Physiological And Behavioral Stress-Induced Responses Of Dogs During Veterinary Examinations, Jessica Ellen Vester

Honors Projects

This study investigated whether stress responsiveness in dogs is more significant when the owner is present or absent during a veterinary examination. The study consisted of two experimental groups: "owner absent" and "owner present." Both groups consisted of 25 dogs each, totaling 50 dogs observed. A veterinarian and veterinary assistant recorded the dog's behavioral and physiological stress responses. Each group's behavioral and physiological stress-induced responses were compared using a Fischer Exact test and an Analysis of Covariance. The findings showed that dogs whose owners are present during the veterinary examination display fewer stress responses than dogs whose owners are absent …

Effects Of Prenatal Pesticide Exposure On The Fetal Brain And Placenta Transcriptomes In A Rodent Model, Corina Lesseur, Kirtan Kaur, Sean D Kelly, Karen Hermetz, Randy Williams, Ke Hao, Carmen J Marsit, W Michael Caudle, Jia Chen

Faculty, Staff and Student Publications

Organophosphate and pyrethroid pesticides are among the most extensively used insecticides worldwide. Prenatal exposures to both classes of pesticides have been linked to a wide range of neurobehavioral deficits in the offspring. The placenta is a neuroendocrine organ and the crucial regulator of the intrauterine environment; early-life toxicant exposures could impact neurobehavior by disrupting placental processes. Female C57BL/6 J mice were exposed via oral gavage to an organophosphate, chlorpyrifos (CPF) at 5 mg/kg, a pyrethroid, deltamethrin (DM), at 3 mg/kg, or vehicle only control (CTL). Exposure began two weeks before breeding and continued every three days until euthanasia at gestational …

Identifying Limitations In Using Diagnostic Testing For Absorption Of Passive Maternal Immunity In Neonatal Beef Calves To Predict Pre-Weaning Disease, Alexis Charlotte Thompson

Theses and Dissertations

Calves are born agammaglobulinemic and rely on colostrum consumption for the transfer of maternal passive immunity. Calves that fail to absorb adequate amounts of maternal antibodies from colostrum are commonly referred to as having failed transfer of passive immunity (FTPI). The overall aim of this dissertation was to explore the usefulness of FTPI testing in neonatal beef calves to predict their risk for subsequent illness or death. The objectives were to evaluate the impact of FTPI on pre-weaning disease in beef and dairy calves, quantify and compare the variance in IgG concentrations measured by radial immunodiffusion and serum total protein …

Evolution And Epidemiology Of Channel Catfish Virus (Ccv), Arun Venugopalan

Theses and Dissertations

Channel catfish virus disease (CCVD) is the principal viral disease in the United States catfish industry. The CCVD is caused by channel catfish virus (CCV), with mortality reaching up to 100% in fingerlings. CCV is assigned taxonomically to the family Alloherpesviridae, genus Ictalurivirus, species Ictalurid herpesvirus 1 (IcHV-1). To date, virulence, immunogenicity, and genome plasticity of the CCV field isolates have not been investigated. Three genotypes of CCV (IcHV-1A, IcHV-1B, and BCAHV) were identified using restriction fragment length polymorphism (RFLP) analysis. Virulence assessment of three representative isolates of RFLP groups suggests that IcHV-1B (pooled survival [mean ± SE]: 58.3% ± …

Development Of Live Attenuated A. Hydrophila Vaccines And Understanding Of Macrophage-Aeromonas Hydrophila Interactions, Eda Ozdemir

Theses and Dissertations

Channel catfish farming is the largest aquaculture industry in the U.S., and virulent Aeromonas hydrophila is an important re-emerging bacterial pathogen of farmed catfish. A. hydrophila is ubiquitous in the aquatic environment and causes motile Aeromonas septicemia (MAS) in farmed catfish. A. hydrophila infection is challenging to treat due to rapidly progressive mass mortalities. Although florfenicol has been used in managing outbreaks, acute onset of anorexia, drug cost, and emergence of antimicrobial-resistant strains are significant concerns. Prevention of MAS by vaccination could be a promising approach, but a commercial vaccine is not available. Thus, it is critical to develop effective …

Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper

Theses and Dissertations

Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …

Gauging Clientele Knowledge On Alternative Methods Of Payment For Veterinary Services In Relation To Client Satisfaction, Olivia Hritzkowin

