A New Decade of Veterinary Research: Societal Relevance, Global Collaboration, and Translational Medicine

Veterinary research and clinical contributions reach into every aspect of biomedical health and science: livestock production and food safety; zoonotic diseases, epidemiology, and public health; comparative basic and translational research; companion animal medicine and surgery; animal welfare and the human-animal bond; and wildlife and ecosystem health. Diversity is not only a key strength of veterinary science but also a challenge. Veterinary research in the next decade must strengthen the scientific impact of its core mission in animal health while firmly reinforcing its societal and global relevance. Key research challenges include water- and food-borne pathogens and drug residues, zoonotic pathogens and infectious diseases, and evidence-based companion animal medicine and its translational applications to human health. Meeting these challenges will require cross-disciplinary global collaborations, significant national research investment, and innovative online publishing tools to facilitate networking and open scientific exchange.

A GLANCE OVER OUR SHOULDER: VETERINARY RESEARCH 2010-2014
Future research builds on past achievements and responds to emerging needs. Veterinary research publications in the past 5 years provide a snapshot of recent accomplishments and serve as a pivot point for identifying future challenges. A Web of Science search (2010-2014) was done to identify top-cited articles, group authors, and funding agencies in the veterinary science research area (1). The search was conducted on all databases to identify veterinary research within a broad context, and then on the Web of Science Core Collection for a more specific veterinary focus. Citations are only one metric of scientific impact, but were used here to identify research areas receiving relatively high attention from other researchers; they were calculated per year so recent articles were not disadvantaged.
Highly cited articles fell into three major areas that point to challenges for veterinary research in the future: environmental threats to animal and human health, pathogens and zoonoses, and comparative medicine and pathology (Table 1). These areas stress the global reach of veterinary science and the strong momentum of the One Health Initiative, which emphasizes interconnectedness between animal, human, and environmental health (2). They also reflect a growing emphasis on diseases of companion animals and their expanding role as translational models of human disease.
Funding was led by Brazilian government ministries and Sao Paolo Research Foundation, which together supported 66 veterinary publications, compared with the European Union (29), UK Department for Environment, Food, and Rural Affairs (24), and US National Institutes of Health (18). Several articles funded by the Korean government and National Research Foundation and the National Natural Science Foundation of China suggest that increased veterinary research output from Asia is poised to continue (3).

COMMON GROUND: ENVIRONMENTAL THREATS
Animals and humans share the same environment. Threats to environmental quality by pharmaceutical and pesticide contamination of food and water, and evolving bacterial drug resistance, including methicillin-resistant Staphylococcus aureus (MRSA), jeopardize human and animal health and will continue to present a major research challenge for veterinary scientists in the next decade (4). Potential health risks for people who work closely with animals are a top priority. Research also is needed to identify sources of animal and veterinary drugs; assess the role of animals as reservoirs of resistant pathogens; establish interspecies transmission routes (including human to animal); determine risk factors and epidemiology; monitor and adapt agricultural practices; standardize laboratory testing of food pathogens and drug residues; and develop new and effective treatments. Aquaculture-related environmental residues and impact are also a priority (5). Environmental threats require a global collaborative approach by veterinarians, physicians, microbiologists, pharmacologists, toxicologists, analytical chemists, and environmental scientists, as well as a focus on rapidly developing and highly populated countries such as China and India to address agricultural practices, environmental degradation, and their links with animal and human health (6).

TRACKING PATHOGENS: ZOONOTIC AND INFECTIOUS DISEASES
Animals and humans share pathogens. One need only consider the origin of the Ebola epidemic: fruit bats living in a hollow tree in Guinea (7). Zoonotic and infectious diseases -bacterial, viral, fungal, protozoal, and parasitic -will continue to dominate veterinary research efforts on a global basis, including novel research on Frontiers in Veterinary Science www.frontiersin.org    (10) is a key research priority. Infectious and zoonotic diseases intersect with the realities of porous borders, regional conflicts, and a range of agricultural, economic, and political systems that affect veterinary and public health. Outbreaks of foot-and-mouth disease and mutations in avian influenza virus in Egypt exemplify the difficulty many countries face in disease surveillance and vaccine compliance. Consortia such as Partners for Rabies Prevention, Cysticercosis Working Group of Peru, and Emerging Babesioses and One Health are important strategies for galvanizing global research support, expertise, and resources. The $100 million PREDICT project brings together ecosystem, wildlife, and disease experts is an unprecedented effort to detect and respond to viruses that move among people, livestock, and wildlife (11).

