Phylogenetic Investigation Of Enteric Bovine Coronavirus In Ireland Reveals Partitioning Between European And Global Strains, Lynda Gunn, P. J. Collins, M. J. O'Connell, Helen O'Shea

Department of Biological Sciences Publications

Background

Bovine coronavirus is a primary cause of neonatal calf diarrhea worldwide, and is also associated with acute diarrhea in adult cattle during the winter season. There are no reports on molecular characterization of bovine coronavirus in Ireland, and little data exists apart from serological studies.

Findings

In this study, 11 neonatal (mean age 9 days) calf BCoV strains from the south of Ireland were collected over a one year period and characterized using molecular methods. The spike gene which encodes a protein involved in viral entry, infectivity and immune response shows the most variability amongst the isolates and was …

Evidence For Using Immunosuppressive Treatments When Treating Idiopathic Non-Infectious Uveitis: A Systematic Review And Meta-Analysis, Hargurinder Singh

Electronic Thesis and Dissertation Repository

Idiopathic non-infectious uveitis is the spontaneous inflammation of the eye, which can lead to blindness if not treated correctly. Due to long-term side effects of corticosteroids, 4 classes of off-label immunosuppressive treatments are sometimes used (alkylating agents, inhibitors of T-lymphocyte signalling, antimetabolites and biological modifiers). We conducted a systematic review and meta-analysis to assess the effectiveness of different treatment classes on uveitis patients with similar characteristics. Results of the systematic review concurred with the conclusions from the meta-analysis, which found that all immunosuppressive treatments improved patient vision, with a statistically significant change in logMAR of -0.11 (95% CI of -0.152 …

Design And Testing Of Novel Anthrax Vaccines Utilizing A Tobacco Mosaic Virus Expression System, Ryan C. Mccomb

KGI Theses and Dissertations

Anthrax is a potentially fatal disease caused by the bacteria Bacillus anthracis. Infection and disease occur after spores gain entry into the body, germinate into vegetative bacteria, and produce toxin. Bacillus anthracis spores have been engineered as bioweapons and have been used repeatedly in warfare and terrorism to inflict casualties in military and civilian populations. Currently, only one vaccine has been approved for prevention of anthrax in the United States. This vaccine is an undefined product that is difficult to produce, requires a long vaccination schedule, and is reactogenic. Efforts to make an improved anthrax vaccine are being pursued. …

Open Educational Resources: A Catalyst For Innovation, Dominic Orr, Michele Rimini, Dirk Van Damme

Concepts in Animal Parasitology Textbook

Foreword:

Open educational resources (OER) are rapidly becoming a major phenomenon in education across OECD countries and beyond. Initiated largely at the level of institutions by pioneers and technology advocates, the OER community has grown considerably over the past ten years and the impact of OER on educational systems has become an issue of public policy. The open education community is increasingly well organised and enjoys support from various institutions and foundations. National governments have developed, or are in the process of developing, open policies to support access to and use of OER.

It is the task of the OECD …

Health Assessment Of Two Reintroduced Populations Of American Martens (Martes Americana) In Michigan, Maria Catherine Spriggs

Doctoral Dissertations

The American marten (Martes americana) was extirpated from Michigan during the early-20th century due to loss of vast areas of mature conifer forest and unregulated trapping. The species was reintroduced into the Upper Peninsula (UP) and Northern Lower Peninsula (NLP) during the mid-20th century. While the American marten population in the UP has grown and is doing well, the population in the NLP has been less successful. The reasons for the limited success of the NLP population are unknown, but may include lack of suitable habitat, limited reproductive success, poor genetic diversity, disease, or negative environmental impacts. American …

Viability Of Developmental Stages Of Schistosoma Mansoni Quantified With Xcelligence Worm Real-Time Motility Assay (Xworm)., Gabriel Rinaldi, Alex Loukas, Paul J. Brindley, Jeff T. Irelan, Michael J. Smout

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Infection with helminth parasites causes morbidity and mortality in billions of people and livestock worldwide. Where anthelmintic drugs are available, drug resistance is a major problem in livestock parasites, and a looming threat to public health. Monitoring the efficacy of these medicines and screening for new drugs has been hindered by the lack of objective, high-throughput approaches. Several cell monitoring technologies have been adapted for parasitic worms, including video-, fluorescence-, metabolism enzyme- and impedance-based tools that minimize the screening bottleneck. Using the xCELLigence impedance-based system we previously developed a motility-viability assay that is applicable for a range of helminth parasites. …

