Maxwell H. Gluck Equine Research Center Faculty Publications

Background: Equine gastrointestinal nematodes (GINs) have been the subject of intermittent studies in Australia over the past few decades. However, comprehensive information on the epidemiology of equine GINs, the efficacy of available anthelmintic drugs and the prevalence of anthelmintic resistance (AR) in Australasia is lacking. Herein, we have systematically reviewed existing knowledge on the horse GINs recorded in Australia, and main aspects of their pathogeneses, epidemiology, diagnoses, treatment and control.

Methods: Six electronic databases were searched for publications on GINs of Australian horses that met our inclusion criteria for the systematic review. Subsets of publications were subjected to review epidemiology, …

Determining Mediators Of Naive T Cell Motility And Dc Association In The Lymph Node, Janie Rae Byrum

Biomedical Sciences ETDs

To become activated and perform effector functions, naive T cells move within lymph nodes to scan dendritic cells presenting antigen. Previous work has shown naive T cell activation is promoted by interleukin 7 in vivo, and it does so by regulating the T cell:dendritic cell interaction. Our work identifies a novel role for IL-7 in mediating naive T cell motility in the lymph node and promoting T cell association with DCs. Additionally, we have developed a method for analyzing microscopy images, regionalized normalized mutual information, to assess intercellular associations between T cells and other cells within the lymph node. Dendritic …

The Validity Of Medicare Claims-Based Codes To Identify Nontuberculous Mycobacterial Infection In Patients With Bronchiectasis, Jennifer Ku

OHSU-PSU School of Public Health Annual Conference

Background: Nontuberculous mycobacteria (NTM) is a disease of increasing incidence, causing permanent airway damage leading to destructive pulmonary disease. Medicare claims-based codes have been used to identify NTM infection and to evaluate trends in diagnosis and disease outcomes. However, claims-based codes to identify NTM infection have not been validated.

Methods: We linked patients with a bronchiectasis diagnosis (ICD-9-CM 494.0 or 494.1) excluding cystic fibrosis from the national 2006-2014 Centers for Medicare and Medicaid (Medicare) data to the U.S. Bronchiectasis Research Registry (BRR). The BRR is a national prospective cohort of patients with bronchiectasis, that collects detailed clinical, laboratory, microbiology and …

One Health is a collaborative, interdisciplinary effort that seeks optimal health for people, animals, plants, and the environment. Toxoplasmosis, caused by Toxoplasma gondii, is an intracellular protozoan infection distributed worldwide, with a heteroxenous life cycle that practically affects all homeotherms and in which felines act as definitive reservoirs. Herein, we review the natural history of T. gondii, its transmission and impacts in humans, domestic animals, wildlife both terrestrial and aquatic, and ecosystems. The epidemiology, prevention, and control strategies are reviewed, with the objective of facilitating awareness of this disease and promoting transdisciplinary collaborations, integrative research, and capacity building among universities, …

Transposon Mutagenesis In Mycobacterium Avium Subspecies Paratuberculosis, John P. Bannantine, Denise K. Zinniel, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

While transposon mutagenesis has been developed for Mycobacterium avium subspecies paratuberculosis (Map), relatively few laboratories have adopted this important genetic tool to examine gene function and essentiality. Here we describe the construction of a Map transposon library using the Himar1 mariner transposon, but concepts can also be applied to the Tn5367 transposon, which has also been used by our group. Delivery of the transposon is by a temperature-sensitive phagemid, ϕMycoMarT7, and plating transductants requires patience and specialized media due to length of incubation required to observe colonies. Several transposon mutants obtained from these libraries have been tested in vaccine and …

Z4, A Slow Puncture: An Autoethnographic Exploration Of Language, Embodiment, And Meaning-Making, Charlotte Rose Samuels

Independent Study Project (ISP) Collection

In my ISP, I explored language as it relates to the ways in which people living in Cato Manor make sense of HIV/AIDS in their community. With 7.1-7.2 million people living with HIV (PLWHIV) in South Africa, individuals across the country are either infected or affected by illness. KwaZulu-Natal (KZN), the province with the highest rate of HIV, is also the province that was surveyed with the disproportionately highest internal stigma rates for PLWHIV. High prevalence of HIV, particularly in KZN, calls for a constant contextualization of life in the presence of illness.

