Preparing students for careers in food-supply veterinary medicine: a review of educational programs in the United States.

The real and/or perceived shortage of veterinarians serving food-supply veterinary medicine has been a topic of considerable discussion for decades. Regardless of this debate, there are issues still facing colleges of veterinary medicine (CVMs) about the best process of educating future food-supply veterinarians. Over the past several years, there have been increasing concerns by some that the needs of food-supply veterinary medicine have not adequately been met through veterinary educational institutions. The food-supply veterinary medical curriculum offered by individual CVMs varies depending on individual curricular design, available resident animal population, available food-animal caseload, faculty, and individual teaching efforts of faculty. All of the institutional members of the Association of American Veterinary Medical Colleges (AAVMC) were requested to share their Food Animal Veterinary Career Incentives Programs. The AAVMC asked all member institutions what incentives they used to attract and educate students interested in, or possibly considering, a career in food-supply veterinary medicine (FSVM). The problem arises as to how we continue to educate veterinary students with ever shrinking budgets and how to recruit and retain faculty with expertise to address the needs of society. Several CVMs use innovative training initiatives to help build successful FSVM programs. This article focuses on dairy, beef, and swine food-animal education and does not characterize colleges' educational efforts in poultry and aquaculture. This review highlights the individual strategies used by the CVMs in the United States.

The informatics imperative in veterinary medicine: collaboration across disciplines.

Information and data management are essential to support the collaborative and interdisciplinary pursuits of an academic veterinary medicine enterprise, ranging from research conducted by individual investigators, education processes, clinical care, and outreach to administration and management. Informatics is an academic discipline that focuses on the creation, management, storage, retrieval, and use of information and data and how technology can be applied to improve access to and use of these resources. In this article, we discuss the challenges in integrating informatics across a large academic enterprise from a veterinary medicine point of view. As a case study, we describe an example program of informatics at the University of Minnesota designed to support interdisciplinary collaboration.

Detection, characterization, and control of bovine viral diarrhea virus infection in a large commercial dairy herd.

Detection, genetic characterization, and control of bovine viral diarrhea virus (BVDV) disease in a large commercial dairy herd is reported. Precolostral BVDV serum antibody was detected in 5.3% (12/226) of newborn calves before the test and removal of persistently infected (PI) animals and in 0.4% (2/450) of newborn calves after the removal of PI heifers.

Serological evaluation of precolostral serum samples to detect Bovine viral diarrhea virus infections in large commercial dairy herds.

The authors propose that screening newborn calves for Bovine viral diarrhea virus (BVDV) antibody prior to colostrum feeding is a useful strategy to detect herds with endemic BVDV infection. In the current study, precolostral serum samples of newborn calves in 2 Minnesota and 2 California dairy farms were examined. Precolostral BVDV antibodies were detected by serum neutralization and enzyme-linked immunosorbent assay in 7.4% (33/446) and 6.2% (32/515) of newborn calves in the California and Minnesota herds, respectively. The serum samples were also tested by reverse transcription polymerase chain reaction (RT-PCR), and BVDV was detected in 1.6% (7/446) and 3.5% (18/515) of newborn calves in the California and Minnesota herds, respectively. The primary advantages of precolostral testing are that calves congenitally infected with BVDV and seropositive at birth represent a larger percentage of calves born than BVDV-viremic calves and that fewer animals would need to be tested with an antibody test than a RT-PCR or antigen detection test to detect endemic BVDV infections at the herd level. Testing for BVDV antibody in calves prior to colostrum feeding detects fetal infections in both late-gestating cows and nonlactating heifers. Precolostral serum antibody detection is not confounded by vaccination and may be a more sensitive screening method than bulk milk RT-PCR and nonvaccinated sentinel calf strategies in large dairy herds.

Infarctive purpura hemorrhagica in five horses.

Five horses were examined because of signs of muscle stiffness, colic, or both. All 5 had been exposed to Streptococcus equi within 3 weeks prior to examination or had high serum titers of antibodies against the M protein of S equi. Horses had signs of unrelenting colic-like pain and focal areas of muscle swelling. Four horses were euthanatized. The fifth responded to treatment with penicillin and dexamethasone; after 3 weeks of treatment with dexamethasone, prednisolone was administered for an additional 10 weeks. Common hematologic and serum biochemical abnormalities included neutrophilia with a left shift and toxic changes, hyperproteinemia, hypoalbuminemia, and high serum creatine kinase and aspartate transferase activities. Necropsy revealed extensive infarction of the skeletal musculature, skin, gastrointestinal tract, pancreas, and lungs. Histologic lesions included leukocytoclastic vasculitis in numerous tissues and acute coagulative necrosis resembling infarction. These horses appeared to have a severe form of purpura hemorrhagica resembling Henoch-Schönlein purpura in humans and characterized by infarction of skeletal muscles. Early recognition of focal muscle swelling, abdominal discomfort, neutrophilia, hypoalbuminemia, and high serum creatine kinase activity combined with antimicrobial and corticosteroid treatment may enhance the likelihood of a successful outcome.
