United States Department of Agriculture Wildlife Services: Staff Publications

Chagas disease, a significant public health concern in the Americas, is caused by a protozoan parasite, Trypanosoma cruzi. The life cycle of T. cruzi involves kissing bugs (Triatoma spp.) functioning as vectors and mammalian species serving as hosts. Raccoons (Procyon lotor) and opossums (Didelphis virginiana) have been identified as important reservoir species in the life cycle of T. cruzi, but prevalence in both species in the southeastern United States is currently understudied. We quantified T. cruzi prevalence in these two key reservoir species across our study area in South Carolina, USA, and …

Pseudorabies virus (PRV)—the causative agent of Aujeszky’s disease—was eliminated from commercial pig production herds in the United States (US) in 2004; however, PRV remains endemic among invasive feral swine (Sus scrofa). The circulation of PRV among abundant, widespread feral swine populations poses a sustained risk for disease spillover to production herds. Risk–based surveillance has been successfully implemented for PRV in feral swine populations in the US. However, understanding the role of host genetics in infection status may offer new insights into the epidemiology and disease dynamics of PRV that can be applied to management strategies. Genetic mechanisms underlying …

The northern spotted owl (Strix occidentalis caurina; hereinafter NSO) was listed as “threatened” under the Endangered Species Act in 1990 and population declines have continued since that listing. Given the species’ protected status, any proposed activities on Federal lands that might impact NSO require consultation with U.S. Fish and Wildlife Service and part of that consultation often includes surveys to determine presence and occupancy status of the species in the proposed activity area. The objective of this report is to present study-area specific estimates of the probability of detection for NSO pairs from twelve 2-week seasonal survey periods …

Light Wavelength And Pulsing Frequency Affect Avoidance Responses Of Canada Geese, Ryan B. Lunn, Patrice E. Baumhardt, Bradley F. Blackwell, Jean Paul Freyssinier, Esteban Fernández-Juricic

United States Department of Agriculture Wildlife Services: Staff Publications

Collisions between birds and aircraft cause bird mortality, economic damage, and aviation safety hazards. One proposed solution to increasing the distance at which birds detect and move away from an approaching aircraft, ultimately mitigating the probability of collision, is through onboard lighting systems. Lights in vehicles have been shown to lead to earlier reactions in some bird species but they could also generate attraction, potentially increasing the probability of collision. Using information on the visual system of the Canada goose (Branta canadensis), we developed light stimuli of high chromatic contrast to their eyes. We then conducted a controlled …

Risk Of African Swine Fever Virus Transmission Among Wild Boar And Domestic Pigs In Poland, Kim M. Pepin, Tomasz Borowik, Maciej Frant, Kamila Plis, Tomasz Podgórski

United States Department of Agriculture Wildlife Services: Staff Publications

Introduction

African swine fever (ASF) is a notifiable disease of swine that impacts global pork trade and food security. In several countries across the globe, the disease persists in wild boar (WB) populations sympatric to domestic pig (DP)operations, with continued detections in both sectors. While there is evidence of spillover and spillback between the sectors, the frequency of occurrence and relative importance of different risk factors for transmission at the wildlife-livestock interface remain unclear.

Methods

To address this gap, we leveraged ASF surveillance data from WB and DP across Eastern Poland from 2014–2019 in an analysis that quantified the relative …

Changes In Fecal Glucocorticoid Metabolites In Captive Coyotes (Canis Latrans): Influence Of Gender, Time, And Reproductive Status, Eric M. Gese, Patricia A. Terletzky, Cole A. Bleke, Erika T. Stevenson, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

Simple summary

Biologists have long considered producing offspring a demanding time in the life of any animal, with reproducing and raising offspring being physiologically stressful. We examined whether breeding and producing pups was more stressful than other life-history stages among captive coyotes (Canis latrans) using fecal sampling and subsequent assays for glucocorticoid metabolites. Using 12 pairs of coyotes (five pairs produced pups, seven pairs did not), we examined fecal glucocorticoid metabolites (fGCM) covering 11 biological time periods for one year. We found high individual variability among both females and males with no apparent statistical effect of reproduction on …

Differential Canid Predation Of Translocated Juvenile Desert Tortoises (Gopherus Agassizii) Using Chemical Signature Differences, Derek B. Hall, Bruce A. Kimball, Jennifer M. Germano, Eric M. Gese, Jeanette A. Perry

United States Department of Agriculture Wildlife Services: Staff Publications

Differential predation was observed in a population of 59 translocated juvenile desert tortoises (Gopherus agassizii) of known sex during a juvenile translocation survival study between September 2012 and November 2017. The main source of mortality was attributed to coyote (Canis latrans) and kit fox (Vulpes macrotis) predation. Predation was skewed with higher female mortality than male mortality. We tested the hypothesis that juvenile females smell different than males, which leads to increased canid predation. We also explored differences in chemical signatures of resident adult female and male desert tortoises. We collected oral, cloacal, and …

Surveillance And Monitoring Of Amphibian Pathogens And Evaluating The Impacts Of An Associated Course-Based Undergraduate Research Experience (Cure), Jennifer Perez