Throughout the world, metaphor and symbolism is …

From The American People: An Autoethnographic Exploration Of South African Ngos' Perceptions Of Pepfar, Antonia Asher

Independent Study Project (ISP) Collection

The aim of this research was to understand what the ideal partnership would be between United States (US) governmental aid agencies and South African non-governmental organizations (NGOs), specifically concerning HIV/AIDS programs funded by the US President’s Emergency Plan for AIDS Relief (PEPFAR), from the perspective of NGOs. PEPFAR is the largest relief fund for a single disease; thus, I additionally sought to deeply reflect upon myself as a US citizen in South Africa, a country that has received trillions of dollars from taxpayers such as myself.

To accomplish this, I interviewed NGO staff about the nature of current partnerships, outcomes …

Vaccine Hesitancy In The United States And Switzerland, Anna E. Lunderberg

Independent Study Project (ISP) Collection

Vaccine hesitancy (VH), or the reluctance or refusal to participate in vaccination programs, is a complex phenomenon with far-reaching impacts on society. VH can impact vaccine uptake and facilitate subsequent outbreaks, as seen with the case of measles. Perceptions of vaccination are similar in the United States and Switzerland, and misinformation in each country contributed to VH through impaired parental risk-benefit analysis; parental analysis and subsequent VH is associated with both anti-vaccination messages gaining prominence and a decrease in the public perception of the health risk from vaccine-preventable diseases (VPDs). There are many proposed strategies for addressing VH on both …

Environmental Transmission Of Toxoplasma Gondii: Oocysts In Water, Soil And Food, Karen Shapiro, Lillian Bahia-Oliveira, Brent Dixon, Aurélien Dumètre, Luz A. De Wit, Elizabeth Vanwormer, Isabelle Villena

School of Veterinary and Biomedical Sciences: Faculty Publications

Toxoplasma gondii is a zoonotic protozoan parasite that can cause morbidity and mortality in humans, domestic animals, and terrestrial and aquatic wildlife. The environmentally robust oocyst stage of T. gondii is fundamentally critical to the parasite's success, both in terms of its worldwide distribution as well as the extensive range of infected intermediate hosts. Despite the limited definitive host species (domestic and wild felids), infections have been reported on every continent, and in terrestrial as well as aquatic environments. The remarkable resistance of the oocyst wall enables dissemination of T. gondii through watersheds and ecosystems, and long-term persistence in diverse …

Translating Antimicrobial Resistance: A Case Study Of Context And Consequences Of Antibiotic-Related Communication In Three Northern Thai Villages, Nutcha Charoenboon, Marco J. Haenssgen, Penporn Warapikuptanun, Thipphaphone Xayavong, Yuzana Khine Zaw

Goal 16: Peace, Justice and Strong Institutions

Antimicrobial resistance (AMR) threatens to cause ten million deaths annually by 2050, making it a top item on the global health agenda. The current global policy response is multi-faceted, wherein behavioural dimensions like people’s medicine use are being predominantly addressed with education and communication campaigns. The social sciences literature suggests that cross-contextual translation of medical knowledge in global awareness campaigns can create misunderstandings and adverse behavioural responses. However, the consequences of AMR communication in low-income and middle-income contexts remain largely undocumented. In response to the empirical knowledge gap, this study presents the case study of educational activity in three northern …

Characterization Of Immunomodulatory Microbial Factors In Medicinal Plants, Kriti Kalpana

Dissertations, Theses, and Capstone Projects

Medicinal plants are one of the biggest sources of natural products with therapeutic importance. There are currently over 28,000 plants with putative medicinal values. Plant-derived compounds have been explored extensively for various biological activities ranging from anti-cancer, immune-boosting to anti-inflammatory and anti-oxidant. Some of the most important therapeutic agents are of plant-origin, such as paclitaxel from Pacific yew (Taxus brevifolia) and artemisinin from qinghao su (a Chinese medicinal herb; a.k.a. Artemisia annua) to name a few.

