Identity, Gender, And Tracking: The Reality Of Boundaries For Veterinary Students, Jenny R. Vermilya
Identity, Gender, And Tracking: The Reality Of Boundaries For Veterinary Students, Jenny R. Vermilya
New Directions in the Human-Animal Bond
Using in-depth interviews with veterinary students, Identity, Gender, and Tracking: The Reality of Boundaries for Veterinary Students explores the experience of enrollment in an educational program that tracks students based on the species of animals that they wish to treat. The identity of a veterinarian is one characterized by care; thus, students have to construct different definitions of care, creating a system of power and inequality. Tracking produces multiple boundaries for veterinary students, which has consequences not just for the veterinarian, but also for the treatment of animals. Written for administrators and students alike, Identity, Gender, and Tracking sheds light …

Babesiosis is a disease caused by tickborne hemoprotozoan apicomplexan parasites of the genus Babesia that negatively impacts public health and food security worldwide. Development of effective and sustainable vaccines against babesiosis is currently hindered in part by the absence of definitive host correlates of protection. Despite that, studies in Babesia microti and Babesia bovis, major causative agents of human and bovine babesiosis, respectively, suggest that early activation of innate immune responses is crucial for vertebrates to survive acute infection. Trained immunity (TI) is defined as the development of memory in vertebrate innate immune cells, allowing more efficient responses to subsequent …

Simple Summary: Myocarditis is the inflammation of the heart muscle, and viral infections are a common cause of this disease. Myocarditis in some patients can progress to dilated cardiomyopathy (DCM). The mouse model of coxsackievirus B3 (CVB3) is commonly used to understand this disease progression in DCM patients. In this paper, we have attempted to analyze antibodies for heart antigens that could be produced as a result of heart damage in animals infected with CVB3 using a technique called Phage ImmunoPrecipitation Sequencing (PhIP-Seq). The analyses led us to identify antibodies for several proteins that were not previously reported that may …

School of Veterinary and Biomedical Sciences: Faculty Publications
Coxsackievirus B3 (CVB3)-induced myocarditis is commonly employed to study viral pathogenesis in mice.Chronically affected micemaydevelop dilated cardiomyopathy, which may involve the mediation of immune and nonimmune cells. To dissect this complexity, we performed single-cell RNA sequencing on heart cells from healthy and myocarditic mice, leading us to note significant proportions of myeloid cells, T cells, and fibroblasts. Although the transcriptomes of myeloid cells were mainly of M2 phenotype, the Th17 cells, CTLs, and Treg cells had signatures critical for cytotoxic functions. Fibroblasts were heterogeneous expressing genes important in fibrosis and regulation of inflammation and immune responses. The intercellular communication networks …

Guanabenz In The Horse – A Preliminary Report On Clinical Effects And Comparison To Clonidine And Other Alpha-2 Adrenergic Agonists, Andreas F. Lehner, L. Dirikolu, Thomas Tobin
Veterinary Science Faculty Publications
In veterinary medicine, a number of alpha-2 receptor agonists are marketed as sedatives/hypnotics and analgesics, with their principal use being the chemical restraint of large and small animals. Guanabenz (Wytensin®) is an alpha-2 adrenergic receptor agonist marketed for use in humans as an anti-hypertensive agent. Recent reports indicate that guanabenz has been administered to horses in small doses (0.04 mg/kg) for its anti-hypertensive effects. While this offers both benefits of sedation of the horse as well as amelioration of pulmonary hypertension during running exercise and consequent Exercise-Induced Pulmonary Hemorrhage (EIPH), guanabenz is currently proscribed in most racing jurisdictions and its …

A 20-year-old, male, neutered camel presented with an 8-month history of a proliferative and ulcerated cush pad lesion refractory to topical wound management. The referring veterinarian performed a punch biopsy to further investigate the tissue; findings were consistent with granulation tissue. The patient was referred to University of Tennessee Farm Animal Medicine and Surgery service for additional diagnostics, surgical debridement and intensive wound care. The camel underwent surgical debridement of the lesion, and histopathology was consistent with a squamous cell carcinoma. Bloodwork revealed a severe non-regenerative anaemia and leukocytosis suspected to be paraneoplastic changes. During hospitalisation, it was identified that …