COMPANION ANIMAL MEDICINE AND PATHOLOGY: THE NEW TRANSLATIONAL MODEL
Animals and humans share disease concerns, from diabetes to cancer to kidney disease. Continued specialization of companion animal practice -dogs, cats, and horses -has emerged as a parallel microcosm of its human counterpart. Research that advances high quality, evidence-based veterinary practice is essential for improving clinical outcomes and quality of life. Challenges include coordination of clinical trials and multi-institutional studies, improved database quality, and implementation of reporting guidelines (12). Technological advances in diagnostic imaging, laboratory testing, surgical techniques, epidemiologic modeling, and drug therapy of companion animals are accelerating and globalizing. The past 5 years have seen a surge in evidence-based practice guidelines ranging from dental care for dogs and cats (13) to quality assurance in clinical laboratories (Table 1) to advanced life support and CPR (14). These guidelines promote evidence-based medicine, raise the level of veterinary care, and stimulate discussion within the profession.
Companion animal medicine and pathology is the new frontier of translational medicine, engaging both veterinary and medical scientists in the realworld clinical laboratory of naturally occurring disease in animals. While veterinary researchers have long relied on medical research as a basis for investigation and therapy in animals, medical researchers now increasingly look to veterinary research and veterinarians to gain insights and develop translational models of human disease. Important recent examples include novel therapies for melanoma and lymphoma; obesity, nutritional and metabolic disease; aging and degenerative diseases such as osteoarthritis; behavioral and cognitive disorders; and regenerative medicine and stem cell therapy ( Table 1). The Veterinary Comparative Oncology Working Group (15) and the comparative sequencing program of the National Institutes of Health (16) exemplify the productive collaborations possible between veterinary and medical clinicians and scientists.

AN EMERGING FRONTIER: VETERINARY AND SOCIAL SCIENCE RESEARCH
Animals and humans share a social context. The interface between animals and humans in mental health, cancer detection, war, elder care, legal guardianship, and domestic abuse highlights the diverse societal relevance of veterinary science outside traditional biomedical fields and warrants scientifically rigorous research. In addition to well-established research on the human-animal bond, veterinary research also must contribute to the scientific discussion on human euthanasia, healthcare economics, and disaster management and planning. More research is also needed on people who live and work with animals to address addiction, stress, and suicide risk (Table 1), moral behavior, and the cultural, religious, and ethical issues affecting animal and human health and welfare.

PUBLISHING TOOLS TO ADVANCE VETERINARY RESEARCH
Frontiers in Veterinary Science is a networked, collaborative, open access journal dedicated to the communication, discussion, and dissemination of all aspects of veterinary research. The journal's core mission in animal health embraces the One Health concept in all of its specialty sections, from Animal Behavior and Welfare to Zoological and Aquatic Medicine. Frontiers in Veterinary Science is closely linked with medicine, public health, and environmental and social science domains, facilitating a seamless, integrative approach to biomedical research that emphasizes the societal relevance and global reach of veterinary science while highlighting new developments in veterinary practice and their translational potential for human medicine.
Open access and online publishing open exciting new ways to share, discuss, and publish veterinary research. The Frontiers collaborative peer review system engages authors and reviewers cooperatively and enhances editors' ability to bring cross-disciplinary expertise to manuscript evaluation. Post-publication commenting enables "audience participation" and social networking redefines research communities. These novel approaches help us think about and solve today's interconnected biomedical problems in new ways.
Challenges in the next decade of veterinary research, including environmental threats, pathogens, and comparative medicine, will be driven by societal relevance, global engagement, and the need for new translational models. With the help of online publishing innovations such as Frontiers in Veterinary Science, the unique contributions made by veterinary science will be both reinforced and integrated within the broader context of biomedical and social sciences, united in the shared goal of improving the health of animals, people, and the planet.
