Description
Canine brucellosis is caused by the intracellular gram negative bacteria B. canis.
Signalment
The prevalence of brucellosis is relatively low (1-8% in the U.S); areas affceted include the U.S, Japan, South America, Spain, Tunisia and Germany. The disease is more common in stray animals and breeding kennels. There is no breed susceptibility reported but beagles are over represented in cases in the U.S. The disease usually affects sexually mature animals and females more than males.

Laboratory Tests
Treatment
Prognosis
- Rough therefore lower virulence - mild or asymptomatic infections
- Abortions, decreased fertility, reduced litter sizes, neonatal mortality
- Orchitis and epididymitis causing infertility in male dogs
- Infertility may be permanent if chronic infection
- Slide agglutination, ELISA, agar gel immunodiffusion
- Neuter infected animals