Pandemics And Animal Welfare: A Mixed-Methods Inquiry Into How The Covid-19 Pandemic Has Affected The Companion Animal Industry In Northwest Arkansas, Sabrina G. Cox, Isabel Whitehead
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The first cases of coronavirus reported in the United States came in January 2020 (World Health Organization, 2020). In the two years since then, countries around the world have been affected by COVID-19 and the subsequent social, economic, and mental health issues. Previous research shows that the animal healthcare field is already overrun with burnout, substance abuse, depression, and increased levels of stress (Gardner and Hini, 2006), and the pandemic has only compounded these issues (Mair et al., 2020). Observing a lack of meaningful reporting on the issues affecting veterinary staff led the researchers to investigate staff members’ practices, day- …

Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian M. Gilbert, Jossie M. Santamaria, Gisela F. Erf
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Lipoteichoic acid (LTA) is a cell-wall polymer in Gram-positive bacteria that stimulates inflammation. Few studies have investigated in vivo immune response to LTA, and none of the in vivo studies have been performed in birds. For this project, the pulp (a skin derivative) of growing feathers (GF) of chickens was used to investigate the in vivo effects of intradermally injected LTA. In Study 1, GF of chickens were injected with 10 μL of differing concentrations of LTA (0.1, 1.0, 10, 100 or 250 μg LTA/mL; 3 chickens/dose). Growing feathers were plucked before injection (0 h) and at 6, 24, 48, …

Identifying Bisphosphonate Protein Biomarkers In Equine Sera Using Mass Spectrometry Methods, Malinda Jayne Alison Porter
Theses and Dissertations--Veterinary Science
Bone resorptive diseases affect humans and horses, alike. Examples of these diseases include osteoporosis, Paget’s disease, and osteogenesis imperfecta in humans, and navicular disease in the horse (Mitchell et al., 2019; Suva et al., 2021). Bisphosphonates are used to treat these diseases, and may remain in the bone for several years after administration, demonstrating the need for newer drug testing methods.
The purpose of the discovery phase of this study was to use blood samples of in-training horses which had been given an initial administration of the bisphosphonate tiludronate and identify protein biomarkers that changed in response to this class …
Defining And Assessing Sentience, Barry O. Hughes
Defining And Assessing Sentience, Barry O. Hughes
Animal Sentience
Precisely what is meant by the term sentience and how does it overlap with being conscious? We accept that animals have feelings but how do we know what they are and can we measure them? It is important that we clarify the terminology underlying these difficult concepts. Over the last 50 years a scientific discipline has developed to tackle these questions in a systematic way. We have to avoid thoughtless anthropomorphism yet we have to try to relate sentience in animals, as appropriate, to corresponding experiences in humans.

The Effects Of Cannabidiol On Senior Equine Health, Shelley Turner
The Effects Of Cannabidiol On Senior Equine Health, Shelley Turner
Theses and Dissertations--Veterinary Science
Cannabis sativa L., has been revealed to produce hundreds of phytocannabinoids, of which cannabidiol (CBD) is one of the most desired. It has been revealed that CBD can potentially treat inflammation and act as an analgesic in humans without psychoactive effects of delta-9-tetrahydrocannabinol (THC). Recently, there has been interest in understanding the potential health benefits of CBD for horses. With an increasing senior horse population (< 15 years old), alternatives to the use of non-steroidal anti-inflammatory drugs (NSAIDs) such as phenylbutazone, firocoxib, and flunixin meglumine, are desired as these common anti-inflammatory treatments have negative side effects. Because senior horses may have chronic low-grade inflammation, termed inflamm-aging, they are a natural model to investigate the efficacy of CBD on inflammatory responses as well as other health parameters. Given this interest, and due to the lack of research conducted on CBD in the horse, the overall objective of this dissertation work was to conduct both basic and applied research investigating the effects of CBD on equine immune function and health. The first objective was to determine the in vitro effects of CBD as an anti-inflammatory. Peripheral blood mononuclear cells (PBMCs) from senior horses were cultured in vitro with increasing concentrations of pure CBD dissolved in dimethyl sulfoxide (DMSO). These cells were …

