Emerging Infectious Disease: Host and Parasite Perspectives
… understanding the consequences of human-mediated disease introduction. The drastic declines of native Hawaiian birds due to avian malaria provided the impetus for examining more closely several aspects of host-parasite interactions in this system. Host-specificity is an important character …

Exploring the drivers and consequences of emerging infectious disease of wildlife
Emerging infectious diseases of wildlife have threatened host populations of diverse taxa in recent history, which is largely attributable to anthropogenic global change. In three data chapters, this dissertation examines the drivers of individual- to population-level variation in how host …

Use of environmental variables to infer gene flow and population structure in the gopher tortoise (Gopherus polyphemus) and predict the seroprevalence of an emerging infectious disease
… reptiles due to factors such as habitat loss and emerging infectious disease has become an increasingly important focus in conservation biology. Here, I use novel approaches from the field of landscape genetics to combine spatial genetic data with landscape data at both regional and local spatial …

Tradeoffs and co-benefits among impacts of contrasting livestock systems
… on pig production, I explored the viral zoonotic emerging infectious disease risks of contrasting ways of meeting livestock product demand (Chapter 5). Analyses to date typically ignore how land use affects emerging infectious disease risks. I created a framework that considered risk factors …

Integrating Pandemic through Preparedness: Global Security and the Utility of Threat
Emerging infectious disease has become a paradigmatic way of thinking about disease in recent years. In response to the widely-held view that an emerging pandemic is an imminent, albeit uncertain, event linked to global interconnectedness, pandemic preparedness has been the target of considerable …

Childhood immunizations in four districts in rural Pakistan : a comparison of immunization uptake across study years (1994 and 1997) and an analysis of correlates
… have been introduced in Pakistan, new and emerging infectious disease remains a concern in the country. The province of Sindh, Pakistan is of special concern because of its large rural population.The purpose of this study was to: 1) determine and compare complete and age-appropriate …

Genetic structure and disease prevalence of boreal toads (Bufo boreas) in Glacier National Park
… though many declines have been linked to the emerging infectious disease chytridiomycosis. Additionally, amphibians are physiologically constrained to moist habitats and considered poor dispersers; thus, they may suffer genetic consequences of population isolation. To address threats to the …

The role of the P28 multigene family in the pathogenesis of Ehrlichia chaffeensis infection.
… animal hosts. <i>E. chaffeensis</i> causes the emerging infectious disease, human monocytic ehrlichiosis (HME), a potentially fatal illness. Although easily treated with tetracycline, due to its obligate intracellular parasitism it is difficult to diagnose by routine clinical methods. <i>E. …

The Highly Pathogenic Avian Influenza A(H5N1) Virus: a twenty-year journey of narratives and (in)secure landscapes
… unique aspect of the H5N1 virus's journey as an emerging infectious disease -- its representation as a potential weapon for bioterrorists. The US government's recent attempt to secure what constitutes H5N1 knowledge produced a global debate between scientists and policy makers over how to balance …

Mosquito Menace: Dengue Fever and Public Health in Singapore, 1965 – 2000
… the world’s fastest growing vector-borne disease, is often framed as a “neglected tropical disease” or an “emerging infectious disease”. But dengue is far from novel in Singapore, a tropical island-nation that has dealt with the disease for decades. This dissertation charts a previously …

Making biosecurity, making Mexico : an ethnography of biological invasion
… in three areas: invasive species control, emerging infectious disease research, and the use of transgenic organisms. I examine how conservationists working in Mexican settings - particularly on islands - alternately protect or exterminate the various life forms they encounter; how …

Host-pathogen interactions and conservation implications of snake fungal disease over broad geographical scales
Emerging infectious diseases represent a threat to biodiversity, posing significant challenges to wildlife conservation globally. Infectious diseases can cause population declines, local extirpations and, in rare cases, complete species extinction. Among emerging pathogens, pathogenic fungi have …

Long-term Consequences of West Nile Virus in Virginia.

THE ABUNDANCE AND INFECTION STATUS OF ANOPHELES spp. MOSQUITOES AT THREE SITES IN LOUDOUN COUNTY, NORTHERN VIRGINIA
Malaria is a re-emerging infectious disease with approximately half of the world's population at risk. In the US, since the 1950’s the Center for Disease Control (CDC) has been reporting between 1,000 and 1,500 cases of malaria every year. A majority of these cases were among US travellers and were …

From Sample to Answer: Innovations in sample processing and CRISPR-based diagnostics for enhanced clinical translation and field deployment
The recent (re)emergence and rapid spread of infectious disease agents underscore the urgent need for effective disease prevention and control strategies. Accurate and timely diagnostics serve as the base for effective disease management, enabling the rapid identification of disease outbreaks, …

Developing a Novel, Safe, and Effective Platform for Generating Flavivirus Vaccines
… can cause a range of neurological or hemorrhagic diseases. The ongoing epidemics of flaviviral disease consistently demonstrate the need for new vaccines capable of outbreak control. However, safe, effective, and easy-to-produce vaccines remain relatively elusive due to limitations of conventional …

Identifying patterns and processes of sex-biases for an emerging fungal disease of wildlife
… changes have facilitated an increase in emerging infectious diseases, threatening biodiversity globally. Identifying the individuals, species, or communities most vulnerable to disease can guide the development of conservation priorities. Processes that structure individual variation, …

The evolution of virulence in Candida auris determined through experimental, ecological and epidemiological approaches
Candida auris is an emerging human fungal pathogen that has rapidly transitioned from its first description in a case of ear infection in Japan in 2008 to a global public health threat featuring the spread of six clades across six continents. Major problems concerning its management include: (i) …

Shifting disease dynamics following the invasion of an emerging wildlife pathogen
… also the species that experience the most severe disease and greatest mortality, which reduces their contribution over time. Additionally, I found that pathogen growth rates and the harm the pathogen causes to hosts has declined since the introduction to North America. I also observed high …