Honors College Theses

The following study focuses on the knowledge that veterinary clients possess surrounding alternative methods of payment for veterinary services and its relation to overall client satisfaction, as well as the prevalence of mental health crisis in veterinary professionals as it relates to client satisfaction. An in-depth analysis of online articles and journals was compared to the results of a survey of pet owners and veterinary professionals to obtain results for the study. The results of the analysis of online resources revealed that many pet owners are stressed about paying for veterinary care for their animal and that most are unprepared …

Canine Heartworm Infection And Prophylaxis Use Among Pet Caretakers From The Cumberland Gap Region Of Tennessee, Usa, Charles T. Faulkner

Faculty Other Scholarly Content

The prevalence of infection with canine heartworm (CHW), Dirofilaria immitis, continues to increase across the United States, regardless of the availability of effective and affordable prophylactic products. Current reports of CHW prevalence as estimated by the Companion Animal Parasite Council (CAPC) are thought to under-represent the true magnitude of the issue because pet dogs that do not receive regular veterinary care are often excluded. This study estimated the prevalence of CHW in pet dogs and associated prophylaxis use in pet dogs in the Cumberland Gap Region with a combined doorstep diagnostic testing approach and caretaker survey. Dogs tested (n = …

In-Service Education And The Provision Of Educational Materials To Improve Awareness Of Chronic Wasting Disease Management Efforts In Arkansas, Mary Claire Stewart

Animal Science Undergraduate Honors Theses

Chronic Wasting Disease (CWD) is a disease caused by an accumulation of misfolded prions throughout the nervous system. This disease affects animals within the Cervidae Family, which includes deer, elk, moose, and caribou. This disease is fatal and physical symptoms often do not materialize until the animal is near death. CWD has become an increasing issue in Arkansas since an elk (Cervus canadensis) in Newton County tested positive for CWD in 2016. Since then, the Arkansas Game and Fish Commission (AGFC) has worked with the University of Arkansas Division of Agriculture (UADA) and others to develop management strategies to slow …

Veterinary Access Barriers Experienced By Urban Versus Rural Clients: A Case Study In Middle America, Molly Andreasen

Theses/Capstones/Creative Projects

The comparison of urban versus rural clientele as to their access to veterinary care and preferences regarding veterinary services has received little research attention. A better understanding of client perspectives is critical for ongoing efforts to provide more equitable availability of veterinary services across varying demographic areas. In this study, I directly assess differences in access to veterinary services based on client perspectives from both rural and urban locales across Nebraska, USA, a state almost directly in the middle of America. It was expected that rural clients would experience more barriers to veterinary access in general and with respect to …

Emerging Tick-Borne Diseases In Northeast Tennessee, Jacob Schultz

Electronic Theses and Dissertations

Tick populations have been immigrating into northeast Tennessee from east Tennessee, Kentucky, Virginia, and North Carolina. Counties in states bordering northeast Tennessee harbor tick species associated with human illness. Human diseases transmitted by ticks include ehrlichiosis, spotted fever rickettsial group diseases, tularemia, anaplasmosis, babesiosis, Lyme disease, alpha-gal syndrome, Heartland virus, Powassan virus, and southern tick-associated rash illness (STARI). These diseases cause morbidity and mortality in human populations and may pose a high risk to individuals, wildlife, and livestock. The Cherokee National Forest covering the east Tennessee border provides a permissible environment for ticks to immigrate and thrive. Residents of northeast …

Optimal R&D Investment In The Management Of Invasive Species, William Haden Chomphosy, Dale T. Manning, Stephanie A. Shwiff, Stephan Weiler

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive alien species (IAS) threaten world biodiversity, ecosystem services, and economic welfare. While existing literature has characterized the optimal control of an established IAS, it has not considered how research and development (R&D) into new removal methods or technologies can affect management decisions and costs over time. R&D can lower the costs of control in a management plan and creates an intertemporal trade-off between quick but costly control and gradual but cheaper removal over time. In this paper, we develop and solve a continuous time dynamic optimization model to study how investment in R&D influences the optimal control of an …

The Mental Health Epidemic In Veterinary Medicine: An Analysis Of Burnout In The Veterinary Field, Hannah Eckstein

Undergraduate Theses

The Mayo Clinic describes burnout as a specific type of stress that involves a state of physical or emotional exhaustion. This exhaustion can lead to a lowered sense of accomplishment and negative personal identity. Despite burnout not being an actual diagnosis, many researchers believe there are several mental health components that contribute to burnout, such as depression and anxiety. Several factors are known to contribute to specifically work-related burnout, including lack of control, work-life imbalance, lack of social support, and extremes of the activity. All of the above factors relate to the veterinary field. In one study, 6.8% of male …

Regenerative Medicine For Tendon/Ligament Injuries: De Novo Equine Tendon/Ligament Neotissue Generation And Application, Takashi Taguchi

LSU Doctoral Dissertations

Tendon and ligament injuries are debilitating conditions across species. Poor regenerative capacities of these tissues limit restoration of original functions. The first study evaluated the effect of cellular administration on tendon/ligament injuries in horses using meta-analysis. The cellular administration was effective in restoring ultrasonographic echogenicity and increasing vascularity during early phase of healing. Additionally, it improved microstructural organization of healed tissue in terms of cellularity and fiber alignment. However, the study did not support its use for increasing rate of return to performance, expression/deposition of tendon-specific genes/proteins, or mechanical properties.