The study presented in this thesis started out as classical pharmacognosy research, which focused on the identification of immunostimulatory factors in …

Non-Invasive Analysis Of The Sputum Transcriptome Discriminates Clinical Phenotypes Of Asthma, Xiting Yan

Yale Day of Data

Whole transcriptome wide gene expression profiles in the sputum and circulation from 100 asthma patients were measured using the Affymetrix HuGene 1.0ST arrays. Unsupervised clustering analysis based on pathways from KEGG were used to identify TEA clusters of patients from the sputum gene expression profiles. The identified TEA clusters have significantly different pre-bronchodilator FEV1, bronchodilator responsiveness, exhaled nitric oxide levels, history of hospitalization for asthma and history of intubation. Evaluation of TEA clusters in children from Asthma BRIDGE cohort confirmed the identified differences in intubation and hospitalization. Furthermore, evaluation of the TH2 gene signatures suggested a much lower prevalence of …

Plasmodium Para-Aminobenzoate Synthesis And Salvage Resolve Avoidance Of Folate Competition And Adaptation To Host Diet, Joachim Michael Matz, Mutsumi Watanabe, Mofolusho Falade, Takayuki Tohge, Rainer Hoefgen, Kai Matuschewski

Pharmaceutical Sciences Faculty Publications

Folate metabolism is essential for DNA synthesis and a validated drug target in fast-growing cell populations, including tumors and malaria parasites. Genome data suggest that Plasmodium has retained its capacity to generate folates de novo. However, the metabolic plasticity of folate uptake and biosynthesis by the malaria parasite remains unresolved. Here, we demonstrate that Plasmodium uses an aminodeoxychorismate synthase and an aminodeoxychorismate lyase to promote the biogenesis of the central folate precursor para-aminobenzoate (pABA) in the cytoplasm. We show that the parasite depends on de novo folate synthesis only when dietary intake of pABA by …

Structural And Functional Determinants Of Rodent And Human Surfactant Protein A: A Synthesis Of Binding And Computational Data, Armen Nalian, Todd M. Umstead, Ching-Hui Yang, Patricia Silveyra, Neal J. Thomas, Joanna Floros, Francis X. Mccormack, Zissis C. Chroneos

Faculty Publications

Surfactant protein A (SP-A) provides surfactant stability, first line host defense, and lung homeostasis by binding surfactant phospholipids, pathogens, alveolar macrophages (AMs), and epithelial cells. Non-primates express one SP-A protein whereas humans express two: SP-A1 and SP-A2 with core intra- and inter-species differences in the collagen-like domain. Here, we used macrophages and solid phase binding assays to discern structural correlates of rat (r) and human (h) SP-A function. Binding assays using recombinant rSP-A expressed in insect cells showed that lack of proline hydroxylation, truncations of amino-terminal oligomerization domains, and site-directed serine (S) or alanine (A) mutagenesis of cysteine 6 (C6S), …

Antibodies In The Diagnosis, Prognosis, And Prediction Of Psychotic Disorders., Thomas A Pollak, Jonathan P Rogers, Robert G Nagele, Mark Peakman, James M Stone, Anthony S David, Philip Mcguire

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Blood-based biomarker discovery for psychotic disorders has yet to impact upon routine clinical practice. In physical disorders antibodies have established roles as diagnostic, prognostic and predictive (theranostic) biomarkers, particularly in disorders thought to have a substantial autoimmune or infective aetiology. Two approaches to antibody biomarker identification are distinguished: a "top-down" approach, in which antibodies to specific antigens are sought based on the known function of the antigen and its putative role in the disorder, and emerging "bottom-up" or "omics" approaches that are agnostic as to the significance of any one antigen, using high-throughput arrays to identify distinctive components of the …

Reverse Genetics Systems As Tools To Overcome The Genetic Diversity Of Lassa Virus, Brett Beitzel, Christine E. Hulseberg, Gustavo Palacios

