Brucellosis is a bacterial disease mainly of domestic animals. The infection is directly transmitted to humans by animals through breaks in the skin or by contact with infected materials like aborted foetuses and placenta.

It is an important zoonosis worldwide which accounts for about 500, 000 reported human cases annually around the globe; particularly amongst agricultural and pastoral populations. It results in serious economic losses in animals due to abortion, reduced fertility, birth of weak off springs and reduced productivity. In humans, it leads to chronic debilitation resulting in low work output and subsequent negative economic impact. The paper reviews brucellosis in different species of animals. It highlights the aetiology, morphology, host |
