  • Characterization of the pathogenicity and phylogeny of members of the Rhodococcus genus

    Creator:
    Creason, Allison L.
    Abstract:
    Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

  • Biophysical analyses of peroxiredoxins and a partner reductase

    Creator:
    Hall, Andrea Renée
    Abstract:
    Peroxiredoxins (Prxs) are dominant peroxide-reducing enzymes with two important roles: they protect all organisms from oxidative damage induced by peroxides, and in eukaryotes, they participate in hydrogen peroxide signaling pathways. This dissertation presents studies aimed at the biophysical characterization of select Prxs and a Prx reductase to elucidate their structure-function...

  • Comparative genomics of Vibrio and characterizing microbial communities at a shellfish hatchery

    Creator:
    Delgado, Hanna
    Abstract:
    Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...

  • Biotransformation of 2,4,6-trinitrotoluene by ruminal organisms

    Creator:
    De Lorme, Marthah J. M.
    Abstract:
    2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...

  • Understanding chlamydial biology through genome sequencing and comparative genomics

    Creator:
    Jeffrey, Brendan
    Abstract:
    The human pathogen Chlamydia trachomatis displays different phenotypes between serovars both in vivo and in vitro. The study of chlamydial biology has been hampered by the lack of a tractable genetic system. Here, chlamydial isolates with known phenotypes as well as strains generated though recombination were fully sequenced to address...

  • TonB-dependent outer-membrane proteins of Pseudomonas fluorescens : diverse and redundant roles in iron acquisition

    Creator:
    Hartney, Sierra L.
    Abstract:
    Pseudomonas is a diverse genus of Gram-negative bacteria that includes pathogens of plants, insects, and humans as well as environmental strains with no known pathogenicity. Pseudomonas fluorescens itself encompasses a heterologous group of bacteria that are prevalent in soil and on foliar and root surfaces of plants. Some strains of...

  • Investigation of unique marine environments for microbial natural products

    Creator:
    Thornburg, Christopher C.
    Abstract:
    Metagenomics has revealed that the marine microbial biosphere is immensely more diverse than originally considered, and is an almost untapped reservoir for the potential discovery of microbial natural products. Despite numerous advances in culturing, biosynthetic engineering and genomic-based screening efforts to uncover much of this diversity in relatively accessible environments,...

  • Identification and characterization of type III effector proteins in plant-associated bacteria

    Creator:
    Thomas, William J.
    Abstract:
    Symbioses between microbes and multicellular eukaryotes are found in all biomes, and encompass a spectrum of symbiotic lifestyles that includes parasitism and disease, commensalism, and mutually beneficial interdependent host-microbe relationships. Regardless of outcome, these symbiotic lifestyles are governed by a complex molecular "courtship" between microbe and potential host. This courtship...

  • Bacterial pathogens and associated toxins involved in erythrophore cell aggregation

    Creator:
    Hutchison, Janine R.
    Abstract:
    Current detection methods for bacterial contamination rely on structure based detection of proteins and nucleic acids. While these methods are easy to use and reliable, they cannot evaluate the toxicity of a sample and the potential to cause disease. Previously, erythrophore cells derived from Betta splendens had been suggested as...

  • Genome-enabled investigation of the minimal growth requirements andphosphate metabolism for Pelagibacter marine bacteria

    Creator:
    Carini, Paul J.
    Abstract:
    Members of the SAR11 clade of heterotrophic α-proteobacteria are ubiquitous and abundant in the world's oceans where they are thought to play a pivotal role in the global carbon cycle. The first SAR11 bacterium cultivated in vitro, 'Candidatus Pelagibacter ubique' HTCC1062 (Ca. P. ubique), was isolated by dilution into sterile...
