Comparative medicine is a multidisciplinary field that involves the study of diseases and their treatments across different species, particularly humans and animals. It aims to improve our understanding of the similarities and differences between diseases in different species, and how these can help develop new treatments and therapies for both humans and animals. Comparative medicine also plays a key role in advancing our knowledge of disease mechanisms, genetics, and drug development. It involves collaborations between researchers in various fields such as veterinary medicine, human medicine, biology, pharmacology, and genetics.
