Brucellosis is a zoonotic disease (a disease of animals transmissable to humans) caused by. infection with any of 4 species of Brucella. B. abortus, B. melitensis, and B. suis are the. most common pathogenic species, with rare cases reported due to infection with B. canis.
Brucella abortus. Description and significance. Brucella abortus is a gram-negative bacterium that is found in cattle populations (1). This intracellular parasite is a blood borne pathogen that causes premature abortion of a cattle fetus. What makes this bacterium so dangerous is that it is zoonotic, meaning it can be transferred from an animal to a human host and still remain pathogenic (3).
