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.

Download or read book Microbial Zoonoses and Sapronoses written by Zdenek Hubálek and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state of art in the field of microbial zoonoses and sapronoses. It could be used as a textbook or manual in microbiology and medical zoology for students of human and veterinary medicine, including Ph.D. students, and for biomedicine scientists and medical practitioners and specialists as well. Surprisingly, severe zoonoses and sapronoses still appear that are either entirely new (e.g., SARS), newly recognized (Lyme borreliosis), resurging (West Nile fever in Europe), increasing in incidence (campylobacterosis), spatially expanding (West Nile fever in the Americas), with a changing range of hosts and/or vectors, with changing clinical manifestations or acquiring antibiotic resistance. The collective term for those diseases is (re)emerging infections, and most of them represent zoonoses and sapronoses (the rest are anthroponoses). The number of known zoonotic and sapronotic pathogens of humans is continually growing − over 800 today. In the introductory part, short characteristics are given of infectious and epidemic process, including the role of environmental factors, possibilities of their epidemiological surveillance, and control. Much emphasis is laid on ecological aspects of these diseases (haematophagous vectors and their life history; vertebrate hosts of zoonoses; habitats of the agents and their geographic distribution; natural focality of diseases). Particular zoonoses and sapronoses are then characterized in the following brief paragraphs: source of human infection; animal disease; transmission mode; human disease; epidemiology; diagnostics; therapy; geographic distribution.

Download or read book Environmental Aspects of Zoonotic Diseases written by Robert Armon and published by IWA Publishing. This book was released on 2012-01-31 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Aspects of Zoonotic Diseases provides a definitive description, commentary and research needs of environmental aspects related to zoonotic diseases. There are many interrelated connections between the environment and zoonotic diseases such as: water, soil, air and agriculture. The book presents investigations of these connections, with specific reference to environmental processes such as: deforestation, floods, draughts, irrigation practices, soil transfer and their impact on bacterial, viral, fungal, and parasitological spread. Environmental aspects such as climate (tropical, sub-tropical, temperate, arid and semi-arid), developed and undeveloped countries, animal (domestic and wild) traffic animal border crossing, commercial animal trade, transportation, as well geography and weather on zoonosis, are also discussed and relevant scientific data is condensed and organized in order to give a better picture of interrelationship between the environment and current spread of zoonotic diseases. Altogether, the book presents a remarkable and a vast amount of potential future research directions based on the link: environment-vectors-pathogens-humans. The most up-to-date source of information on this increasingly important cross-disciplinary subject, Environmental Aspects of Zoonotic Diseases will be invaluable for environmentalists, veterinarians, medical staff, environmental engineers, government agencies and consultants working in this field.