Donor Platelet Plasma Components Inactivate Sensitive And Multidrug Resistant Acinetobacter Baumannii Isolates, Chelsea M. Edelblute, Olga N. Pakhomova, Fanying Li, Barbara Y. Hargrave, Loree C. Heller

Bioelectrics Publications

Acinetobacter baumannii is an environmentally resilient healthcare-associated opportunistic pathogen responsible for infections at many body sites. In the last 10 years, clinical strains resistant to many or all commonly used antibiotics have emerged globally. With few antimicrobial agents in the pharmaceutical pipeline, new and alternative agents are essential. Platelets secrete a large number of proteins, including proteins with antimicrobial activity. In a previous study, we demonstrated that donor platelet supernatants and plasma significantly inhibited the growth of a reference strain of A. baumannii in broth and on skin. This inhibition appeared to be unrelated to the platelet activation state. In …

Investigations Into The Cross-Infectivity Of Nematode Parasites Of Cattle And Sheep, Eva Marie Wray

Graduate Theses and Dissertations

The existence of anthelmintic resistance is not singular in parasite species, host species or geographic region. It has become a problem of worldly stature, especially when considering sheep nematodes. Recommendations have been modified from chemical-based control to multipart, managerial intervention. Compared with nematodes of cattle, the worldwide resistance of sheep nematodes to anthelmintic remedies is much more pronounced and urgent. As the resistance to essentially all anthelmintic classes approaches a cautionary level, the implementation of non-chemical controls has grown increasingly essential. Six-6 to 8 month old Holstein steer calves, six-5 month old Katahdin ram lambs and eight-5 month old Suffolk …

Carcinogenic Liver Fluke Secretes Extracellular Vesicles That Promote Cholangiocytes To Adopt A Tumorigenic Phenotype, Sujittra Chaidayet, Javier Sotillo, Michael Smout, Cinzia Cantacessi, Malcolm Jones, Paul J. Brindley, Jeffrey M. Bethony, +9 Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background. Throughout Asia there is an unprecedented link between cholangiocarcinoma and infection with the liver fluke Opisthorchis viverrini. Multiple processes including chronic inflammation and secretion of parasite proteins into the biliary epithelium drive infection towards cancer. Until now, the mechanism and effects of parasite protein entry into cholangiocytes was unknown.

Methods. Various microscopy techniques were used to identify O. viverrini extracellular vesicles (EVs) and their internalization by human cholangiocytes. Using mass spectrometry we characterised the EV proteome and associated changes in cholangiocytes after EV uptake, and detected EV proteins in bile of infected hamsters and humans. Cholangiocyte proliferation and …

Carcinogenic Parasite Secretes Growth Factor That Accelerates Wound Healing And Potentially Promotes Neoplasia., Michael J. Smout, Javier Sotillo, Thewarach Laha, Atiroch Papatpremsiri, Gabriel Rinaldi, Rafael N. Pimenta, Paul J. Brindley, +11 More

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Infection with the human liver fluke Opisthorchis viverrini induces cancer of the bile ducts, cholangiocarcinoma (CCA). Injury from feeding activities of this parasite within the human biliary tree causes extensive lesions, wounds that undergo protracted cycles of healing, and re-injury over years of chronic infection. We show that O. viverrini secreted proteins accelerated wound resolution in human cholangiocytes, an outcome that was compromised following silencing of expression of the fluke-derived gene encoding the granulin-like growth factor, Ov-GRN-1. Recombinant Ov-GRN-1 induced angiogenesis and accelerated mouse wound healing. Ov-GRN-1 was internalized by human cholangiocytes and induced gene and protein expression changes associated …

Advances In The Diagnosis Of Human Opisthorchiasis: Development Of Opisthorchis Viverrini Antigen Detection In Urine, Chanika Worasith, Christine Kamamia, Anna Yakovleva, Kunyarat Duenngai, Chompunoot Wangboon, Jeffrey M. Bethony, +8 Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Many strategies to control opisthorchiasis have been employed in Thailand, but not in the other neighbouring countries. Specific control methods include mass drug administration (MDA) and health education to reduce raw fish consumption. These control efforts have greatly shifted the epidemiology of Opisthorchis viverrini (OV) infection over the last decade from presenting as densely concentrated "heavy" infections in single villages to widespread "light" OV infections distributed over wide geographical areas. Currently, the "gold standard" detection method for OV infection is formalin ethyl-acetate concentration technique (FECT), which has limited diagnostic sensitivity and diagnostic specificity for light OV infections, with OV …

