Describe the extent to which your facilities are centralizedAnimals housed in 5+ separate locations
Vivarium Square Feet300,000
Summarize the nature of the animal population and the predominant types of clinical activitiesAll species of laboratory animals, to include rodents, dogs, cats, rabbits, pigs, sheep, nonhuman primates, birds, shrews, and aquatic species. Complete surgical support and rodent diagnostic laboratory support. The institution maintains germ-free and gnotobiology laboratories, an Institute of Gene Therapy, and Transgenic Core Facilities.

Penn is highly ranked nation-wide among schools of medicine in PHS-funded biomedical research. Major categories of biomedical research conducted within the School of Medicine include cancer, cell biology, imaging, anesthesia, surgery, infectious disease, cell therapy, gene therapy, transplantation, genetics, heart disease, neuroscience and immunology.

Species covered as part of clinical training.
1. Swine, macaques, dogs and cats make up the majority of our large animal clinical caseload. 
2. Species which residents will obtain significant experience with include ferrets, guinea pigs, rabbits, tree shrews, musk shrews, gerbils, hamsters, frogs, fish, and birds.
3. Residents will have regular and significant training in mice and rats in various housing parameters (conventional vs. barrier) and under differing disease statuses including various animal biosafety levels (ABSL1-3). 
4. Residents will have the opportunity to spend several days at New Bolton Center, Penn's agricultural research site, where they will have some exposure to research/teaching herds of large animals (horses, cattle, swine, small ruminants, camelids).

Give an overview of this program, describing its particular strengths and any unique aspects that are not addressed in any of the other sectionsThis program is participating in the VIRMP and thus will require applications to be uploaded with our program selected for consideration as described in the VIRMP website; interviews will be completed by early winter, and automated matching will occur as determined by VIRMP. Please be sure to review the directions on the ASLAP ( main website and VIRMP website (!!


The University of Pennsylvania is a large academic institution with a wide array of species used as animal models at one of the most highly funded biomedical research institutions in the country. University Laboratory Animal Resources (ULAR)provides clinical, husbandry, and financial support for the care and use of animals used in biomedical research on campus.

The residency program is organized into a 3-year program that emphasizes clinical medicine, lab animal pathology, regulatory affairs, and administration of a complex and diverse laboratory animal program. In addition to two years of clinical rotations (years 1 and 3), one year is provided for exclusive research training in an area of interest to the resident.

The training program is officially recognized by the American College of Laboratory Animal Medicine (ACLAM), and program completion satisfies eligibility requirements for specialty board certification.

The objective of the University of Pennsylvania ACLAM Training Program is to provide graduate veterinarians the clinical and research training necessary to become skilled laboratory animal veterinarians and become contributing members of the laboratory animal medicine community. Through the intense didactic component of the program and mentored research experience with the goal providing a first authored publication in a peer reviewed journal, this program will work to preparing the residents to succeed at the board examination.

The Penn Training Program is administered within the Division of Laboratory Animal Medicine in the Department of Pathobiology in the School of Veterinary Medicine. This allows for routine interaction (rounds, Dept. seminar series) of our residents with the veterinary anatomic and clinical pathology residents and faculty of this academic department. This close relationship with the School of Veterinary Medicine, as well as the School of Medicine, will allow for clinical and research collaborations in pursuit of the publication required for eligibility for ACLAM boards.
