  • Disease models and infectious phenotypes of Mycobacterium avium subspecies paratuberculosis

    Creator:
    Everman, Jamie L.
    Abstract:
    Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic inflammatory bowel disease that affects ruminant populations worldwide. The characteristic stages of the disease make diagnosis difficult, resulting in silent transmission among animals in a herd for years before proper detection of the infection. The extensive...

  • The conserved biology of herpesvirus latency : a study in cyprinid herpesvirus 3

    Creator:
    Reed, Aimee N.
    Abstract:
    Cyprinid herpesvirus 3 (CyHV-3), commonly known as koi herpesvirus (KHV), is a member of the Alloherpesviridae and is a deadly pathogen for koi and common carp, Cyprinus carpio. It causes severe gill necrosis and nephritis, dermal ulceration and hemorrhage, and mass mortality of up to 100% of affected fish. Fish...

  • What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

    Creator:
    Soffer, Nitzan
    Abstract:
    Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...

  • Aryl Hydrocarbon Receptor Activation and the Prevention of Type 1 Diabetes

    Creator:
    Newman, Matthew
    Abstract:
    The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that is an important regulator of immune responses in various disease models. In the non-obese diabetic (NOD) mouse model of type 1 diabetes, activation of this receptor leads to suppression of the autoimmune response and limits immune cell infiltration of...

  • Establishing Caenorhabditis elegans as a model for Mycobacterium avium subspecieshominissuis infection and intestinal colonization

    Creator:
    Ziaie, Navid
    Abstract:
    Mycobacterium avium subspecies hominissuis (MAH) causes potentially lethal opportunistic infections in immunocompromised individuals. Lack of a good animal model system currently hinders in vivo study of MAH virulence. Here we applied the tractable organism Caenorhabditis elegans (C. elegans), as a surrogate host to study the virulence of MAH. Worms were...

  • Investigation of Nematocyst Discharge in Parasitic Cnidarians (Myxozoa)

    Creator:
    Americus, Benjamin E.
    Abstract:
    Myxozoans are an enigmatic group of obligately parasitic, microscopic cnidarians. They diverged from their free-living relatives over 600 million years ago and have highly reduced genomes. However, they have retained nematocyst stinging cells which characterize the phylum Cnidaria. Free-living cnidarians utilize this cellular weaponry for defense and predation whereas the...

    Creator:
    McMinds, Ryan C.
    Abstract:
    The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

  • A Different Kind of Fatigue : A Cross-Cultural Analysis of the Etiology of Burnout in Medical Literature

    Creator:
    Tran, Jessica
    Abstract:
    The rate of physician dissatisfaction is steadily rising. Between 2011 and 2012, the number of physicians that would not choose a career in medicine if given the opportunity to decide again increased by 15% (Adams). This discontentment has major repercussions in the midst of the rising need for physicians: it...

  • How Do Parasites Infect Salmon? Comparative Transcriptomics Reveal Myxozoan Adaptations for Parasitism

    Creator:
    Americus, Benjamin
    Abstract:
    The phylum Cnidaria contains three main branches: Anthozoa (corals, sea anemones) Medusozoa (jellyfish, hydra), and Endocnidozoa. This latter branch is characterized by parasitism and contains the microscopic fish-parasites Myxozoa. Myxozoa are highly simplified, consisting of only a few cell types, however they have retained the nematocyst stinging cells and complex...

  • Advances in Freshwater Cyanobacterial Genomics

    Creator:
    Brown, Nathaniel M.
    Abstract:
    Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...
