In the study, there …

A Novel Custom-Made External Fixator For Treating Femur Fractures In Goats, Hsu-Hsun Lee, Ting-Sheng Lin, Lee-Shuan Lin, Cheng-Shu Chung, Shyh-Shyan Liu, Huan-Yu Hsu, Ching-Hou Ma, Jai-Wei Lee

The Thai Journal of Veterinary Medicine

External fixation is commonly used to treat long bone fractures in goats. It provides good enough stabilization on fractures to improve healing, minimizes soft tissue injury and only causes mild obstruction of the blood supply around the wounds. However, the large size and heavy weight of traditional external fixators (TEFs) cause them leave something to be desired. In this study, the feasibility of a novel custom-made external fixator (CMEF) for treating femoral fractures in goats was evaluated. Three one-year-old Anglo-Nubian female goats were subjected to experimental femoral fractures to their left femur with a CMEF installed for fixation. To evaluate …

Brown Treesnake Mortality After Aerial Application Of Toxic Baits, Scott M. Goetz, Eric T. Hileman, Melia G. Nafus, Amy A. Yackel Adams, Amanda R. Bryant, Robert N. Reed, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

Quantitative evaluation of control tools for managing invasive species is necessary to assess overall effectiveness and individual variation in treatment susceptibility. Invasive brown treesnakes (Boiga irregularis) on Guam have caused severe ecological and economic effects, pose a risk of accidental introduction to other islands, and are the greatest impediment to the reestablishment of extirpated native fauna. An aerial delivery system for rodent‐based toxic baits can reduce brown treesnake abundance and heterogeneity among individuals may influence bait attraction or toxicant susceptibility. Previous baiting trials have either been simulated aerial treatments or relied on slightly different bait capsule compositions and the results …

Maxwell H. Gluck Equine Research Center Faculty Publications

Terpenes are naturally occurring compounds produced by plants that are of great commercial interest in the food, agricultural, cosmetic, and pharmaceutical industries due to their broad spectra of antibacterial, antifungal, anthelmintic, membrane permeation enhancement, and antioxidant biological activities. Applications of terpenes are often limited by their volatility and the need for surfactants or alcohols to produce stable, soluble (non-precipitated) products. Yeast particles (YPs) are hollow, porous microspheres that have been used for the encapsulation of terpenes (YP terpenes) by passive diffusion of terpenes through the porous YP cell walls. We here report the development of a second generation YP encapsulated …

Publications and Research

Background: The study objective was to examine cat owner ectoparasiticide purchases in the United States and estimate the impact of purchase gaps on timely ectoparasite protection administration. These purchase gaps lead to periods of time when cats are unprotected from ectoparasites.

Methods: Ectoparasiticide purchase transactions for individual cats from 671 U.S. veterinary clinics from January 1, 2017 through June 30, 2019 were evaluated to determine time “gaps” between doses of ectoparasiticides purchased in a defined 12-month period. Ectoparasiticides examined were topically applied products that contained fluralaner, fipronil/(S)-methoprene/pyriproxyfen, imidacloprid/pyriproxyfen or selamectin as active ingredients. The duration of protection following administration of …

Landscape Genetics Of American Beaver In Coastal Oregon, Clinton W. Epps, Vanessa M. Petro, Tyler G. Creech, Rachel S. Crowhurst, Matthew J. Weldy, Jimmy D. Taylor

United States Department of Agriculture Wildlife Services: Staff Publications

American beaver (Castor canadensis) have been translocated for population restoration, reduction of human‐wildlife conflict, and enhancement of ecosystem function. Yet few studies have assessed dispersal of beaver, making it difficult to determine at what scale translocations are appropriate. Genetic studies can provide inferences about gene flow, and thus dispersal. We used a landscape genetic approach to evaluate whether landscape features influenced gene flow among beaver in the Coast Range of western Oregon, USA, using samples collected April–September 2014. We collected genetic samples from live‐captured (n=232), road‐killed (n=2) and trapper‐provided (n=58) tissue samples and genotyped them at 10 microsatellite loci. We …

