In 2015, a major outbreak of highly pathogenic avian influenza virus (HPAIV) infection devastated poultry facilities in Minnesota, USA. To understand the potential role of wild birds, we tested 3,139 waterfowl fecal samples and 104 sick and dead birds during March 9–June 4, 2015. HPAIV was isolated from a Cooper’s hawk but not from waterfowl fecal samples.

This paper describes dog owner and veterinarian perceptions around the use of a validated canine quality of life (QOL) survey to facilitate wellness conversations in two clinical settings: a veterinary teaching hospital (pilot, Phase 1) and five corporate general practice hospitals (Phase 2). Phase 1 results showed that dog owners felt the survey was valuable for understanding their dog's QOL, with 81% of owners expressing interest in learning more about canine QOL. Phase 2 reinforced owner perceptions about the survey conveyed during the pilot phase, and veterinarians reported that the survey facilitated client communication related to preventive care without increasing consultation time. These results demonstrate that beyond using QOL assessments to track patient health, the use of a QOL survey during veterinary visits could improve owner-veterinarian discussions around QOL, wellness, services and preventive care. To fully realize these benefits in clinical settings, veterinary staff preparation may be needed to communicate the purpose of QOL assessments to clients and thus facilitate deeper conversations about client needs and concerns. Key tools for achieving these could therefore include (1) sufficient veterinary team training to understand the QOL assessment and its purpose (2) training in how to communicate QOL to clients, and (3) reflexive use of QOL assessment results to engage clients in preventive care discussions. The veterinarian and client can then discuss the pros and cons of the various aspects of QOL and preventive care to arrive at a cooperative decision.

Heart mitochondria, isolated from rats fed diets deficient or supplemented with vitamin E (E) and/or selenium (Se), were subjected to time-course assays of lipid peroxidation stimulated by ascorbate/ADP/Fe 3.. Mitochondria depleted of a-tocopherol (a-TH) peroxided rapidly as assessed by formation of thiobarbituric acid reactive substances (TBARS). Formation of TBARS was strongly inhibited in mitochondria from rats fed diets supplemented with E. Selenium deficiency, reduced glutathione (GSH), glutathione disulfide (GSSG) or GSH + GSSG did not affect the course of lipid peroxidation in mitochondda from rats supplemented or deficient in E. Combined E and Se deficiency resulted in significantly lower total (oxidized + reduced) mitochondrial coenzyme Q-9 (CoQ-9) concentration compared with control rats supplemented with dietary E and Se. Time-course changes in mitochonddal a-TH and total CoQ-9 during oxidizing conditions were minor in +E rats. Total CoQ-9 was reduced substantially, however, during the course of lipid peroxidation in mitochondria depleted of a-TH. Selenium-dependent glutathione peroxidase (Se-GSHPx) activity was reduced by approximately 96% in heart cytosol, and to a somewhat lesser extent in mitochondria, by dietary Se deficiency. Non-Se GSHPx activity was not detected in heart cytosol but was detected in very small amounts in heart mitochondria. Glutathione S-transferase activity of heart cytosol was decreased in E and/or Se deficiency. The results of these experiments indicate that membrane a-TH was most effective in inhibiting lipid peroxidation in heart mitochondria.

Recent uses for rumen boluses, such as mortality implant transmitters (MITs), in wildlife have made it necessary to adapt deployment techniques developed for livestock. In 29 and 30 attempts to place MITs in Minnesota free-ranging moose ( Alces alces) in 2013 and 2014, respectively, success was achieved 83% and 63% of the time. In 2014, new methods for MIT deployment were evaluated in captive moose in Alaska. Mandible measurements provided guidance for selection of an appropriate-sized bolus applicator. A Schulze mouth gag was used to aid insertion of the applicator, and canola oil was used to lubricate the bolus to facilitate swallowing. Time to first swallow and time to continuous swallow following sedative reversal was measured to gauge appropriate timing for bolus administration. Using the adapted technique with trained personnel, success rates for MIT deployment were 100% (10/10) for captive moose and 88% (21/24) for free-ranging moose in Minnesota in 2015.

As a result of the growing need for public-health veterinarians, novel educational programs are essential to train future public-health professionals. The University of Minnesota School of Public Health, in collaboration with the College of Veterinary Medicine, initiated a dual DVM/MPH program in 2002. This program provides flexibility by combining distance learning and on-campus courses offered through a summer public-health institute. MPH requirements are completed through core courses, elective courses in a focus area, and an MPH project and field experience. Currently, more than 100 students representing 13 veterinary schools are enrolled in the program. The majority of initial program graduates have pursued public-practice careers upon completion of the program. Strengths of the Minnesota program design include accessibility and an environment to support multidisciplinary training. Continued assessment of program graduates will allow for evaluation and adjustment of the program in the coming years.
