Wisely, PhD Associate Professor UF/IFAS Department of Wildlife Ecology and Conservation Gainesville, Florida, USA 4 August 5 - 10, 2018 | St. Augustine, FL, USA Welcome Letter Dear Attendees, Welcome to St. Augustine, the First Coast of Florida, home of the oldest colonial city in the United States, and venue for the 67th International Conference of the Wildlife Disease Association. We have a wonderful scientific program that includes workshops, special sessions and a symposium. In addition to the amazing science that you will see showcased, we have planned plenty of time for networking, reconnecting with old friends and making new friends. The Wednesday afternoon break offers you the opportunity to enjoy the sites of northern Florida on your own or on one of the scheduled field trips. The theme for this year’s conference is “Connecting Wildlife Health, Conservation, and Management in a Changing World.” The theme was inspired by the Florida Interagency Wildlife Disease Working Group, an informal assembly of wildlife veterinarians, ecologists, disease biologists, and epidemiologists from state and federal agencies and academia, which meets quarterly to discuss pressing issues in wildlife diseases in our state. The individuals that comprise this group have different goals and varied perspectives on wildlife populations and the diseases that they carry, yet the working group provides a professional milieu in which people can connect. They ultimately came up with the crazy idea that they could host a conference! This meeting would not have been possible without the time and contributions of many institutions and people. The organizing committee is grateful to our platinum sponsors, the University of Florida Institute of Food and Agricultural Sciences’ Cervid Health Research Initiative and the Florida Fish and Wildlife Conservation Commission, as well as to our many other sponsors who helped keep conference registration costs down. The US Fish and Wildlife Service, UF Department of Wildlife Ecology, UF College of Veterinary Medicine, UF student chapter of the WDA, UF/IFAS Office of Conferences and Institutes and others have contributed time and effort to making this conference a reality. We thank all of the professionals and students who have volunteered their time before, during and after this conference to make the workshops, field trips, auction, photo contest, mentor event and symposium possible. We have over 350 registered attendees from 27 countries and 44 US states. We have 104 oral presentations and 124 posters including our student showcase on Tuesday. Our scientific program has special sessions on outbreak investigations and response, global wildlife health capacities, marine health and emerging diseases of herpetofauna, just to name a few. Our workshops include vampire bat management, diagnostic sample handling and processing, and crocodilian health. On our final day, we have a Cervidae Health Science Symposium focused on farmed deer health. Please take advantage of these innovative science opportunities, and be sure to get out and explore the gorgeous surroundings of St. Augustine, Florida, USA! Enjoy the conference and have a wonderful time in Florida!

Allender1, Laura Adamovicz1, Sarah Baker2, Ethan Kessler2, Marta Kelly1, Samantha Johnson1, Michael Dreslik2, Christopher A. Phillips2 1Wildlife Epidemiology Laboratory, College of Veterinary Medicine, University of Illinois, Urbana, IL, USA 2Illinois Natural History Survey, Prairie Research Institute, Champaign, IL, USA Modeling is a powerful tool for extracting information from complex systems. It is frequently used to target mitigation efforts for wildlife diseases. However, controlling disease is challenging and strategies, which focus on supporting robust population health instead, may improve conservation outcomes. The objective of this study was to model predictors of health in free‐living ornate box turtles (Terrapene ornata ornata) and identify factors, which support positive health status. We hypothesized that physical examination (PE) abnormalities and protein electrophoresis (EPH) values would best predict poor health. Turtles (N=168) from an Illinois prairie restoration site were evaluated using PE, hematology, plasma biochemistry, EPH, and hemoglobin‐binding protein in May 2016 and 2017. DNA from oral/cloacal swabs and blood was assayed for four ranaviruses, three Mycoplasma spp., three herpesviruses, two Salmonella spp., Terrapene adenovirus, intranuclear coccidiosis, Borrelia burgdorferi, and Anaplasma phagocytophilum using qPCR. Health was modeled as a categorical outcome using structural equation modeling and Bayesian network modeling, followed by information‐theoretic model ranking. “Healthy” turtles had 1) no significant PE abnormalities, 2) no pathogens affecting clinical condition, and 3) fewer than three abnormal bloodwork values. Turtles violating these criteria were classified as “Unhealthy”. Many turtles examined (51‐59%) had shell damage from suspected predator trauma. Pathogen detection (adenovirus, Terrapene herpesvirus 1) was not related to health status. Predictors of “Unhealthy” classification from the most parsimonious model included the presence of shell abnormalities and deviations from population median values for total leukocyte count, eosinophils, basophils, and heterophil:lymphocyte ratios (p<0.05). Modeling demonstrated that PE and hematology sufficiently predict health within this population, and that commonly‐identified pathogens do not significantly impact individual health. Mesopredator control was recommended to support overall population wellness. This study reveals the feasibility of modeling health in wildlife and illustrates its use for identifying clinically useful diagnostic tests and informing practical conservation interventions.

