Brucellosis is an infection with a bacterium of one of the Brucella species, usually Brucella abortus (cattle), Brucella melitensis, Brucella ovis (sheep, goats), Brucella suis (pigs), or rarely Brucella canis (dogs). Its distribution is worldwide, but it is most common in the Mediterranean regions, Africa, the Middle East, India, Central Asia, Mexico, and Central and South America.

Persons at highest risk of brucellosis are those who work with animals that are infected, such as veterinarians and ranchers, and persons who consume raw milk or cheeses made with raw milk. Brucellosis also may be transmitted to humans if they are exposed inadvertently to live brucellosis vaccine by a needlestick or other accident.

The incidence in the United States is fewer than 0.5 cases per 100,000 population.
