The Social Interactions of Pseudomonas aeruginosa

Creator:: Smith, Parker
Abstract:: Pseudomonas aeruginosa is a ubiquitous environmental microbe, opportunistic pathogen, and a highly social organism. P. aeruginosa utilizes a wide array of cooperative behaviors to adapt to the environmental conditions around it. These behaviors include quorum sensing (QS), a form a cell-to-cell signaling that coordinates the expression of secreted products in...

Expanding Diagnostic Assays for Pseudoloma neurophilia & Description of the Progression of Infection in Adult Zebrafish Populations

Creator:: Schuster, Corbin J.
Abstract:: Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Investigating the Impact of the Gut Microbiota on Rodent Behavior and their Interaction with Enteroendocrine Cells

Creator:: Singla, Priyanka
Abstract:: Gut-brain communication consists of bidirectional routes between cognitive centers of the brain and peripheral intestines. This bidirectional communication is the result of the interplay between enteroendocrine cells (EECs), enteric nervous system, central nervous system, the vagus nerve, and our microbiota. Multiple studies have associated gut microbial dysbiosis with neurological disorders...

What Makes a Fish Resistant? Comparative Genomics and Transcriptomics of Oncorhynchus mykiss with Differential Resistance to the Parasite Ceratonova shasta

Creator:: Barrett, Damien E.
Abstract:: The myxozoan Ceratonova shasta is an intestinal parasite of salmon and trout that causes ceratomyxosis, a disease characterized by severe inflammation of the intestine that can lead to hemorrhaging, necrosis, and death of the fish host. The parasite is endemic to the Pacific Northwest of the United States and Canada,...

Spatiotemporal Distribution of Ceratonova shasta and its Genotypes in the Deschutes River Basin

Creator:: Hubbard, Kalyn M.
Abstract:: The waterborne, myxozoan parasite Ceratonova shasta is endemic to the Pacific Northwest and can be lethal to its secondary salmonid host, including the culturally, economically, and recreationally important spring Chinook salmon (Oncorhynchus tshawytscha) of the Deschutes River, OR. Previously described genotypes of C. shasta exhibit specificity with their salmonid hosts....

The Role of the Mucosal Immunoglobulin IgT and Inflammatory Cytokines in Ceratonova shasta Infections in Rainbow Trout

Creator:: Taggart-Murphy, Laura M.
Abstract:: The myxozoan parasite Ceratonova shasta threatens both juvenile and adult salmonid populations in the Pacific Northwest region of the United States, causing intestine necrosis and hemorrhaging, along with high mortality in some fish strains. It induces an inflammatory tissue response in susceptible strains of fish; understanding the interactions between C....

Host-pathogen Interactions of Respiratory RNA Viruses and the Application of Recombinase Polymerase Amplification for Viral Diagnostics

Creator:: Prescott, Meagan A.
Abstract:: Humans and viral disease are inextricably intertwined. Viral disease plays an immeasurable role in human life, from the disease and economic burden associated with every facet of contending with human viral disease, to managing the consequences of viral disease in organisms important to our food supply, economy, and entertainment. The...

The Fitness Costs and Regulatory Strategies of Cooperative Siderophore Production in Pseudomonas

Creator:: Sexton, David
Abstract:: Cooperative behaviors in bacteria are increasingly appreciated for their relevance to microbial ecology and utility as model systems for social evolution. One example is the secretion of siderophores, a structurally diverse group of compounds that chelate extracellular iron. Siderophore production is considered cooperative because the benefits can be shared with...

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...

Transcriptome Responses of the Nitrifying Bacteria Nitrosomonas europaea and Nitrobacter hamburgensis to Low Oxygen

Creator:: Dobie, Michael
Abstract:: Nitrification is the process within the global Nitrogen Cycle where ammonia (NH3) is oxidized to nitrate (NO₃⁻) and can be carried out by two distinct groups of bacteria. The ammonia-oxidizing bacteria (AOB) first oxidize NH₃ to nitrite (NO₂⁻), and second, the nitrite-oxidizing bacteria (NOB) oxidize NO₂⁻ to NO₃⁻. In aerobic...
