Recent trends toward specialization in veterinary medicine parallel similar trends in the practice of human medicine. W. Jean Dodds, the new editor of Advances in Veterinary Science and Comparative Medicine, has brought together recognized authorities to integrate the legal and ethical implications generated by the issue of specialization. Routine and specialized veterinary practices, including genetic screening, are now associated with clinical trials. This book establishes the links between specialization in the veterinary sciences and the factors that influence the use of animals in basic science and medicine.