United States Army: Publications

Lassa virus is endemic in a large area of sub-Saharan Africa, and exhibits a large amount of genetic diversity. Of the four currently recognized lineages, lineages I–III circulate in Nigeria, and lineage IV circulates in Sierra Leone, Guinea, and Liberia. However, several newly detected lineages have been proposed. LASV genetic diversity may result in differences in pathogenicity or response to medical countermeasures, necessitating the testing of multiple lineages during the development of countermeasures and diagnostics. Logistical and biosafety concerns can make it difficult to obtain representative collections of divergent LASV clades for comparison studies. For example, lack of a cold …

Role Of T-Bet In Production Of Immunoglobulin Isotypes In An Influenza Setting, David Sidhom

Honors Undergraduate Theses

Influenza is one of the most common diseases worldwide, yet the vaccines against influenza are only 35% effective at protecting against infection. Creating a more effective vaccine requires an understanding of the foundation and the factors that contribute to a strong and protective adaptive immune response. T-bet [TBX21] is a transcription factor that plays an instrumental role in the orchestration of the type 1 immune response, which is the specialized response used by the immune system for a cell-mediated response against intracellular pathogens, such as influenza. It has yet to be explored in an influenza setting on the role T-bet …

Performance Differences Between Two Groups Of Commercial Pigs Following Experimental Infection With Prrs Virus 1-7-4, Erin Little

Electronic Theses and Dissertations

Porcine reproductive and respiratory syndrome virus (PRRSV) is the costliest swine disease in North America. Vaccines and management alone have not been effective in controlling this disease. Genetic selection for resilience may be a complimentary approach for controlling PRRSV. The objective of this study was to estimate performance differences between two groups of pigs from the same commercial line following infection with PRRSV 1-7-4: 1) pigs sired by boars selected based on a standard index (TN-S), which emphasized feed efficiency and carcass quality; and 2) pigs sired by boars selected based on an experimental index (TN-E), which emphasized feed intake, …

How Do Teachers Use Comics To Promote Engagement, Equity, And Diversity In Science Classrooms?, Camilla Matuk, Talia Hurwich, Amy Spiegel, Judy Diamond

World of Viruses

Equitable learning opportunities are critical to the goals of science education. However, major curriculum standards are vague on how to achieve equity goals, and educators must often develop their own resources and strategies to achieve equity goals. This study examines how educators used a comic book series designed to interest youth in virology as a way to make science more broadly appealing to their diverse students. We begin with the notion of Pedagogical Design Capacity, which describes a dynamic relationship between teachers and their tools and the ability for teachers to perceive and leverage affordances of artifacts as tools in …

Novel Amphiphilic Cyclobutene And Cyclobutane Cis-C18 Fatty Acid Derivatives Inhibit Mycobacterium Avium Subsp. Paratuberculosis Growth, Denise K. Zinniel, Wantanee Sittiwong, Darrell D. Marshall, Govardhan Rathnaiah, Isin T. Sakallioglu, Robert Powers, Patrick H. Dussault, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

Mycobacterium avium subspecies paratuberculosis (Map) is the etiologic agent of Johne’s disease in ruminants and has been associated with Crohn’s disease in humans. An effective control of Map by either vaccines or chemoprophylaxis is a paramount need for veterinary and possibly human medicine. Given the importance of fatty acids in the biosynthesis of mycolic acids and the mycobacterial cell wall, we tested novel amphiphilic C₁₀ and C₁₈ cyclobutene and cyclobutane fatty acid derivatives for Map inhibition. Microdilution minimal inhibitory concentrations (MIC) with 5 or 7 week endpoints were measured in Middlebrook 7H9 base broth media. We compared the …

Investigation Of Congestive Heart Failure In Beef Cattle In A Feedyard At A Moderate Altitude In Western Nebraska, Rodney A. Moxley, David R. Smith, Dale M. Grotelueschen, Tom Edwards, David Steffen