The findings led to the second study that engineered implantable …

The Effects Of Artificial Insemination On Beef Cattle In The United States, Allee R. Sweeten, Abigail Shelnut, Madison Dickey

ATU Scholars Symposium

Artificial insemination (AI) is a reproductive procedure widely used in cattle industries and other livestock to increase pregnancy rates. Breeders must wait until the animals are in the estrus part of their estrous cycle to AI. Estrus synchronization is utilized to manipulate the estrous cycle to go into estrus or standing heat. AI is conducted by loading a semen straw into an inseminating gun, inserting the gun into the vagina of the heifer, and making sure it gets past the cervix by palpating with the other hand. Once past the cervix, the semen can be distributed in the heifer. AI …

The Demographic Shift Of Males And Females In Veterinary Medicine, Dalton Tatum, Eddy Patterson, Mia C. Ratliff

ATU Scholars Symposium

The workforce in veterinary medicine saw a gender shift from a male dominated field towards women in the present day. This research aimed to determine why this shift occurred through demographic analysis and surveys to different job types in this career path. By using this data, the group determined that one of the biggest impacts of the shift is due to the very component that makes veterinary medicine such a tough field, and it is located at the graduate school entry level . The competitiveness level is intertwined through all of the data and leads to the conclusion that females …

Use Of A Clinical Skills Training Center To Supplement A Distributive Model Of Education In A Veterinary Technology Program, Megan Taliaferro

Inquiry: The Journal of the Virginia Community Colleges

A distributive model of education has recently become a popular method for training veterinary technicians in the United States. Although this model has significant benefits, such as decreased cost of program infrastructure, there are significant challenges in managing students and their clinical skill acquisition using private veterinary hospitals. A clinical skills training center was implemented at Tidewater Community College to address a main shortcoming of the distributive model, namely the lack of specialized training models at outside hospitals. Based on survey findings, both students and clinical mentors found the veterinary technology clinical skill training center to be a beneficial addition …

Assessing The Nutritional Value Of Dubia Roaches (Blaptica Dubia) As A Feeder Insect In Reptiles, Elise Barras

LSU Master's Theses

Dubia roaches (Blaptica dubia) have emerged on the market as a high protein and low-fat alternative to other feeder insects for captive reptiles. However, much like other insects, dubia roaches naturally have an inverse calcium to phosphorus (Ca:P) ratio. Offering insects to reptiles that are deficient in calcium can lead to nutritional disease (e.g., nutritional secondary hyperparathyroidism). For dubia roaches to be a valuable feeder insect, their Ca:P ratio must be corrected. Several studies have assessed their nutritional composition, but no studies have manipulated the calcium content of these insects. Using a high calcium (8.3% calcium, dry matter) …

School of Veterinary and Biomedical Sciences: Faculty Publications

The severe consequences of the Zika virus (ZIKV) infections resulting in congenital Zika syndrome in infants and the autoimmune Guillain–Barre syndrome in adults warrant the development of safe and efficacious vaccines and therapeutics. Currently, there are no approved treatment options for ZIKV infection. Herein, we describe the development of a bacterial ferritin-based nanoparticle vaccine candidate for ZIKV. The viral envelope (E) protein domain III (DIII) was fused in-frame at the amino-terminus of ferritin. The resulting nanoparticle displaying the DIII was examined for its ability to induce immune responses and protect vaccinated animals upon lethal virus challenge. Our results show that …