United States Department of Agriculture Wildlife Services: Staff Publications

Overpopulation of free-roaming cats is a major problem leading to negative impacts on animal health and welfare, public nuisance, transmission of zoonotic diseases, and well-documented harm to wildlife. Surgical sterilization had failed to provide a practical solution to free-roaming cats’ overpopulation under field conditions; therefore, efficient and safe non-surgical immunocontraception methods are aspired. Rabies is a deadly virus that may infect people and animals. However, the safety and efficacy of combined vaccination with anti-GnRH and rabies vaccines in feral cats, which often suffer from disrupted health conditions and experienced high stress level, has never been studied. Therefore, our objective was …

Schultz-Werth Award Papers

Porcine reproductive and respiratory syndrome virus (PRRSV) is an RNA virus which belongs to the family Arteriviridae. Since its emergence in the late 1980’s and early 1990’s, PRRSV has had a major economic effect on the swine industry. The most notable effects of this disease are respiratory distress in piglets and late-term pregnancy failures in sows. To track and control spread of this disease, the industry must be able determine which animals have been naturally infected with PRRSV as this contributes to major disease outbreaks and localized pandemics. While vaccines help control the spread of a disease, they also …

Use Of 3d-Printed Surgical Spoons Compared To Other Cystotomy Methods In Dogs, Davina D'Angelo

Animal Science Undergraduate Honors Theses

Bladder stones, also known as uroliths, are not an uncommon condition in domestic dogs. To remove these uroliths, which occur in various sizes, shapes, and compositions, veterinarians will perform a surgical procedure called a cystotomy. A cystotomy consists of creating a small incision into the lumen of the urinary bladder and the utilization of various methods to extract the uroliths. For general veterinary practitioners, the laparoscopic-assisted technique is unavailable. As a result, the methods available for urolith extraction are often limited to flushing the stones out by inserting a urinary catheter through the urinary tract and the use of off-label …

Component Causes Of Infectious Bovine Keratoconjunctivitis - The Role Of Moraxella Species In The Epidemiology Of Infectious Bovine Keratoconjunctivitis, John Dustin Loy, Matthew Hille, Gabriele Maier, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

Moraxella bovis can cause infectious bovine keratoconjunctivitis (IBK).

The role of M bovoculi in IBK is not fully understood.

M bovis and M bovoculi appear to undergo genetic recombination with each other or other members of the Moraxellaceae.

Recombination complicates their classification and potential role(s) in IBK pathogenesis.

MALDI-TOF MS is used to identify M bovis, 2 major strains or genotypes of M bovoculi, M ovis, and other members of the Moraxellaceae.

Classification and determination of pathogenesis potential within Moraxella species may be better understood through whole genome sequencing.

Comparative Study Of Anesthesia’S Effect On Baroreceptor Reflex And Sympathetic Nerve Activity In Adult Rats, John Harbin

Undergraduate Honors Theses

Anesthesia affects the central nervous system and can suppress cardiovascular activity. In this study, we compared two anesthetics, urethane and alpha-chloralose, to better understand their effect on sympathetic control of blood pressure, as well as how they would affect baroreceptor response and blood pressure in adult rats. To do this we performed baroreceptor tests in adult rats under isoflurane anesthesia and then either urethane (I.V. 1.25 g/kg, n=2) or alpha-chloralose (100 mg/kg, n=2). We found that baroreceptor responses were not significantly different between urethane or alpha-chloralose anesthesia. However, significant depression of baseline blood pressure occurred under alpha-chloralose anesthesia compared with …

Compounded Gabapentin For Felines: Associated Metabolic Processes And Analysis Of Potency, Johnny Altwal

Student Scholar Symposium Abstracts and Posters

Pharmaceutical compounding provides pharmacists and clinicians the opportunity to create unique drug formulations that are better suited to a specific patient’s needs. This is especially prevalent in veterinary medicine where clinicians treat a variety of maladies in a large number of species, thereby requiring unique formulations to more easily deliver drugs to animals. Several examples of compounded veterinary formulations with sub-therapeutic potencies have been published, but none examine compounded gabapentin. Gabapentin is frequently compounded into an oral suspension for veterinary use from tablets or capsules for the purpose of pain management in felines and other small animals. The project’s goals …

