“…Although collection and sampling of animal carcasses represent a major data source for wildlife health surveillance, there are a number of alternative methods for accessing health information. Data from slaughtered farmed wildlife such as deer of from domestic animals potentially exposed to wildlife pathogens provide evidence of pathology as well as samples of blood and parasites [ 18 , 22 - 24 ]. Appropriate diagnostics (such as standardized health screening, ancillary diagnostic tests and thorough postmortem examinations) on diseased wild animals submitted to wildlife rehabilitation centers can enhance surveillance efforts [ 21 , 25 - 27 ].…”

In a fast changing world with growing concerns about biodiversity loss and an increasing number of animal and human diseases emerging from wildlife, the need for effective wildlife health investigations including both surveillance and research is now widely recognized. However, procedures applicable to and knowledge acquired from studies related to domestic animal and human health can be on partly extrapolated to wildlife. This article identifies requirements and challenges inherent in wildlife health investigations, reviews important definitions and novel health investigation methods, and proposes tools and strategies for effective wildlife health surveillance programs. Impediments to wildlife health investigations are largely related to zoological, behavioral and ecological characteristics of wildlife populations and to limited access to investigation materials. These concerns should not be viewed as insurmountable but it is imperative that they are considered in study design, data analysis and result interpretation. It is particularly crucial to remember that health surveillance does not begin in the laboratory but in the fields. In this context, participatory approaches and mutual respect are essential. Furthermore, interdisciplinarity and open minds are necessary because a wide range of tools and knowledge from different fields need to be integrated in wildlife health surveillance and research. The identification of factors contributing to disease emergence requires the comparison of health and ecological data over time and among geographical regions. Finally, there is a need for the development and validation of diagnostic tests for wildlife species and for data on free-ranging population densities. Training of health professionals in wildlife diseases should also be improved. Overall, the article particularly emphasizes five needs of wildlife health investigations: communication and collaboration; use of synergies and triangulation approaches; investments for the long term; systematic collection of metadata; and harmonization of definitions and methods.

“…These diseases are uncommon in Swiss domestic livestock, possibly explaining the rare occurrence in farmed deer. Furthermore, Chronic Wasting Disease does not seem to occur in Europe (Belgium [ 24 ], Germany [ 25 ], Switzerland [ 26 ]). We suggest that perinatal mortality, necrobacillosis, and endoparasites are not just problems typical of European countries, but that in North America, Australia, and New Zealand, they are overshadowed by the high prevalence of other contagious infectious diseases.…”

To investigate diseases and causes of mortality in Swiss farmed deer, deer found dead or shot due to diseased condition between March 2003 and December 2004 were requested for a complete postmortem examination. One hundred and sixty-two animals were submitted. Perinatal mortality, necrobacillosis in 3 week to 6 month old deer, and endoparasitosis in 6 month to 2 year old deer were identified as the most important causes of loss, followed by ruminal acidosis, which was diagnosed in 22% of deer older than 1 year. Congenital malformations were observed in 15% of deer less than 6 months old. Reportable infectious diseases known as major problems in deer farming in other countries were rare (yersiniosis, malignant catarrhal fever) or not observed (tuberculosis, chronic wasting disease). Overall, the results indicate that the Swiss deer population does not present major health problems of concern for domestic animals.

“…The question was whether meat from farmed game might be a risk to consumers as there was a parallel emergence of a prion disease (chronic wasting disease) in deer of Northern America. Switzerland be came one of the first European countries to investigate game species for this disease (Sieber et al, 2008(Sieber et al, , 2010. Research on wildlife was also required in the context of the eradication program of bovine virus diarrhea and of the bluetongue vaccination campaign, since wildlife populations may have acted as pathogen reservoirs (Ca saubon et al, 2012(Ca saubon et al, , 2013.…”

National competence center for wildlife diseases in Switzerland: Mandate, development and current strategies

The need for wildlife health surveillance has become increasingly recognized. However, comprehensive programs which cover a wide spectrum of species, pathogens and geographic areas are still lacking in most European countries and practical examples of systems in place remain scarce. This article provides an overview of the organization of wildlife health surveillance in Switzerland, with a focus on the development, current strategies and the activities of the national program carried out by the Centre for Fish and Wildlife Health (FIWI), University of Bern. This documentation may stimulate on-going discussions on the design and development of national wildlife health surveillance programs in other countries. Investigations into wildlife health in Switzerland date back to the 1950s. The FIWI acts as a national competence center for wildlife diseases on mandate of the Swiss federal authorities. The mandate includes four main activities: disease diagnostics, research, consulting and teaching. In line with this, the FIWI has made continuous efforts to strengthen a national network of field partners and implemented strategies to facilitate long-term and metastudies.
