One medicine: The dynamic relationship between animal and human medicine in history and at present

The relation and collaboration of human and animal medicine had its ups and downs throughout history. The interaction between these two disciplines has been especially fruitful in the broad areas of patho-physiology and of epidemiology. An exploration of the interaction between the two disciplines, using historical and contemporary examples in comparative medicine, zoonoses, zooprophylaxis, and human-animal bond, reveals that a better understanding of animal and human disease, as well as societal changes such as interest in non-conventional medicine, are leading to a broader concept of one medicine that includes animal and human medicine as well as social and other sciences.