Population Genomics Of Invasive Rodents On Islands: Genetic Consequences Of Colonization And Prospects For Localized Synthetic Gene Drive, Kevin P. Oh, Aaron B. Shiels, Laura Shiels, Dimitri V. Blondel, Karl J. Campbell, J. Royden Saah, Alun L. Lloyd, Paul Q. Thomas, Fred Gould, Zaid Abdo, John R. Godwin, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Introduced rodent populations pose significant threats worldwide, with particularly severe impacts on islands. Advancements in genome editing have motivated interest in synthetic gene drives that could potentially provide efficient and localized suppression of invasive rodent populations. Application of such technologies will require rigorous population genomic surveys to evaluate population connectivity, taxonomic identification, and to inform design of gene drive localization mechanisms. One proposed approach leverages the predicted shifts in genetic variation that accompany island colonization, wherein founder effects, genetic drift, and island-specific selection are expected to result in locally fixed alleles (LFA) that are variable in neighboring nontarget populations. Engineering …

A New All-Natural Wound Treatment Gel Shows Strong Inhibitory Activity Against Staphylococcus Aureus And Other Wound Pathogens, Tasha K. Nelson

Electronic Theses and Dissertations

Skin related injuries are some of the most dangerous forms of wounds. In addition to treating the wound itself, health care providers must be cautious of microbial infections. In this study, we evaluate a novel all-natural antimicrobial gel compound (AMG) designed to kill planktonic bacteria, penetrate bacterial biofilms, and accelerate wound healing. In -vitro experiments demonstrate that AMG is effective in inhibiting planktonic growth and biofilm development of eight common pathogens. LIVE/DEAD staining and confocal microscopy reveal that planktonic growth and three-dimensional structure of biofilms were significantly reduced. Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) was used to investigate a small …

The Effects Of Trace Mineral Supplementation On Performance, Health, And Carcass Quality Of At-Risk Mineral Deficient Feedlot Cattle, Tevan J. Brady

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Morbidity in feedlot cattle due to disease is a common economical loss for feedlot producers. Utah is not typically considered a ‘feedlot state’, but there are several producers in the southern part of the state that specialize in receiving at-risk cattle. These cattle are at-risk because they are coming from areas known to be mineral deficient. Areas such as the western US, are known to be deficient in several trace minerals important in immune response. Therefore, it is critical that producers have an adequate plan to decrease the negative effects that this has on economic viability of their beef operations, …

School of Veterinary and Biomedical Sciences: Faculty Publications

A naturally occurring bovine model with excess follicular fluid androstenedione (High A4), reduced fertility, and polycystic ovary syndrome (PCOS)-like characteristics has been identified. We hypothesized High A4 granulosa cells (GCs) would exhibit altered cell proliferation and/or steroidogenesis. Microarrays of Control and High A4 GCs combined with Ingenuity Pathway Analysis indicated that High A4 GCs had cell cycle inhibition and increased expression of microRNAs that inhibit cell cycle genes. Granulosa cell culture confirmed that A4 treatment decreased GC proliferation, increased anti-Müllerian hormone, and increased mRNA for CTNNBIP1. Increased CTNNBIP1 prevents CTNNB1 from interacting with members of the WNT signaling pathway thereby …

Detecting Dna Oxidation In Sperm, Alexie Zwerdling

Student Research Symposium

Declining body-wide levels of nicotinamide adenine dinucleotide (NAD) that are present in normal aging men are linked to decreased sperm quality and DNA integrity. When NAD is low, the amount of oxidative stress on the DNA appears to be increased, due to the limited regeneration of the antioxidant glutathione, which is NAD-dependent. We therefore hypothesize that the increased sperm DNA damage in the aging male is caused by an elevated formation of 8-oxoguanine in the DNA, caused by increased oxidative stress when NAD levels are low. To test this hypothesis, a transgenic mouse model (ANDY mouse) was used to create …
