  • 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...

  • 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...

  • Unlocking Water's Potential for Energy Storage: Abundant Materials for a Ubiquitous Problem

    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,...

  • Clostridium perfringens spores : inactivation, germination, and formation

    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,...

  • New Insights into the Molecular Mechanism of Clostridium perfringens Spore Germination

    Creator:
    Banawas, Saeed S.
    Abstract:
    C. perfringens is a spore-forming, gram-positive, anaerobic pathogenic bacterium capable of causing a wide variety of diseases in both humans and animals. However, the two most common illnesses in humans are C. perfringens type A food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) illnesses. Interestingly, these two major diseases are...

  • Characterization of Sporulation and Germination Genes in Clostridium perfringens

    Creator:
    Talukdar, Prabhat Kumar
    Abstract:
    Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that can produce as many as 17 different toxins and are responsible to cause a wide array of gastrointestinal (GI) and histotoxic diseases in humans and animals. As individual strains produce a subset of these toxins, C. perfringens strains can be classified...

    Deng, Kai
    Abstract:
    About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...
