Influence of iron concentration on the expression of the ferripyoverdine receptor gene FpvAIIb of Pseudomonas aeruginosa

Creator:: Glover, Rochelle and Schuster, Martin
Abstract:: Pseudomonas aeruginosa is an environmental bacterium which opportunistically infects humans. Commonly residing in irondepleted environments, P. aeruginosa uses iron-chelating molecules called siderophores to scavenge iron from its environment. The most prevalent siderophore used by P. aeruginosa is known as pyoverdine. After the cell synthesizes and secretes pyoverdine, the molecule binds...

Insight into the regulation of quorum sensing antiactivator genes qteE and qslA in Pseudomonas aeruginosa

Creator:: Lawless, Finn
Abstract:: Ubiquitous pathogen Pseudomonas aeruginosa coordinates population-wide activation of virulence genes through quorum sensing (QS), where individuals transition from solo to social behaviors to benefit the population. QS is complex and mechanisms vary from species to species, but the concept is common to the bacterial world and has implications in various...

Studies on the evolution and expression of the Type II ferripyoverdine receptor gene fpvAIIb in Pseudomonas aeruginosa

Creator:: Glover, Rochelle
Abstract:: When iron levels are low, the opportunistic pathogen Pseudomonas aeruginosa secretes the high-affinity iron-binding siderophore pyoverdine. The cognate ferripyoverdine receptor, FpvA, has gained attention as the most divergent gene in the organism’s genome, showing substantial evidence of positive selection. S-type pyocins, bacteriocins with specificity to Pseudomonads, enter cells through FpvA...

Study on the Evolution and Expression of the Pyoverdine Receptor FpvA inPseudomonas aeruginosa

Creator:: Singh, Amandip
Abstract:: Pseudomonas aeruginosa is a ubiquitous gram-negative bacterium that is capable of causing infections in people who are immune compromised. The bacterium can live in a variety of environments due to the variety of virulence factors it can produce. It is well adapted to living in iron-stringent conditions because it can...

Strain construction to test the significance of antiactivation in Pseudomonas quorum sensing

Creator:: Goff, Shannon Elise
Abstract:: The quorum sensing regulatory pathway has been extensively studied for its impact on the virulence of Pseudomonas aeruginosa, an opportunistic pathogen that causes acute and chronic infections in immunocompromised individuals such as those suffering from the genetic disorder cystic fibrosis. Part of the quorum sensing pathway that has not been...

Characterization of Quorum-Sensing Diversity in Environmental Pseudomonas aeruginosa Populations

Creator:: Grellmann, Elise Kaylene
Abstract:: While the quorum-sensing (QS) diversity of the opportunistic pathogen Pseudomonas aeruginosa has been well established in cystic fibrosis (CF) lung infections and in vitro experiments, little is known about its QS-diversity in natural environments. One significant QS-deficient behavior is social cheating. Social cheaters contain mutations that prevent them from producing...

Playing by the Rules: A Formal Specification of BoGL’s Loops and Type System

Creator:: Grejuc, Alex
Abstract:: BoGL is a programming language created for the purpose of computer science education that is specific to the domain of board games. Although there is a language grammar and an existing implementation that is currently used by students, a complete and formal language standard does not yet exist. In the...

Laboratory studies of growth conditions of Vibrio parahaemolyticus in Pacific oyster (Crassostrea gigas) with international considerations to shellfish-associated illnesses in South Korea

Creator:: Lee, Jeehye
Abstract:: Vibrio parahaemolyticus, a naturally occurring halophilic pathogen, is seasonally abundant in marine and estuarine environments. It is also the leading cause of gastroenteritis in humans world-wide. Numerous outbreak incidences associated with the pathogenic Vibrio parahaemolyticus contaminations in oyster products have raised public-health concerns as well as economic challenges to the...

Volatile Organic Compound Production in Synechococcus WH8102

Creator:: Ocel, Duncan R.
Abstract:: High-resolution mass spectrometry was used to measure a range of volatile organic compounds (VOCs) in real time as they were produced by the ubiquitous marine cyanobacterium Synechococcus WH8102 during a 24-hour light/dark cycle. Ethenone, acetaldehyde, ethanol, isoprene, acetic acid, dimethyl sulfide (DMS), acetone, phenol, and several as-yet unidentified compounds were...

Grapevine Leafroll associated Virus – 3 (GLRaV-3) Seasonal Titer Changes and Effects on Pinot Noir Fruit in Oregon

Creator:: Wright, Sarah K.
Abstract:: The Willamette Valley, west of the Cascade mountain range in the state of Oregon, is home to a growing number of vineyards. This rather recent, booming industry of the region has become an important component of the economy of the state’s agriculture since the late 1960’s, contributing more than $1.56...
