  • Molecular mechanism of germination of Clostridium perfringens spores

    Creator:
    Paredes-Sabja, Daniel
    Abstract:
    Clostridium perfringens is the causative agent of a wide variety of diseases in animals and humans. C. perfringens can produce more than 15 toxins. However, individual strains produce a subset of these toxins. Although a small percentage of C. perfringens isolates (mostly belonging to type A) produce C. perfringens enterotoxin...

  • Seed and embryo development in pod culture of Phaseolus vulgaris and P. vulgaris x P. acutifolius

    Creator:
    Sabja, Ana Maria
    Abstract:
    Phaseolus vulgaris, the common bean, is susceptible to many bacterial, fungal and viral diseases. However, resistance to several diseases has been identified in related Phaseolus species, P. coccineus, P. acutifolius and P. lunatus. Thus, interspecific hybridization could result in transfer of beneficial characteristics. One of the problems encountered in interspecific...

  • Integration of Amino Acid Sequence and Alphafold2 Structural Predictions for Chlamydia trachomatis Polymorphic Membrane Proteins

    Creator:
    DeBrine, Abigail
    Abstract:
    Chlamydia trachomatis is an obligate intracellular bacterium that causes diseases of the eye and urogenital tract in humans. It is the cause of the sexual transmitted infection (STI) chlamydia, the most prevalent STI worldwide, and the ocular disease trachoma, the leading cause of infectious blindness. To date there is no...

  • Elucidating the Patterns of Cooccurrence, Spatial Structuring, and Impact on Fermentation Metabolism in Kombucha Microbial Communities

    Creator:
    Harrison, Keisha Rose
    Abstract:
    This dissertation investigates the microbial diversity and factors influencing the assembly of microbial communities in kombucha production, using a combination of 1H Nuclear Magnetic Resonance Spectroscopy, 16S and ITS rRNA metabarcoding, and traditional culture-based microbiological methods. It also explores the diversity of kombucha starter cultures through shotgun sequencing and metabarcoding...

  • Numerical Studies on Fluid-Structure Interaction and Applications

    Creator:
    Chen, Ming
    Abstract:
    Fluid-structure interaction (FSI) has been of significant research interest worldwide over the past several decades because of its variety of applications in both offshore and coastal engineering. Researchers analyzing FSI systems rely heavily on experimental tests in model scale in laboratories or large-scale sea trials. However, these tests are often...

  • The Primary Disease Gradient of Wheat Stripe Rust (Puccinia striiformis f. sp. tritici) Across Spatial Scales

    Creator:
    Farber, Daniel
    Abstract:
    Wheat stripe rust (WSR), also called yellow rust of wheat (Tricitum spp.), causal agent Puccinia striiformis f.sp. tritici (Pst), is a foliar disease of major economic importance on wheat, especially grown in temperate locations. WSR causes major losses of wheat yield, estimated at nearly $ 1 billion per year, and...

  • Inactivation of Clostridium perfringens in Meat Products

    Creator:
    Alnoman, Maryam M.
    Abstract:
    Clostridium perfringens type A strains are one of the main causative agents of gastrointestinal (GI) diseases in human and can cause both food poisoning (FP) and non-food-borne (NFB) diseases. Several factors contribute to the pathogenesis of C. perfringens type A strains including the wide presence of C. perfringens spores with...

  • The Inhibitory Activity of Essential Oil Constituents Against Clostridium perfringens Type A Isolates

    Creator:
    Alanazi, Saud
    Abstract:
    C. perfringens type A isolates are the causative agents of C. perfringens type A food poisoning (FP) and non-food-borne (NFB) human gastrointestinal diseases. In this study, we evaluated the antimicrobial effect of essential oil constituents (cinnamaldehyde, eugenol, allyl isothiocyanate (AITC), and carvacrol) against C. perfringens FP and NFB isolates grown...

    Creator:
    Leonard, Daniel P.
    Abstract:
    Water is an absolute necessity for life as we know it. It provides a useful medium in which chemical reactions take place that allowed for the development of single cellular organisms. When combined with the evolutionary accident that was pho- tosynthesis, water became not only a useful medium chemical reactions,...

    Creator:
    Udompijitkul, Pathima
    Abstract:
    The enterotoxin-producing Clostridium perfringens type A isolates are responsible for the third most common foodborne illness in the United States and can also cause non-foodborne human gastrointestinal (GI) diseases such as antibiotic- associated and sporadic diarrheas. Three important factors contribute to the ability of C. perfringens to cause GI diseases,...
