
- Initial serological tests for Brucella abortus and Brucella canis were positive.
Findings:
- Brucella suis biotype 1 was isolated from the dog's semen, epididymis, and prostate gland.
- Conflicting results were observed with different Brucella serological tests.
- Necropsy revealed chronic granulomatous inflammation in the reproductive organs.
Implications:
- This case suggests Brucella suis biotype 1 can cause clinical signs in dogs, mimicking Brucella canis infections.
- Accurate diagnosis may require a combination of microbiological culture and advanced serological testing.
- Understanding the spectrum of Brucella species affecting dogs is crucial for public health and animal welfare.