  • Transcriptomic Analysis of the Temporal Host Response to Skin
    Burgess et al. BMC Genomics 2010, 11:624 http://www.biomedcentral.com/1471-2164/11/624 RESEARCH ARTICLE Open Access Transcriptomic analysis of the temporal host response to skin infestation with the ectoparasitic mite Psoroptes ovis Stewart TG Burgess*, David Frew, Francesca Nunn, Craig A Watkins, Tom N McNeilly, Alasdair J Nisbet, John F Huntley Abstract Background: Infestation of ovine skin with the ectoparasitic mite Psoroptes ovis results in a rapid cutaneous immune response, leading to the crusted skin lesions characteristic of sheep scab. Little is known regarding the mechanisms by which such a profound inflammatory response is instigated and to identify novel vaccine and drug targets a better understanding of the host-parasite relationship is essential. The main objective of this study was to perform a combined network and pathway analysis of the in vivo skin response to infestation with P. ovis to gain a clearer understanding of the mechanisms and signalling pathways involved. Results: Infestation with P. ovis resulted in differential expression of 1,552 genes over a 24 hour time course. Clustering by peak gene expression enabled classification of genes into temporally related groupings. Network and pathway analysis of clusters identified key signalling pathways involved in the host response to infestation. The analysis implicated a number of genes with roles in allergy and inflammation, including pro-inflammatory cytokines (IL1A, IL1B, IL6, IL8 and TNF) and factors involved in immune cell activation and recruitment (SELE, SELL, SELP, ICAM1, CSF2, CSF3, CCL2 and CXCL2). The analysis also highlighted the influence of the transcription factors NF-kB and AP-1 in the early pro-inflammatory response, and demonstrated a bias towards a Th2 type immune response.

These animals are subjected to a great amount of stress and the use of long-acting neuroleptics (LANs) has become a common practice to minimize animal stress. Long-acting neuroleptics suppress behavioural responses without affecting spinal and other reflexes, and can be administered in such a manner that a single dose results in a therapeutically effective tissue concentration for anywhere between three to seven days.

  • L'opposizione Tra La Considerazione Morale Degli Animali E L'ecologism
    Distinti principi, conseguenze messe a confronto: l’opposizione tra la considerazione morale degli animali e l’ecologismo1 Different principles, compared consequences: the opposition between moral consideration towards animals and ecologism di Oscar Horta [email protected] Traduzione italiana di Susanna Ferrario [email protected] Abstract Biocentrism is the position that considers that morally considerable entities are living beings. However, one of the objections is that if we understand that moral consideration should depend on what is valuable, we would have to conclude that the mere fact of being alive is is not what makes someone morally considerable. Ecocentrism is the position that holds that morally valuable entities are not individuals, but the ecosystems in which they live. In fact, among the positions traditionally defended as ecologists there are serious divergences. Some of them, biocentrists, in particular, can ally themselves with holistic positions such as ecocentrism on certain occasions. 1 Si ripubblica il testo per gentile concessione dell’autore.

  • Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands
    Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands David Gori, Gitanjali S. Bodner, Karla Sartor, Peter Warren and Steven Bassett September 2012 Animas Valley, New Mexico Photo: TNC Preferred Citation: Gori, D., G. S. Bodner, K. Sartor, P. Warren, and S. Bassett. 2012. Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands. Report prepared by The Nature Conservancy in New Mexico and Arizona. 85 p. i Executive Summary Sky Island grasslands of central and southern Arizona, southern New Mexico and northern Mexico form the “grassland seas” that surround small forested mountain ranges in the borderlands. Their unique biogeographical setting and the ecological gradients associated with “Sky Island mountains” add tremendous floral and faunal diversity to these grasslands and the region as a whole. Sky Island grasslands have undergone dramatic vegetation changes over the last 130 years including encroachment by shrubs, loss of perennial grass cover and spread of non-native species. Changes in grassland composition and structure have not occurred uniformly across the region and they are dynamic and ongoing. In 2009, The National Fish and Wildlife Foundation (NFWF) launched its Sky Island Grassland Initiative, a 10-year plan to protect and restore grasslands and embedded wetland and riparian habitats in the Sky Island region. The objective of this assessment is to identify a network of priority grassland landscapes where investment by the Foundation and others will yield the greatest returns in terms of restoring grassland health and recovering target wildlife species across the region.

  • Sarcoptes Scabiei: Past, Present and Future Larry G
    Arlian and Morgan Parasites & Vectors (2017) 10:297 DOI 10.1186/s13071-017-2234-1 REVIEW Open Access A review of Sarcoptes scabiei: past, present and future Larry G. Arlian* and Marjorie S. Morgan Abstract The disease scabies is one of the earliest diseases of humans for which the cause was known. It is caused by the mite, Sarcoptes scabiei,thatburrowsintheepidermisoftheskinofhumans and many other mammals. This mite was previously known as Acarus scabiei DeGeer, 1778 before the genus Sarcoptes was established (Latreille 1802) and it became S. scabiei. Research during the last 40 years has tremendously increased insight into the mite’s biology, parasite-host interactions, and the mechanisms it uses to evade the host’s defenses. This review highlights some of the major advancements of our knowledge of the mite’s biology, genome, proteome, and immunomodulating abilities all of which provide a basis for control of the disease. Advances toward the development of a diagnostic blood test to detect a scabies infection and a vaccine to protect susceptible populations from becoming infected, or at least limiting the transmission of the disease, are also presented. Keywords: Sarcoptes scabiei, Biology, Host-seeking behavior, Infectivity, Nutrition, Host-parasite interaction, Immune modulation, Diagnostic test, Vaccine Background Classification of scabies mites The ancestral origin of the scabies mite, Sarcoptes scabiei, Sarcoptes scabiei was initially placed in the genus Acarus that parasitizes humans and many families of mammals is and named Acarus scabiei DeGeer, 1778.
