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...

Analysis of chlamydial and host proteins associated with infection

Creator:: Chu, Hencelyn
Abstract:: Chlamydiae are obligate intracellular bacteria that infect a variety of eukaryotic hosts and affect normal host processes. Within host cells, their developmental cycle takes place inside non-acidified vacuoles termed inclusions. An inclusion membrane composed primarily of secreted chlamydial synthesized proteins called Incs encloses the inclusion. At this location, Incs have...

Comparing Sediment Microbial Communities of Arctic Beaver Ponds to Tundra Lakes and Streams

Creator:: Shannon, Kelly
Abstract:: In recent decades the habitat of North American beaver (Castor canadensis) has expanded from boreal forests into pan-Arctic tundra ecosystems. It is unknown how the advance of beavers into Arctic watersheds will impact microbial communities responsible for the mineralization of organic matter (OM), which has implications for carbon cycling. To...

The role of chlamydial inclusion membrane proteins in host-pathogen interaction and the development of novel methods for studying chlamydial biology

Creator:: Alzhanov, Damir T.
Abstract:: The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...
Resource Type:: Dissertation

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...
Resource Type:: Dissertation

Arsenic and Zinc Deficiency Induced Changes in Pancreatic Beta Cells

Creator:: Cao, Annie L.
Abstract:: Pancreatic beta cells produce and release insulin, a vital hormone that regulates blood glucose levels, and their dysfunction contributes to the development of diabetes mellitus. Dietary zinc deficiency and exposure to the toxicant inorganic arsenic have both independently been associated with diabetes, although the effects of their combination on pancreatic...
Resource Type:: Honors College Thesis

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...

Survival of fecal coliform bacteria in sludge-amended soils

Creator:: Hartel, Peter G.
Abstract:: A study was conducted to determine the effects or temperature, solar radiation, rainfall, and saturated flow on fecal coliform numbers in sewage sludge-amended soils. To determine this, four 4.6 X 13.7 m field plots were each amended in summer and in winter with 800 liters of anaerobically-digested sewage sludge, and...
