Ecophylogenetic Characterization of the Gut Microbiome of At-risk Companion and Food Animals

Creator:: Kirchoff, Nicole S.
Abstract:: Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...

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,...

Immune response and protection against Streptococcus pyogenes after vaccination with Lactococcus lactis that expresses conserved region of M6 protein

Creator:: Mannam, Praveen
Abstract:: Most pathogens gain access to their host through mucosal surfaces. It is therefore desirable to develop mucosal vaccines that elicit an immune response to prevent this crucial first step in infection. Current mucosal vaccines are live attenuated strains of pathogens. More recent efforts have focused on the use of recombinant...

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:...

Role of Plc in the germination of Clostridium perfringens food poisoning isolate SM101

Creator:: Bond, Colton B.
Abstract:: Clostridium perfringens is the causative agent of gas gangrene and the 3rd most common cause of type A food borne disease in the United States. Critical to the pathogenicity of C. perfringens is the ability of this bacterium to produce highly resistant, metabolically dormant spores that can resume metabolic function...

Novel Experimental Designs and Mathematical Models to Study Fecal Indicator Bacteria Persistence in Surface Water

Creator:: Brooks, Lauren
Abstract:: High counts of fecal indicators, used to signal the potential presence of pathogens associated with untreated waste, result in the classification of water bodies throughout the United States as impaired. Nonpoint sources of unknown origin that contribute to fecal contamination make management of impaired waters challenging, as they are difficult...

Photosynthetic Energy Allocation Strategies of Thalassiosira pseudonana During Light Limited Growth

Creator:: Fisher, Nerissa L.
Abstract:: Photosynthetic energy allocation strategies were investigated in the marine diatom, Thalassiosira pseudonana, grown under a wide range of light limitation. Steady-state, continuous cultures were established at three light-limited growth rates. Simultaneous measurements of photosynthetic activity were made that targeted different points in photosynthetic energy flow from gross to net photosynthesis....

Growth and development of tetracycline resistant Chlamydia suis

Creator:: Lenart, Jennifer
Abstract:: Tetracycline is a front line antibiotic for the treatment of chlamydial infections in both humans and animals, and the emergence of tetracycline resistant (tet[superscript R]) Chlamydia is of significant clinical importance. Recently, several tet[superscript R] chlamydial strains have been isolated from swine (Sus scrofa) raised in production facilities in Nebraska....

Bacterial Predation in Host Microbiomes

Creator:: Welsh, Rory M.
Abstract:: In host-associated microbiomes, the mechanisms that regulate community composition or the principles that govern dynamics remain far from clear. However, understanding how the structure of microbial communities shift as the system moves away from a healthy state is critical to assessing disease progression and to formulate any potential mitigation strategy....

Factors affecting the Ceratomyxa shasta infectious cycle and transmission between polychaete and salmonid hosts

Creator:: Bjork, Sarah J.
Abstract:: Ceratomyxa shasta is a myxozoan parasite that infects salmonid fishes causing the disease ceratomyxosis that is characterized by severe hemorrhage and necrosis of the intestine and death of the fish host. Ceratomyxa shasta is endemic to the Pacific Northwestern United States and Canada, where epizootics are reported for both wild...
