Accurate Simulation Of Reads And Improved Strategies For Abundance Estimation Supporting Reduced Representation Sequencing For Metagenomics, Ryan Kuster
Doctoral Dissertations
Next generation sequencing has impacted all areas of biology by providing affordable investigations into some of the most complex processes underpinning life. With its ubiquitous application, there is still benefit in considering the nuances of the technology and its downstream analysis. Sequencing libraries produced by fragmenting DNA with restriction enzyme digests limit the scope of sequencing to a reduced set of genomic loci, allowing for deeper sequencing of those regions at a reduced cost per sample. These sequencing libraries have been used to determine genetic markers within populations of closely related individuals due to their sensitivity and preservation within populations. …

Systematic Evaluation Of Database Builds In Metaproteomics For The Advancement Of Microbiome Research, Katherine E. Ostrouchov
Masters Theses
The microscopic life that inhabits a human shares a unique bond with its host. Microbes perform many functions that are vital to the survival of the human species and have long been shown to regulate the absorption of nutrients and to promote immune function. A lack of exposure to certain microbes early in life, excessive antibiotic usage, and improper diet can perturb human microbiomes and lead to disease. Since the emergence of omic sequencing technologies, it has now become possible to measure and monitor the genes and proteins made by these microorganisms to better understand how they contribute to host …
Rumen Biogeographical Regions And Their Impact On Microbial And Metabolome Variation, Macey P. Soltis
Rumen Biogeographical Regions And Their Impact On Microbial And Metabolome Variation, Macey P. Soltis
Masters Theses
The rumen microbiome is a complex microbial network critical to the health and nutrition of its host, due to their inherent ability to convert low-quality feedstuffs into energy. In rumen microbiome studies, the ventral sac is sampled from due to ease of access and repeatability. However, anatomical musculature demarcates the rumen into five sacs which may support distinct microbial communities. The distinction among the microbes may generate functional variation among the rumen microbiome, thus, specialized tasks within different sacs. The objective of this study was to determine the rumen liquid metabolome and epimural, planktonic, and fiber-adherent bacterial communities among each …

Multi-Omic Systems Biological Analysis Of Host-Microbe Interactions, Piet Jones
Doctoral Dissertations
Systems biology offers the opportunity to understand the complex mechanisms of various biological phenomena. The wealth of data that is produced, at an increasing rate, provides the potential to meet this opportunity. Here we take an applied approach to integrate multiple omic level data sources in order to generate biologically relevant hypotheses. We apply a novel analysis pipeline to model both, in concert, the microbial and transcriptomic signature from COVID-19 positive patients. We show patients may suffer from an increased microbial burden, with an increased pathogen potential. Gene expression evidence further shows patients may exhibit a compromised barrier immunity, owing …
