Some vaccines used in livestock, most notably B. abortus strain 19, also cause disease in humans if accidentally injected. Brucellosis induces inconstant fevers, miscarriage, sweating, weakness, anemia, headaches, depression, and muscular and bodily pain. The other strains, B. suis and B. canis, cause infection in pigs and dogs, respectively.
Human and animal brucellosis share the persistence of the bacteria in tissues of the mononuclear phagocyte system, including the spleen, liver, lymph nodes, and bone marrow. Brucella can also target the male reproductive tract. [7] Globally, an estimated 500,000 cases of brucellosis occur each year. [7]
Brucella canis is a Gram-negative bacterium in the family Brucellaceae that causes brucellosis in dogs and other canids. It is a non-motile short-rod or coccus-shaped organism, and is oxidase , catalase , and urease positive. [ 1 ]

A few of the symptoms of brucellosis include: fever, chills, headache, backache, and weight loss. As with any disease, there can be serious complications; endocarditis and liver abscess are a couple of complications for brucellosis. [7] Although rare, B. abortus (and other Brucella spp.) can be transmitted between humans, usually via sexual ...
