The historical process of brucellosis extends back to humankind's first contact with animals. Although brucellosis is a sporadic disease observed in animals in certain regions of the world, it is an important disease in humans that can affect many organs and systems due to the consumption of contaminated milk or milk products. Studies have shown that the presence of Brucella dates back to 60 million years ago. In 450 BC, Hippocrates described a disease similar to brucellosis. Since Hippocrates' time, brucellosis has been characterized by fever. Our aim is to investigate selfless work undertaken by scientists on the epidemiology, diagnosis and clinical findings of brucellosis until today, and to gain a historical perspective about the disease that is as old as human history, still has importance today, causes economic losses in treated animals and harms human health.
