  • Yersinia ruckeri : a characterization of the carrier state in steelhead trout (Salmo gairdneri)

    Creator:
    Hunter, Valerie Antoinette
    Abstract:
    Fish, asymptomatically infected with Enteric Redmouth Bacterium (ERMB), were tested for their ability to transmit bacteria to non-infected fish. Unstressed carrier fish were unable to transmit enough bacteria to cause epizootics or produce carrier fish. However, when the ERMB carriers were stressed with heat, sufficient bacteria were shed to infect...

  • The Effects of Phytoplankton Prey Species and Nutrient Limitation on Microzooplankton

    Creator:
    McBeain, Kelsey Ann
    Abstract:
    Phytoplankton and microzooplankton comprise the base and the first link of the marine food web, respectively. These microbes are key drivers of marine carbon and nutrient cycles. Phytoplankton convert atmospheric CO₂ into organic carbon, and microzooplankton consume phytoplankton, packaging phytoplankton carbon into particulate forms that have a variety of fates:...

  • Structural and functional dissection of the vaccinia virus thymidine kinase enzyme

    Creator:
    Black, Margaret E.
    Abstract:
    Thymidine kinase is a key enzyme in the nucleotide salvage pathway, catalyzing the production of dTMP from thymidine and ATP. In order to identify the structural features of the TK protein and/or primary amino acid sequences which contribute to the catalytic and regulatory activities of this enzyme, an in vitro...

  • Development of mucosal vaccines for avian influenza A virus composed of recombinant Lactococcus lactis and Streptococcus gordonii

    Creator:
    Reese, Kaleb A.
    Abstract:
    Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...

  • Substrate capture by a psychrophilic marine bacterium

    Creator:
    Geesey, G. G.
    Abstract:
    Cells of the marine bacterium, Ant-300, accumulate loosely bound amino acids during amino acid uptake. The fraction of amino acid taken up that exists in the loosely bound state depends on the substrate in question. Shock treatment studies indicate that, in general, the initial binding, uptake, and retention of amino...

  • Establishment of an in vitro System for Studying Mycobacterium avium Protein Secretion

    Creator:
    Chinison, Jessica J.
    Abstract:
    Cases of pulmonary diseases caused by Mycobacterium avium complex (MAC) have increased over the years and have become a major health concern in Europe, Asia, and the United States. MAC, comprised of M. avium species and M. intracellulare, are found everywhere in the environment: in water sources and the soil....

  • The role of Salmonella typhimurium type three secretion system (T3SS) and effector proteins in chromatophore cell response.

    Creator:
    Farhad, Mohammad
    Abstract:
    Bacterial contamination of food poses a great risk to human health worldwide. A chromatophore cell-based biosensor, utilizing B. splendens erythrophore cells, is an emerging technology that has shown potential to detect bacterial toxicity based on function-dependent mechanisms. Previous studies have investigated the response of erythrophore cells to foodborne pathogens, pesticides,...

  • Harnessing Heterogeneity in Human Gut Microbiome Data

    Creator:
    Tataru, Christine
    Abstract:
    The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

  • Coliphage T3 S-adenosylmethionine hydrolase : properties of the cloned gene and consequences of its expression in Escherichia coli

    Creator:
    Hughes, Jeffrey A.
    Abstract:
    To begin the development of a research tool for use in the in vivo study of S-adenosylmethionine (SAM) metabolism, I attempted to locate, isolate, clone and elicit the expression of the SAM hydrolase gene (E.C. 3.3.1.2) of the coliphage T3. The gene was isolated and cloned into the M13mp8 cloning...

    Creator:
    Dierksen, Karen P.
    Abstract:
    Lactococcus lactis subsp. cremoris Ropy 352 and L. lactis subsp. cremoris Hollandicus produce an exopolysaccharide (EPS) that imparts commercially desirable textural and rheological properties to fermented milk products. This ropy phenotype is expressed under specific environmental conditions. A mucoid EPS phenotype, also expressed under specific environmental conditions, but not involved...