School of Veterinary and Biomedical Sciences: Faculty Publications

Right-sided congestive heart failure (brisket disease) commonly occurs in cattle raised at elevations >2,500– 3,500 m. We investigated clinical cases resembling brisket disease at a western Nebraska feedyard at a moderate altitude (1,369 m). Over a 15-mo period (2009–2010), we examined 17 cases (16 steers and 1 heifer), all purebred Angus. All animals had clinical right-sided heart failure: brisket and ventral abdominal edema, and severe chronic passive congestion of the liver. Gross examination confirmed right ventricular hypertrophy (left ventricle plus septum: right ventricle weight ratio mean: 1.33 vs. 2.8–4.0 reference interval). Microscopically, all 17 cases had interstitial fibrosis (mean score: …

Diagnosis Of Schistosoma Mansoni Infections: What Are The Choices In Brazilian Low-Endemic Areas?, Vanessa Silva-Moraes, Lisa M. Shollenberger, Liliane Maria Vidal Siqueira, William Castro-Borges, Donald A. Harn, Rafaella Fortini Queiroz E. Grenfell, Ana Lucia Teles Rabello, Paulo Marcos Zech Coelho

Biological Sciences Faculty Publications

The population of Brazil is currently characterised by many individuals harbouring low-intensity Schistosoma mansoni infections. The Kato-Katz technique is the diagnostic method recommended by the World Health Organization (WHO) to assess these infections, but this method is not sensitive enough in the context of low egg excretion. In this regard, potential alternatives are being employed to overcome the limits of the Kato-Katz technique. In the present review, we evaluated the performance of parasitological and immunological approaches adopted in Brazilian areas. Currently, the diagnostic choices involve a combination of strategies, including the utilisation of antibody methods to screen individuals and then …

Pyocyanin, A Virulence Factor Produced By Sepsis-Causing Pseudomonas Aeruginosa, Promotes Adipose Wasting And Cachexia, Nika Larian

Theses and Dissertations--Pharmacology and Nutritional Sciences

Sepsis is a leading cause of death among critically ill patients that results in metabolic alterations including hypercatabolism, lipoatrophy, and muscle wasting, contributing to the development of cachexia. Septic cachexia is associated with loss of body weight, fat mass, and lean mass and dysregulated immune function. There are currently no efficacious treatment strategies for septic cachexia, and nutritional interventions have limited success in preventing hypercatabolic wasting. Pyocyanin is a virulence factor produced by sepsis-causing Pseudomonas aeruginosa that has been shown to activate the aryl hydrocarbon receptor (AhR), increase inflammation, and produce reactive oxygen species. Thus, pyocyanin represents a novel mechanistic …

Control Efforts And Serologic Survey Of Pseudorabies And Brucellosis In Wild Pigs Of Tennessee, Lisa I. Muller, Neelam C. Poudyal, Roger Applegate, Chuck Yoest

Human–Wildlife Interactions

European wild pigs (Sus scrofa) are an introduced invasive species that now constitute a major threat to agriculture and the natural ecology of the environments they now inhabit. Wild pigs also carry many diseases known to infect wildlife, humans, and livestock. Two of these diseases, pseudorabies (PRV) and brucellosis, constitute major diseases in the United States. Better data are needed regarding the prevalence of these diseases in wild pigs to understand and manage the potential risks to wildlife, humans, and livestock. From July 1, 2011 to June 30, 2017, Tennessee Wildlife Resources Agency personnel trapped and euthanized 4,727 …

Evaluations Of Health In Sympatric Free-Ranging Saguinus Imperator And Leontocebus Weddelli Using Neopterin, Urinalysis, And Blood Chemistry Analyses, Alexandra J. Sacco

All Master's Theses

This thesis is composed of one journal-ready article and one chapter that includes a preliminary interpretation of data for later publication. In summary, this thesis proposes the use of three different methods of evaluating the health status of New World Monkeys: urinary neopterin measurement, blood chemistry analyses, and urinalysis. Chapter II addresses the question of whether or not the neopterin molecule, a biomarker for cell-mediated immune system activation, is conserved across primate taxa. To do so, we collected urine samples across three New World Monkey (NWM) families including captive Leontopithecus rosalia and Pithecia pithecia, and wild populations of Leontocebus …

