This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic wasting disease (CWD) is a degenerative brain disease of deer & elk that is associated with prions and is related to other transmissible spongiform encephalopathy diseases such as mad cow disease. Occurrence of CWD in western Canada and the United States have heightened concerns about the spread of CWD to Ontario. This document presents a plan to ensure that Ontario is well positioned to respond to the threats posed by CWD. It identifies the risks to wild & captive members of the deer family and provides for multi-agency co-ordination in five key areas: prevention, surveillance, control & eradication, and recovery & communications. The plan identifies roles & responsibilities for government ministries & agencies related to the potential response actions and identifies the need to collaborate with affected stakeholders & the public.

Book excerpt: Chronic wasting disease (CWD) is a fatal disease of the nervous that affects mule deer, white-tailed deer, and elk. As of July 2002, three cases of CWD have been confirmed in wild mule deer in Saskatchewan. This bulletin reviews the CWD management program that has the long-term goal of eradication of this disease. Program activities are described with regard to control of the spread of CWD and monitoring the occurrence of CWD in certain high-priority areas. The bulletin also includes answers to commonly asked questions about CWD.

Available in PDF, EPUB and Kindle. Book excerpt: Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy that was first detected in white-tailed deer (Odocoileus virginianus) in the northeastern United States (Northeast) in 2005. Maintaining a healthy population of white-tailed deer is important to states in the Northeast for numerous recreational and economic reasons. The Midwest documented a decline in hunter participation and hunter-associated revenue following detection of CWD, and the presence of CWD in the Northeast could have a similar impact on local economies and wildlife management efforts. Considering CWD is a new and emerging disease in the Northeast, I investigated sampling strategies by state, ecology of deer, and environmental drivers of disease to better understand CWD in the region.I surveyed 14 state agencies responsible for CWD surveillance in the Northeast to identify how surveillance efforts have changed following detection of CWD in the region. Annual surveillance efforts throughout the region initially exceeded 15,000 deer per year. Loss of federal funding in 2012, however, led to a drastic reduction in these efforts (

This book was released on 2006 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic wasting disease (CWD) of deer and elk is unique among the transmissible spongiform encephalopathies. Our longterm goal is to better understand the epidemiology of CWD and thus develop strategies for management and control. The specific goals of these studies are to develop sensitive assays for PrPres as a marker for infectivity, and use these techniques to monitor the dynamics and modes of shedding of PrPres from orally infected mule and white-tailed deer and elk. Finally these techniques will be applied to investigating the nature of environmental contamination that may be associated with CWD transmission. Protease resistant prion protein from brains of CWD affected deer and elk (PrPres) and cellular PrPc were purified and used in a variety of detection assays. PrPres was detected using antibody based techniques which although substantially more sensitive than any current assay still need improvement. Deer and elk have been infected orally to determine CWD shedding in vivo. In addition, in support of investigations of environmental contamination by the CWD agent, we have mapped areas of high, moderate, and low CWD contamination at two CWD endemic facilities and collected samples for assay to determine levels of the prion protein.

Book excerpt: Infectious disease systems involving wildlife are complex. Chronic wasting disease (CWD) is a highly infectious, fatal neurodegenerative disease that affects wild and captive cervids. Despite management efforts in North America, CWD is now established in 30 states and 4 Canadian provinces and disease prevalence in endemic areas is increasing. While it is well accepted that direct transmission establishes CWD outbreak areas, indirect transmission through contaminated environments may facilitate maintenance of the disease. Infected hosts shed CWD prions (PrPCWD) into the environment during a 1.5 to 2 year-long disease course, where they remain infectious for years to decades. The importance of PrPCWD shedding, the subsequent accumulation and increasing bioavailability of PrPCWD in the environment, and host behaviors that facilitate host-prion contacts are not well understood due to the challenges of detecting prions. In this dissertation, I leverage protein amplification technology, the real-time quaking-induced conversion (RT-QuIC) assay, in combination with field and additional laboratory-based approaches to help fill key knowledge gaps about ecologically- and management-relevant environmental sources of CWD transmission. I examine and characterize the relative amounts and presence or absence of PrPCWD in abiotic and biotic environmental samples. In chapter 2, I assessed the potential risk of hematophagous ectoparasites as mechanical vectors of CWD. I hypothesized that ticks are an ecologically relevant community-level factor in the CWD system, with implications for CWD transmission. I revealed that deer ticks (Ixodes scapularis) assimilate and excrete PrPCWD from inoculated blood meals using an artificial membrane feeding system and that deer ticks collected from hunter-harvested white-tailed deer (Odocoileus virginianus) contained transmission-relevant amounts of PrPCWD and may pose a CWD risk to cervids. In chapter 3, I assessed detection thresholds and relative quantification of PrPCWD in carnivore feces. I hypothesized that carnivore excrement could be used as a non-invasive surveillance approach for CWD occurrence and help disentangle the role of carnivores in CWD spread. RT-QuIC was adaptable for detection of PrPCWD from prion-spiked carnivore excrement and field samples showed that PrPCWD is detectable from free-ranging carnivores. Scat-based surveillance could facilitate CWD detection in low-prevalence areas or areas without hunter-based surveillance. In chapter 4, I assessed PrPCWD accumulation dynamics at decommissioned artificial mineral licks in southwest Tennessee. I hypothesized that these sites would still serve of foci of PrPCWD accumulation, and that site-specific management efforts, deer use, and soil characteristics would influence PrPCWD accumulation dynamics. I demonstrated that 32/49 (65%) mineral sites had PrPCWD detected in soils. Detection of PrPCWD from these artificial mineral sites was not dependent on site-specific management efforts or deer use intensity. Soil properties were very similar across sites and no correlation between PrPCWD detection and soil physical properties was found. Overall, these studies demonstrate the complex nature of CWD epidemiology and highlight the importance of teasing out details of fine-scale ecological factors and processes influencing the CWD processes. I showed that ticks readily assimilate PrPCWD from infected blood meals and have the potential to act as mechanical vectors of CWD. In addition, I furnish a way to begin understanding the relationship of cervid consumers in structuring environmental PrPCWD deposition by assessing the utility of RT-QuIC for examination of carnivore excrement. I advance the current understanding of PrPCWD accumulation dynamics at attractant sites resulting from historic foci of deer aggregation due to prior attractant supplementation leading up to nascent CWD establishment in southwest Tennessee.