Cell-Specific Role Of Il4rα Signaling In Allergic Asthma, Ishita Choudhary

LSU Doctoral Dissertations

IL-4 and IL-13 play a critical role in allergic asthma pathogenesis via their common receptor, i.e., interleukin 4 receptor alpha (IL4Rα). However, the cell type-specific role of IL4Rα-mediated signaling in allergic asthma has remained unclear. We hypothesized that the role of IL4Rα signaling in allergic asthma is cell-type specific. To test our hypothesis, we challenged myeloid cell-specific IL4Rα-deficient (LysMcre^+/+/IL4Rα^fl/fl), myeloid cell-specific IL4Rα-sufficient (LysMcre^+/+/IL4Rα^wt/wt), airway epithelial cell-specific IL4Rα-deficient (CCSP-Cre⁺/IL4Rα^fl/fl), and airway epithelial cell-specific IL4Rα-sufficient (CCSP-Cre^-/IL4Rα^fl/fl) mice with either mixed allergens (MA) or normal saline three …

Effect Of Furosemide Administration On Plasma Analytes And Urine Enzyme Excretion In Two Reptilian Species, Kathryn Metcalf

LSU Master's Theses

Renal disease is a common ailment of captive reptiles that is often closely linked to chronic, subclinical states of dehydration. Currently, the diagnosis of renal disease in reptiles is poorly characterized and often relies on invasive diagnostic techniques (e.g., renal biopsy) for definitive diagnosis. A potential outlet for the further characterization of renal dysfunction in reptiles is the induction of dehydration by furosemide therapy. Furosemide is a loop diuretic that is commonly used in mammalian patients for the treatment of congestive heart failure. The utility of furosemide in reptiles is poorly characterized, however, both experimental and clinical utility of this …

Effects Of Pregnancy And Progesterone On Atrial Fibrillation, Heloisa M. Rutigliano

Browse all Datasets

Atrial Fibrillation (AF) is the most common cardiac arrythmia in adults with likely sex-specific risk factors. Female sex hormones may be important in modulating risk for atrial fibrillation. We hypothesize that pregnancy and progesterone (P4), a hormone found in high levels during pregnancy with abrupt withdrawal immediately after parturition, modulates AF susceptibility in female goats. Cardiac specific TGF-?1 transgenic female goats and age-matched wild-type (WT) female goats were utilized. Pacemakers were implanted in all animals for continuous arrhythmia monitoring and AF inducibility. AF inducibility was evaluated using 5 separate 10 s bursts of atrial pacing (160 - 200 ms). In …

Contribution Of The Microbiome On Reproductive Outcomes During Pregnancy, Kalie Beckers

LSU Doctoral Dissertations

A series of translational comparative studies were performed to investigate the effects of the maternal microbiome on reproductive function and outcomes. With the launch of the human microbiome project in 2007, the next generation sequencing of microbiomes is booming. It is not only in the human medicine field, but also in veterinary species. This study specifically investigates the fecal microbiome in blood pressure high sublime 5 (BPH/5) mouse model that spontaneously develops preeclampsia (PE) and obesity. Additionally, the equine reproductive tract microbiome was explored and compared to microbiome of other host body sites. The BPH/5 mouse is a translational model …

Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette

Honors College Theses

Cannabidiol (CBD) is a substance that has been used in complementary medicine for many years. However, modern medicine has little knowledge of how this substance is utilized and metabolized in ruminant animals. Regulations on quality assurance and use in animals are lacking, and CBD supplementation in livestock is not approved. If CBD supplements can be shown to be safe and effective, detection in the animal will be important for determining regulation of use. A withdrawal period can then be established to allow time for deterioration of product to safe levels before livestock products enter human markets. This study sought to …

"Barriers Between Client Education/Communication And Exotic Animal Husbandry", Caileigh M. Linton

Honors College Theses

The purpose of this study is to quantify the knowledge gap between clientele and veterinary staff about exotic animal husbandry corresponding to housing and diet specifically. With the rise of social media platforms and influencers, the spread of misinformation and stigma revolving around the mistrust of veterinary staff has created strife between clients and veterinary professionals. Misinformation influences pet owners to implement aspects of care into their pets lives that may be unnecessary or harmful. Consequently, as veterinary professionals attempt to educate their clients they are not always trusting of the information being provided to them. This can lead to …

Corticosterone Measurement In A Cryptosporidium-Positive Population Of Louisiana Pine Snakes (Pituophis Ruthveni), Corinne Mayer

LSU Master's Theses

Louisiana pine snakes (Pituophis ruthveni) are one of the rarest snake species in North America, and federally classified as “threatened” (United States Fish and Wildlife, 2018). Recent establishment of sustainable captive breeding populations combined with decades of field research by conservation biologists has led to several advancements in our knowledge of this species; however, further investigations into health parameters and the physiology of this species are needed to optimize management of captive populations.

One recent investigation highlighted the difficulties in reliably differentiating the sexes in P. ruthveni using traditional tail probing techniques (Katz et al., 2020). Prior to …