School of Veterinary and Biomedical Sciences: Faculty Publications

Enteroviral infections are frequent, often asymptomatic in humans and during gravidity. The present study is an extension of our previous investigations where we had shown pancreatitis in challenged pups of CVB4-E2-infected dams. Present investigation describes the effect of gestational infection with this virus on the pancreas of both dams and their challenged pups. Gravid CD1 outbred mice were orally infected with CVB4-E2 virus at different gestation times. Pups were challenged orally with the same virus after 25 days of birth. Organs were collected at selected intervals postinfection (p.i.), and replicating virus and viral-RNA copies were analyzed. Additional readouts included histopathology …

The Role Of Isothiocyanates As Cancer Chemo‐Preventive, Chemo‐Therapeutic And Anti‐Melanoma Agents, Melina Mitsiogianni, Georgios Koutsidis, Nikos Mavroudis, Dimitrios T. Trafalis, Sotiris Botaitis, Rodrigo Franco, Vasilis Zoumpourlis, Tom Amery, Alex Galanis, Aglaia Pappa, Mihalis I. Panayiotidis

School of Veterinary and Biomedical Sciences: Faculty Publications

Many studies have shown evidence in support of the beneficial effects of phytochemicals in preventing chronic diseases, including cancer. Among such phytochemicals, sulphur‐containing compounds (e.g., isothiocyanates (ITCs)) have raised scientific interest by exerting unique chemopreventive properties against cancer pathogenesis. ITCs are the major biologically active compounds capable of mediating the anticancer effect of cruciferous vegetables. Recently, many studies have shown that a higher intake of cruciferous vegetables is associated with reduced risk of developing various forms of cancers primarily due to a plurality of effects, including (i) metabolic activation and detoxification, (ii) inflammation, (iii) angiogenesis, (iv) metastasis and (v) regulation …

Biological Sciences Faculty Publications

Background

Despite decades of use of control programs, schistosomiasis remains a global public health problem. To further reduce prevalence and intensity of infection, or to achieve the goal of elimination in low-endemic areas, there needs to be better diagnostic tools to detect low-intensity infections in low-endemic areas in Brazil. The rationale for development of new diagnostic tools is that the current standard test Kato-Katz (KK) is not sensitive enough to detect low-intensity infections in low-endemic areas. In order to develop new diagnostic tools, we employed a proteomics approach to identify biomarkers associated with schistosome-specific immune responses in hopes of developing …

Preconditioning Of The Tumor Microenvironment By Means Of Low Dose Chemotherapies For An Effective Immunotherapy Of Breast Cancer, Hussein F. Aqbi

Theses and Dissertations

Breast cancer mortality is mainly due to distant recurrence of the disease arising from dormant tumor cells established by cancer therapies. Patients who initially respond to cancer therapies often succumb to distant recurrence of the disease. It is not clear why people with the same type of breast cancer respond to treatments differently; some escape from dormancy and relapse earlier than others. In addition, some tumor clones respond to immunotherapy while others do not. We investigated how autophagy plays a role in accelerating or delaying recurrence of neu overexpressing mouse mammary carcinoma (MMC) following adriamycin (ADR) treatment, and in affecting …

Investigating The Role Of Coyotes, Canis Latrans, In The Spread Of Parasites And Arthropod-Borne Diseases In Georgia, Usa., Ansleigh Banks

College of Graduate Studies: Theses & Dissertations

In order to analyze the role of coyotes, Canis latrans, as hosts of parasites and arthropod-borne diseases in the state of Georgia, USA, 38 coyotes representing 18 counties and multiple geographic regions of the state were dissected and analyzed for the presence of Dirofilaria immitis, intestinal parasites, ectoparasites, and tick-borne illnesses. Mosquitoes from the locations which the coyotes originated were trapped and analyzed for the presence of D. immitis larvae. In compliance with IACUC guidelines, coyotes were obtained from individuals who had previously hunted or trapped the coyotes for leisure. Parasites were identified based on morphological features with the use …
