Brucella canis is a potential zoonotic agent that infects dogs and wild canidae almost exclusively. Infection by B. canis is suspected in male dogs that have epididymitis or are infertile, and in female dogs that abort in late gestation or fail to con- ceive. Occasionally, infection may manifest as systemic disease in various organs, including bone, eyes, and, rarely, brain. Brucella canis is spread via contact with the genitourinary secre- tions from infected dogs, including aborted placental and fetal material, vaginal secretions from infected females that are in heat, prostatic and seminal fluid, and urine. Following abor- tion, females may continue to shed bacteria intermittently for weeks or months
