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 ]
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.
Sir David Bruce isolated B. melitensis from British soldiers who died from Malta fever in Malta.After exposure to Brucella, humans generally have a two- to four-week latency period before exhibiting symptoms, which include acute undulating fever (>90% of all cases), headache, arthralgia (>50%), night sweats, fatigue, and anorexia.

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 ...

Brucella suis is a bacterium that causes swine brucellosis, a zoonosis that affects pigs. The disease typically causes chronic inflammatory lesions in the reproductive organs of susceptible animals or orchitis , and may even affect joints and other organs. [ 1 ]
Brucellosis is a zoonotic disease: marine mammal brucellosis can infect other species, including human beings. Brucella spp. are gram-negative in their staining morphology. Brucella spp. are poorly staining, small gram-negative coccobacilli (0.5-0.7 x 0.6-1.5 μm), and are seen mostly as single cells
