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.
Congenital brucellosis can be transmitted transplacentally, whereas neonatal brucellosis can be acquired through contact with body fluids secreted during birth or through postpartum breastfeeding.

At the same time, they create a channel or tube (called a stylostome) to suck up the liquified skin cells,” says Green. The damage from the skin breaking and the duration of how long they ate ...

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 ...
