Bartonella And Y. Pestis Screening In Ctenophyllus Armatus Terribilis For Conservation Application For The America Pika (Ochotona Princeps) In The Rocky Mountain Front Range, Hilary Rinsland
Honors Theses
As temperatures continue to disproportionally increase in alpine regions due to climate change, parasite spillover from increased pika-rodent contact could bring new diseases to a susceptible alpine specialist, the American pika (Ochotona princeps). Fleas collected from pika at four alpine and subalpine study sites in Boulder County, Colorado from 2011-2017 were screened for Y. pestis and Bartonella using conventional PCR methods. This is the first study to detect Bartonella in the American Pika flea Ctenophyllus armatus terribilis and to propose the presence of B. grahmii in the alpine region of the Rocky Mountains.
Interactions Between Two Key Amphibian Defenses To Batrachochytrium Dendrobatidis In Panamanian Glass Frogs (Espadarana Prosoblepon), Andi Levorse
Honors Theses
Research on the amphibian pathogen Batrachochytrium dendrobatidis (Bd), the causative agent of the lethal disease chytridiomycosis, has advanced from assessments of pathogenicity and species susceptibility to more specialized questions concerning the complex interactions between the pathogen, species-specific immune responses, and the environment. Our work examines the potential for interactions between the two most important innate immune defenses of frogs against Bd: secretions of antimicrobial peptides and communities of commensal cutaneous bacteria. While both defenses have been studied individually, little data are available to examine interactions between these defenses. We conducted our study with field captured Panamanian glass frogs …
Community Structure Of The Microbiome Of Ixodes Scapularis In Relation To Sex, Stage, Lineage, And Geography, Christopher Lee Clark
Community Structure Of The Microbiome Of Ixodes Scapularis In Relation To Sex, Stage, Lineage, And Geography, Christopher Lee Clark
Honors Theses
This study sought to fill these gaps of knowledge ticks as a model species. Based on the known information on the microbiome of vectors, and ticks more specifically, I sought to answer two prominent questions: are there relationships between the microbiome of individual ticks and do ticks from different sexes or life stages have variance in their microbiomes? In reference to my first question, I hypothesized that ticks coming from the same lineage, being the males, 7 Community Structure of the Microbiome of Ixodes scapularis females, and resulting eggs, would have a more similar microbiome to each other than to …

Understanding The Structural Basis Of Sike Interactions, Alice Catalano
Honors Theses
Tank Binding Kinase 1 (TBK1) acts as a catalytic hub in the regulation of numerous immune signaling pathways. Suppressor of IκB Kinase ε (SIKE) was recently characterized as a substrate of TBK1 whose binding properties are modulated by phosphorylation state, but very little is currently known about its function. However, because SIKE is known to form a dimer with itself, previous work generated a list of potential SIKE partners based on other proteins that contain sequences homologous to SIKE. Here, computational models of four potential SIKE partners, Heavy Chain myosin, tubulin, Beta Catenin and Ezrin, were generated and docked with …
Characterizing Borrelia Burgdorferi In Virginia : Lyme Disease Prevalence As A Matter Of Bacterial Genetic Variation, Hannah Cornman
Characterizing Borrelia Burgdorferi In Virginia : Lyme Disease Prevalence As A Matter Of Bacterial Genetic Variation, Hannah Cornman
Honors Theses
yme Disease (LD) incidence and spatial distribution has grown dramatically in the past 20 years. In Virginia, the growth has been especially drastic, primarily in the Western part of the state. This research project investigates how genetic variability of the Lyme Disease causing bacteria, Borrelia burgdorferi, might be contributing to this increase in LD incidence in western Virginia. To do this, B. burgdorferi samples were isolated from ticks found across the state and were characterized by multilocus sequence typing (MLST). Phylogenetic and minimum spanning tree analyses were also performed. It was hypothesized that the increasing number of Lyme disease infections …
