The Veterinary Resources branch of the SNPRC includes nine veterinarians: the Associate Director, the Assistant Director, five clinical veterinarians, and two veterinary pathologists. Additionally, the unit employs 57 technicians and 46 animal caretakers who care for 3248 nonhuman primates (census as of December 1, 2009), of which 2275 are baboons, 455 are macaques, 161 are chimpanzees, 308 are common marmosets, and 49 are other species. A Ph.D. staff scientist, a research coordinator, and several project managers from the SNPRC Research Resources branch coordinate research activities with the veterinary and veterinary technical staffs of Veterinary Resources. The medical and technical staffs provide a wide variety of observational procedures and experimental manipulations of animals in support of research projects conducted by scientists based at the SNPRC and collaborating investigators from other institutions. The group also conducts research concerned with health problems in primate colonies and surveys for unique clinical conditions that may lead to new models of human disease.