The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips
Animal Sentience
In their target article, Rowan et al (2022) make a welcome attempt to chart the development of Western progress over the past two hundred years toward formally recognizing that animals feel. They outline the heroic efforts of Compassion in World Farming to gain for animals the status of sentient beings rather than merely human property. A broader view exists, from human prehistory to the present day, in which animals have been (and still are) understood to be sentient by indigenous peoples as well as by some Eastern religions. Growing recognition in the West that animals feel represents a new age …

School of Veterinary and Biomedical Sciences: Faculty Publications
Ivermectin is widely used in both animals and humans as an FDA-approved parasiticide. Ivermectin has also been reported to have antiviral activity against several viruses including coronaviruses. There are reports that indicate ivermectin may have some role in diminishing the disease caused by SARS-CoV-2, but the evidence is inconclusive. The objective of this study was to determine if ivermectin was efficacious in inhibiting avian infectious bronchitis virus (IBV, a coronavirus) replication in chicken embryos. Briefly, our approach was to use the Massachusetts vaccine strain of IBV in combination with various doses of ivermectin and then inoculate these preparations into chicken …

Nanoparticles (NPs) made of metals, polymers, micelles, and liposomes are increasingly being used in various biomedical applications. However, most of these NPs are hazardous for long- and short-term use and hence have restricted biomedical applications. Therefore, naturally derived, biocompatible, and biodegradable nanoconstructs are being explored for such applications. Inspired by the biology of viruses, researchers are exploring the viral proteins that hold considerable promise in biomedical applications. The viral proteins are highly stable and further amenable to suit specific biological applications. Among various viral proteins, vesicular stomatitis virus glycoprotein (VSV-G) has emerged as one of the most versatile platforms for …

In the last 15 years, crustacean fisheries have experienced billions of dollars in economic losses, primarily due to viral diseases caused by such pathogens as white spot syndrome virus (WSSV) in the Pacific white shrimp Litopenaeus vannamei and Asian tiger shrimp Penaeus monodon. To date, no effective measures are available to prevent or control disease outbreaks in these animals, despite their economic importance. Recently, double-stranded RNA-based vaccines have been shown to provide specific and robust protection against WSSV infection in cultured shrimp. However, the limited stability of double-stranded RNA is the most significant hurdle for the field application of these …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Pancreatic beta-cell replacement is recognized for feasible type 1 diabetes (T1D) treatment. However, in post-transplantation, the autoimmune destruction incidentally attacks the activity and survival of beta-cells are reported in animal and human. To address these concerns, the generation of immortalized, biocompatible beta-cells, and the engraftment platform are insightfully investigated. The stepwise chemical process was used for in vitro Insulin-producing cells (IPCs) production from mouse gingival fibroblast-induced pluripotent stem cells (mGF-iPSCs). The real-time qRT-PCR, glucose stimulation C-peptide/Insulin secretion, immunostaining, and visible cell methods were examined during IPC differentiation. The encapsulated-IPC beads were loaded into subcutaneous pocket space via transplantation platform. Completed …

In Vitro Inhibitory Effects Of Turmeric Extracts Against Biofilm Formation And Virulence Of Flavobacterium Oreochromis, Sirawich Ngernson
Chulalongkorn University Theses and Dissertations (Chula ETD)
Flavobacterium oreochromis is an opportunistic bacteria and causative agent of columnaris disease that affects freshwater fish worldwide. To initiate infection, the bacteria are required to attach and form biofilm on the fish's skin. The bacteria cells in the biofilm then produce toxins that can degrade fish connective tissue, resulting in lesions and ulcers. This study aimed to evaluate the efficacy of turmeric (Curcuma longa L.) extract by three organic solvents (hexane, ethanol, and methanol) in biofilm inhibition and modulation of biofilm-associated genes of F. oreochromis. Turmeric extracts by three different organic solvents were tested for their ability to inhibit the …