EWU Masters Thesis Collection

Amphibians are a highly diverse class of vertebrates and crucial for natural ecosystems, inhabiting both aquatic and terrestrial environments at different life stages. However, amphibians are facing devastating declines largely due to the disease chytridiomycosis, caused by the fungal pathogens Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal). This disease can lead to population declines, biodiversity loss, and species extinction. However, resources to study and mitigate this disease are limited and an opportunity to assist in these efforts has been created in the form of a course-based undergraduate research experience (CURE). Chapter 1 of my thesis used Roger's Diffusion of Innovations …

Investigating Optimal Lipid:Protein Profiles For Infant Milk Formula, Valentina Ivanova

During the development of IMF, breast milk is commonly considered as the reference and IMF manufacturers are thriving to mimic the composition and/or to match the functionality of breast milk as closely as possible. A variety of bioactive ingredients, found in human breast milk, have been isolated and investigated for their potential functionality and utilised in the production of IMF. This study evaluated the current knowledge on compositional differences between human breast milk and IMF, and recent advances and developments in IMF production. Following …

Isolation And Characterisation Of Soil-Derived Bacteria With Antimicrobial Activity Against Antibiotic Resistant Pathogens, Ellen Twomey

Theses

Bacteriocins are a diverse range of ribosomally synthesized bioactive peptides, recognised predominantly for their potent antimicrobial activity against other strains closely related to the producer. The focus of this thesis was to explore this activity and examine the potential of bacteriocins to inhibit the growth of clinically relevant pathogens. Although evidence exists in the literature to suggest that bacteriocins could be applied in a similar fashion to conventional antibiotics, to date they are only utilised as preservative in food to prevent the growth of foodborne illness causing organisms. Isolating and screening bacterial strains in order to identify bacteriocin producers has …

Remote Justice & Domestic Violence: Process Pluralism Lessons From The Pandemic, Andrea K. Schneider, Heather Hlavka, Sameena Mulla, Erin Schubert, Aleksandra J. Snowden, Jennica Webster

Articles

Domestic violence procedures, like so many court processes around the world, were forced to go online and remote during the pandemic. The impact was dramatic-there were fewer restraining order petitions filed in the first place and an even lower amount granted. In short, domestic violence survivors, among the most vulnerable in our court system, were even more challenged in the last two years. Like many court systems, Milwaukee will never go back to being fully in-person for all procedures in conjunction with domestic violence. The evolving hybrid choices could provide additional access to justice, or these processes could create additional …

Muted Voices: United States Employees’ Role In Regulating And Protecting Workplace Health, James J. Brudney

Faculty Scholarship

The COVID-19 pandemic has given workplace health a higher profile, perhaps its highest since passage of the Occupational Safety and Health Act of 1970 (OSH Act). Increased visibility and public support are based on national awareness of how frontline essential (FE) workers risked their health and lives to protect fellow Americans and preserve economic stability. That said, the greater attentiveness to workplace health risks, and the heroism of FE workers, has been accompanied by what is at best a limited role for employee voice and participation in improving workplace protections. In a larger context, while unions have been heavily involved …

2-Aminopyridyl Functionalized Scaffold As A Tool For Systematic Investigation Of B-Glucan Binding And Dectin-1 Activation, Jasper Alinea Aquino

Graduate Student Theses, Dissertations, & Professional Papers

Tuberculosis (TB) – an infectious disease caused by Mycobacterium tuberculosis (Mtb) – remains an epidemic worldwide contributing to millions of deaths each year. Vaccination is possibly the best means of addressing this global threat. In recent years, synergistic Th1 and Th17 immune responses have emerged as the key players for a vaccine-induced protection against TB. There is currently no vaccine approved for humans that elicits a Th17-mediated immune response. C-Type Lectin Receptors (CLR), specifically Dectin-1, a pattern recognition receptor (PRR) of β-1,3-glucans (β-glucans) primarily from fungi cell walls, is known to induce a Th17-mediated response. The Th17 response upon binding …

Bacterial Pneumonia Associated With Multidrug-Resistant Gram-Negative Pathogens: Understanding Epidemiology, Resistance Patterns, And Implications With Covid-19, Dalal Hammoudi Halat, Carole Ayoub Moubareck

All Works

The ongoing spread of antimicrobial resistance has complicated the treatment of bacterial hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP). Gram-negative pathogens, especially those with multidrug-resistant profiles, including Escherichia coli, Klebsiella pneumoniae, Enterobacter spp., Pseudomonas aeruginosa, and Acinetobacter spp., are an important culprit in this type of infections. Understanding the determinants of resistance in pathogens causing pneumonia is ultimately stressing, especially in the shadows of the COVID-19 pandemic, when bacterial lung infections are considered a top priority that has become urgent to revise. Globally, the increasing prevalence of these pathogens in respiratory samples represents a significant infection challenge, with major limitations …

Transmission Competence Of B. Burgdorferi Infected Ixodes Ticks And Development Of An Ospc-Based Lyme Disease Vaccine, Samanta Kamalika

Theses and Dissertations (ETD)

Introduction. Lyme disease, otherwise called Lyme borreliosis, is a vector-borne infectious disease caused by the spirochete Borrelia burgdorferi (Bb). Studying the increase in overall Lyme disease incidence requires understanding the role of the vector Ixodes scapularis (I. scapularis) as the agent that carries the spirochete which is important to limit the occurrence of Lyme disease. Once we understand the vector-pathogen response, it also becomes important to determine the remedies for Lyme disease. Lyme disease can be treated with antibiotics if detected early, but the major obstacle lies in the early detection process. Therefore, it is important to investigate alternative preventive …
