animals (see Chapter 3, “Increase in the Number of NIH-funded Grants Utilizing Animal Research,” for further discussion). These data suggest that the current number of veterinary principal investigators who are conducting long-term research programs in the United States is not adequate, yet the training and experience that comparative medicine veterinarians possess makes them uniquely qualified to carry out animal research successfully. Because of the importance of using animal models in translational research, the veterinary principal investigator can also provide a critical bridge between the bench scientist and the clinical researcher. The necessity of veterinarians directly participating in and carrying out biomedical research was acknowledged during testimony at the NIH reauthorization hearings in 1996, when it was asserted that more efforts should be made to recruit veterinarians to interdisciplinary research teams (Cassell and McCauley, 1996).