Seroprevalence Of Lawsonia Intracellularis Antibody Among Swine Herds In Thailand, December 2021-March 2022, Thanh Nguyen Che
Chulalongkorn University Theses and Dissertations (Chula ETD)
The gastrointestinal infectious diseases caused by bacteria have been a major problem in the Thai swine industry. Porcine proliferative enteropathy (PPE), also known as porcine ileitis, is an enteric infectious disease caused by Lawsonia intracellularis. Porcine ileitis has been an economic threat to the global pork production system due to various types of diarrheas. Serological diagnosis can be applied for determining pathogen-antibodies seroprevalence and the timing of L. intracellularis infection when introduced to the herd. A lack of serological data since 2009, as well as recent antibiotic usage restrictions, may have a negative impact on porcine ileitis seroprevalence in Thailand. …

Characterization And Manipulation Of O-Glcnacylation In Granulosa Cells Of Bovine Ovarian Antral Follicles, Abigail Marie Maucieri
Graduate College Dissertations and Theses
Glucose is widely recognized as the preferred energy substrate for metabolism by granulosa cells (GCs). Yet in most cells, 2-5% of glucose is shunted through the hexosamine biosynthesis pathway (HBP) for O-linked N-acetylglucosaminylation (O-GlcNAcylation). O-GlcNAcylation is an evolutionarily-conserved, post-translational process that modifies serine and threonine residues on a variety of proteins. O-GlcNAcylation is also considered a nutrient sensor that can regulate cellular processes such as metabolism, signal transduction, and proliferation. In this respect, O-GlcNAcylation may be similar to, and possibly mediate, AMP-activated protein kinase (AMPK) signaling and its nutrient-sensing actions. However, the occurrence of O-GlcNAcylation and its relative importance to …

The Acute Physiological Response Of Polar Bears To Helicopter Capture, John P. Whiteman, Henry J. Harlow, George M. Durner, Eric V. Regehr, Steven C. Amstrup, Anthony M. Pagano, Merav Ben-David
Biological Sciences Faculty Publications
Many wildlife species are live captured, sampled, and released; for polar bears (Ursus maritimus) capture often requires chemical immobilization via helicopter darting. Polar bears reduce their activity for approximately 4 days after capture, likely reflecting stress recovery. To better understand this stress, we quantified polar bear activity (via collar‐mounted accelerometers) and body temperature (via loggers in the body core [Tabd] and periphery [Tper]) during 2–6 months of natural behavior, and during helicopter recapture and immobilization. Recapture induced bouts of peak activity higher than those that occurred during natural behavior for 2 of 5 bears, …

No Difference In Corticosterone Concentrations Between Missouri Three-Toed Box Turtles Living In An Urban And A Rural Site, Bennett A. Lamczyk, Jamie L. Palmer, Corinne P. Kozlowski, Stephen Blake, Sharon L. Deem
Human–Wildlife Interactions
Baseline health data for species of conservation concern are important for understanding threats to the long-term viability of populations. One indication of health is physiological stress among individuals. Corticosterone (CORT) is frequently used to quantify stress in free-living reptile populations, as high values may be associated with reduced fitness. Herein, we describe and validate methods for quantifying blood CORT levels in three-toed box turtles (Terrapene mexicana triunguis). We subsequently use this information to evaluate stress levels in 2 populations of free-living three-toed box turtles in Missouri, USA. To our knowledge, this is the first quantification of CORT levels …

Rowan et al. (2022) provide a useful summary of the history and development of the philosophical, public, and legal recognition of animal sentience and its importance in improving the welfare of animals. Here I argue for the incorporation of the precautionary principle in sentience recognition, and the wider significance of sentience recognition to the current climate, biodiversity and human health crises.

The small Indian mongoose (Urva auropunctata) is a non-native invasive species across the Caribbean and a rabies reservoir on at least four islands in the region. Although previous studies reported mongoose density estimates in their non-native range, the variability in trapping designs, study seasonality, and analytical methods among studies precludes direct comparisons. This study is the first to report mongoose densities for the island of St. Kitts, West Indies. Our objective was to quantify mongoose densities across four habitats characteristic for the island. High capture and recapture rates in this study resulted in detailed estimates of spatial heterogeneity …
