Analysis of Betta splendens erythrophore responses to Bacillus cereus cultured in different media

Creator:: Austin, Melissa J.
Abstract:: Biological agents and their products commonly cause foodborne illnesses. In the United States it is estimated that there are over 76 million cases of foodborne illnesses each year, resulting in an economic loss of approximately $40 billion. These high figures demonstrate the need for bioassays that display a rapid and...

The role of chlamydial inclusion membrane proteins in host-pathogen interaction and the development of novel methods for studying chlamydial biology

Creator:: Alzhanov, Damir T.
Abstract:: The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...

Exploring the cellular mechanisms of Cnidarian bleaching in the sea anemone Aiptasia pallida

Creator:: Perez, Santiago
Abstract:: Many members of the Phylum Cnidaria are mutualistic with unicellular dinoflagellates belonging to the genus Symbiodinium. Corals are the most widely recognized example of these associations due to their key ecological importance in coral reef ecosystems where they serve as the structural and trophic foundation of these rich ecosystems. Coral...

Structural studies of the antioxidant defense enzymes; copper, zinc superoxide dismutase and alkyl hydroperoxide reductase flavoprotein

Creator:: Roberts, Blaine R.
Abstract:: Oxygen derived radicals are involved in many aspects of life from aging and cell signaling to disease states as diverse as heart disease, diabetes, neurodegeneration and inflammation. Therefore, understanding the function of antioxidant defense proteins and the effects of oxygen derived radicals on protein function is essential to elucidate the...

Molecular and cellular characterization of the intracellular phenotype of Mycobacterium avium

Creator:: Early, Julie V.
Abstract:: Mycobacterium avium cause disseminated disease in immunocompromised people such as AIDS patients. Subsequent to crossing the intestinal epithelium, M. avium thrive within vacuoles in macrophages. The bacteria exhibit a different, more invasive, phenotype after being in macrophages compared to M. avium from laboratory conditions. We hypothesized that this intracellular phenotype...

Characterization of germinant receptors in Clostridium perfringens non-food-borne isolates

Creator:: Banawas, Saeed S.
Abstract:: C. perfringens is a Gram-positive, spore-forming, 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 . These two major diseases are...

Surface-exposed proteins in the pathogenesis of Mycobacterium avium subsp. hominissuis

Creator:: McNamara, Michael J.
Abstract:: Mycobacterium avium subsp. hominissuis (MAH) is a pervasive environmental bacterium that can cause opportunistic infections in humans. Among the most robust and hardy members of the Mycobacterium genus, M. avium can persist and thrive in a range of challenging environments, including many which place it in direct contact with humans....

Characterization of novel marine oligotrophic bacteria isolated from the Pacific Ocean : description of Marinivirgula fluito gen. nov., sp. nov., Marinivirgula obesa gen. nov., sp. nov. and Litincola parvulus gen. nov., sp. nov.

Creator:: Shin, Eun Jung
Abstract:: A new high-throughput culturing (HTC) method using a low nutrient heterotrophic medium (LNHM) has led to the isolation of many novel strains of oligotrophic bacteria from marine ecosystems. Four strains belonging to a single dade, HTCC2151, HTCC218OT, HTCC2178T and HTCC2188T, were isolated from the coast of Oregon by the HTC...

Syntheses and evaluation of putative enzyme inhibitor of isoprenoid biosynthesis

Creator:: Phaosiri, Chanokporn
Abstract:: The discovery of the methylerythritol phosphate pathway (the MEP pathway) as an alternate pathway for isoprenoid biosynthesis in some organisms including most bacteria, malarial parasites and plants, but not in animals, has stimulated extensive studies in this area. Research has revealed the potential of finding novel antibacterials, antimalarial drugs, and...

Characterization of an inhibitor ("6S") of infectious pancreatic necrosis virus (IPNV) in normal rainbow trout serum (RTS) and its effects on the virus

Creator:: Park, Kyoung Chul
Abstract:: The characteristics of an inhibitor of infectious pancreatic necrosis virus (IPNV) found in normal rainbow trout serum (RTS) were studied. The serum inhibitor had a molecular weight of approximately 150 kDa and was dependent on divalent cations, either Ca²⁺ or Mg²⁺. It was stable at temperatures up to 50°C and...
