  • Cooperation and conflict in Pseudomonas aeruginosa quorum sensing

    Creator:
    Wilder, Cara N.
    Abstract:
    Pseudomonas aeruginosa is an environmental bacterium as well as an opportunistic pathogen that primarily infects immunocompromised individuals, including those suffering from cystic fibrosis. The density-dependent regulation of gene expression via cell-to-cell communication, also termed quorum sensing (QS), is an important virulence determinant in this organism. Generally, P. aeruginosa uses three...

  • Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

    Creator:
    Collart, Lindsay P.
    Abstract:
    Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

  • Fecal Bacteroidetes host distributions and environmental source tracking

    Creator:
    Dick, Linda K.
    Abstract:
    Contamination of recreational and shellfish waters with fecal pollution is a major water quality issue with associated economic impacts and human health risks. Reliable fecal source identification and rapid, quantitative analyses are essential components of risk assessment. Enteric bacteria that are endemic to specific hosts have a potential role as...

  • 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...

  • Harnessing Heterogeneity in Human Gut Microbiome Data

    Creator:
    Tataru, Christine
    Abstract:
    The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....
