a genus of gram-negative rods in seven species and several biotypes. The cause of many serious diseases in animals, including brucellosis.

Brucella abortus
a short rod or coccobacillus which causes brucellosis in cattle and horses, and is a serious zoonosis. Two strains of reduced virulence and used for vaccination in cattle are Strain 19 and Strain 45/20.
Brucella canis
a similar organism to the other brucellae except that it is inhibited in growth by a 10% concentration of CO2, a cultural enhancement for the other species. Causes brucellosis in dogs.
Brucella melitensis
a rod so short that it is easily mistaken for a coccus with the same characteristics as the other brucellae. Causes brucellosis in goats and Malta fever in humans, a serious zoonosis. Rev1 strains are used for vaccination but have zoonotic risk.
Brucella neotomae
found only in the desert wood rat in the USA.
Brucella ovis
has staining and cultural characteristics similar to the other brucellae. Causes brucellosis in rams.
Brucella suis
a typical brucella in morphology and cultural and staining characteristics. Causes brucellosis in pigs and is a significant zoonosis.
