    Brucellosis is caused by bacteria of the genus Brucella and is characterized by abortion, retained placenta, and to a lesser extent, orchitis and infection of the accessory sex glands in males. The disease occurs in most countries. It primarily affects cattle, buffalo, bison, pigs, sheep, goats, dogs, elk, and occasionally horses. The disease in humans, referred to as undulant fever, is a serious public health problem, especially when caused by B melitensis.
