Impacts of multispecies parasitism on coho salmon (Oncorhynchus kisutch) in Oregon

Creator:: Ferguson, Jayde A.
Abstract:: Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

Evolution of a streamlined cooperator in Pseudomonas aeruginosa quorum sensing

Creator:: Huie, Jessica L.
Abstract:: Social behavior leading to the production of common goods is prone to exploitation. One such behavior in Pseudomonas aeruginosa is quorum sensing (QS), by which the bacteria produce signals to regulate extracellular common goods. Exploitation comes in the form of cheaters which have a mutation in the central quorum sensing...

Social Evolution and Regulatory Architecture of Pseudomonas aeruginosa Quorum Sensing

Creator:: Asfahl, Kyle L.
Abstract:: Cell-cell communication in bacteria is understood to facilitate the coordination of population-wide cooperative behavior in the form of concerted gene expression. The opportunistic pathogen Pseudomonas aeruginosa uses such a communication mechanism to regulate a large group of genes important to virulence strategies in this bacterium. This general mechanism of communication...

Quorum sensing gene regulation in Pseudomonas aeruginosa

Creator:: Gupta, Rashmi
Abstract:: Pseudomonas aeruginosa is an opportunistic human pathogen that infects immunocompromised individuals such as those suffering from burns or the genetic disorder cystic fibrosis. This organism utilizes a cell-cell communication mechanism known as quorum sensing (QS) to coordinate virulence gene expression and biofilm formation. It has three interconnected QS systems, namely...

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...

Analysis of salmonid leukocytes purified by hypotonic lysis of erythrocytes

Creator:: Crippen, Tawni L., Bootland, Linda M., Leong, Jo-Ann C., Fitzpatrick, Martin S., Schreck, Carl B., and Vella, Anthony T.
Abstract:: A technique that uses hypotonic lysis of erythrocytes was optimized for the purification of leukocytes from the peripheral blood and anterior kidney (pronephros) of rainbow trout Oncorhynchus mykiss. Comparisons of initial blood dilution (1:2, 1:4, and 1:6) and the time of exposure to hypotonic conditions (10, 20, and 40 s)...

Differential agar media for the identification of the Salmonella and Arizona groups of Enterobacteriaceae

Creator:: Stroup, John Raymond
Abstract:: Twelve differential agars have been studied in the development of media to presumptively identify the Salmonella Subgenera I-IV. Medium No. 7B/A (or Medium No. 7-H₂S Strip) combined the malonate, dulcitol, lysine decarboxylase and hydrogen sulfide reactions in one tube. It was designed to be used at the TSI stage of...

Photooxidative degradation of annual rye-grass straw to substrates enhancing rhodotorula mucilaginosa growth

Creator:: Park, Jerry Eugene
Abstract:: Annual ryegrass (Lolium multiflorum) is a major seed crop in the Willamette Valley of Oregon. Persistent crop diseases have necessitated annual field burning to protect future crops. This practice, while very effective for disease eradication, produces large quantities of air polluting smoke in the valley and a general wastage of...
