Predicting Multi-trophic Consequences of an Emerging Disease
… species. In the southeastern US, laurel wilt disease (LWD) is impacting numerous species in the Lauraceae family, with the majority of cases observed on Persea borbonia, a common sub-canopy tree found in many Coastal Plain habitats. This species is also known to be the primary larval host of …

Maximum containment : the most controversial labs in the world
… new vaccines, diagnostics, and treatments for emerging infectious diseases, potential biological weapons, and to contribute to the nation's biodefense. These labs were not the first dramatic reaction to the threat of biowarfare and are in fact, one product of a long history of the country's …

Chemotactic and inflammatory responses to and recognition of Encephalitozoon spp. of microsporidia
Microsporidiosis is an emerging disease among immunocompromised individuals who often present with chronic diarrhea. The intracellular, eukaryotic parasites responsible for this pathology can often disseminate, causing multiorgan infections. Dissemination of these pathogens is believed to occur …

Evasion Of Innate Immunity By The Pathogen Coxiella Burnetii
… infects alveolar macrophages and causes the emerging disease Q fever. It uses a type IV secretion system (T4SS) to inject over 100 bacterial effector proteins into the host cytoplasm, which modulate many host cellular processes to form a replicative niche for the bacteria inside the cell. We …

Integrative Genomic Approaches for Plant Trait Discovery, Fungal Pathogen Identification and Taxonomy
… recovering pathogen genomes directly from diseased tissues, and inconsistent reference resources for fungal and oomycete identification. This dissertation integrates long-read sequencing, metagenomic approaches, and genome-based classification to address these limitations. First, long-read …

Genomic tools to investigate and characterise emerging and reemerging disease in aquatic invertebrates
Emerging and re-emerging diseases in aquatic invertebrates present significant challenges to global aquaculture, threatening food security, livelihoods, and ecosystem health. This thesis addresses critical knowledge gaps in the detection, characterisation, and management of aquatic invertebrate …

Limits of detection of Magnaporthe oryzae Triticum pathotype in wheat seed: implications for pathogen dissemination
Wheat blast is an emerging disease on wheat, caused by the seed-borne fungal pathogen Magnaporthe oryzae Triticum pathotype (MoT). The first objective of this research was to establish the detection threshold for MoT in infected wheat seeds as a function of sensitivity and specificity of a modified …

Inclusion body hepatitis as a primary disease in commercial broiler chickens
… has been occurring as an economically important, emerging disease of broiler chickens in several countries. Historically, IBH has been identified as a secondary disease, often associated with common immunosuppressive diseases. However, few studies have identified IBH as a primary disease with no …

Studies on Paphies australis (Mesodesmatidae) in Whangārei, Aotearoa New Zealand: an investigation into their declining health.
Disease outbreaks in marine species can have devastating consequences, including increasing host mortality, destabilising commercial production, altering ecosystem functioning, and jeopardising human health. A changing ocean climate is expected to increase host stress and the risk of disease …

Bacteriophage Endolysins: Anti-Infectives and Lysidiagnostics for the Post-Antibiotic ERA
… to prevent and treat bacterial infection and disease. Addressing these threats will require the development and application of novel therapeutics and clinical approaches. The focus of our research is on one such novel approach, the use of bacteriophage endolysins as diagnostic …

Documenting the Patterns and Ecological Impacts of a Densovirus on Melissa Blue Butterflies (Lycaeides melissa) and Beyond
… represent convenient systems in which to study disease. Descriptions of the ecology and evolution of entomopathogens are essential for applications in biological pest control, assessing the consequences of disease in beneficial species, or expanding on general knowledge of disease dynamics. …

Goss’s wilt and leaf blight of corn: chemical control, residue management and resistance
Goss’s wilt and leaf blight of corn has been a re-emerging disease in the United States. Caused by the bacterium Clavibacter michiganensis subsp. nebraskensis (Cmn), Goss’s wilt has been increasing in Illinois due to factors that include continuous maize rotations, reduced tillage which increases …

Vector-borne Disease Risk Assessment in Times of Climate Change: The Ecology of Vectors and Pathogens
… in the 21st century will support a spread of disease vectors and vector-borne diseases. Ectothermic arthropods make up the largest group of vectors. They usually cannot self-regulate their body temperatures and are therefore considered to be very sensitive to changing climatic conditions. The …

MONITORING OF LEISHMANIA TARENTOLAE AND LEISHMANIA INFANTUM IN SAND FLIES AND SYNANTHROPIC REPTILES OF NORTHERN ITALY: EMERGING EPIDEMIOLOGICAL SCENARIOS?
Vector-borne diseases represent one-sixth of all infectious diseases and cause over one million deaths annually. Insect vectors can transmit pathogenic viruses, bacteria, and parasites. Among parasitic infections, leishmaniases, caused by protozoan parasites of the genus Leishmania, rank second …
