no background in animal research and are developing genetically engineered mice, not widely developed until the last 5 years. The scientists often require training by veterinary staff to carry out experimental procedures and comply with regulations (Cork et al., 1997). It is also conceivable that as the genomes of other laboratory animal species are decoded, the demand for laboratory animal medicine veterinarians with specialized knowledge of dogs, cats, rhesus macaques, and other common laboratory animal species will increase.
Comparative medicine veterinarians are integral to the successful development and assessment of transgenic animals. They have the comprehensive knowledge of disease processes and human and rodent diseases that is necessary to develop animal models or to consult with scientists who are developing animal models (Gaertner et al., 1998). Comparative medicine veterinarians with advanced training in pathology, neurology, cardio-pulmonary physiology, and animal behavior are essential to the successful development of transgenic animals.