Whole-Genome Sequencing Of Kshv From Zambian Kaposi’S Sarcoma Biopsies Reveals Unique Viral Diversity, Landon N. Olp, Adrien Jeanniard, Clemence Marimo, John T. West, Charles Wood

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent for Kaposi’s sarcoma (KS). Both KSHV and KS are endemic in sub-Saharan Africa where approximately 84% of global KS cases occur. Nevertheless, whole-genome sequencing of KSHV has only been completed using isolates from Western countries—where KS is not endemic. The lack of whole-genome KSHV sequence data from the most clinically important geographical region, sub-Saharan Africa, represents an important gap as it remains unclear whether genomic diversity has a role on KSHV pathogenesis. We hypothesized that distinct KSHV genotypes might be present in sub-Saharan Africa compared to Western countries. Using a KSHV-targeted enrichment …

Progression Of Non-Alcoholic Steatosis To Steatohepatitis And Fibrosis Parallels Cumulative Accumulation Of Danger Signals That Promote Inflammation And Liver Tumors In A High Fat-Cholesterol-Sugar Diet Model In Mice, Michal Ganz, Terence N. Bukong, Timea Csak, Banishree Saha, Jin-Kyu Park, Aditya Ambade, Karen Kodys, Gyongyi Szabo

Gyongyi Szabo

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is becoming a pandemic. While multiple 'hits' have been reported to contribute to NAFLD progression to non-alcoholic steatohepatitis (NASH), fibrosis and liver cancer, understanding the natural history of the specific molecular signals leading to hepatocyte damage, inflammation and fibrosis, is hampered by the lack of suitable animal models that reproduce disease progression in humans. The purpose of this study was first, to develop a mouse model that closely mimics progressive NAFLD covering the spectrum of immune, metabolic and histopathologic abnormalities present in human disease; and second, to characterize the temporal relationship between sterile/exogenous danger …

Evaluation Of Cardiac Involvement In Children With Dengue By Serial Echocardiographic Studies, Tawatchai Kirawittaya, In-Kyu Yoon, Sineewanlaya Wichit, Sharone Green, Francis A. Ennis, Robert V. Gibbons, Stephen J. Thomas, Alan L. Rothman, Siripen Kalayanarooj, Anon Srikiatkhachorn

Sharone Green

BACKGROUND: Infection with dengue virus results in a wide range of clinical manifestations from dengue fever (DF), a self-limited febrile illness, to dengue hemorrhagic fever (DHF) which is characterized by plasma leakage and bleeding tendency. Although cardiac involvement has been reported in dengue, the incidence and the extent of cardiac involvement are not well defined. METHODS AND PRINCIPAL FINDINGS: We characterized the incidence and changes in cardiac function in a prospective in-patient cohort of suspected dengue cases by serial echocardiography. Plasma leakage was detected by serial chest and abdominal ultrasonography. Daily cardiac troponin-T levels were measured. One hundred and eighty …

Characterization Of The Atsr/Atst Global Regulatory Pathway In Burkholderia Ceocepacia, Maryam Khodai-Kalaki

Electronic Thesis and Dissertation Repository

Phosphorylation cascades governed by two-component signal transduction systems provide key signalling mechanisms in bacteria, simple eukaryotes and higher plants, allowing them to translate signals into adaptive responses. These regulatory pathways consist of a transmembrane sensor protein that responds to an environmental cue leading to autophosphorylation, followed by the transfer of the phosphate to a cytoplasmic response regulator. Here, I study AtsR, a membrane-bound hybrid sensor kinase of Burkholderia cenocepacia, that negatively regulates quorum sensing related virulence factors such as biofilm, type 6-secretion and protease secretion. B. cenocepacia is a Gram-negative opportunistic pathogen which causes severe, chronic respiratory infections in …

The Right Tool For The Job: Detection Of Soil-Transmitted Helminths In Areas Co-Endemic For Other Helminths, Maria V. Periago, Renata C. Diniz, Simone A. Pinto, Anna Yakovleva, Rodrigo Correa-Oliveira, David J. Diemert, Jeffrey M. Bethony

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Due to the recent increased use of the McMaster (MM) fecal egg counting method for assessing benzimidazole drug efficacy for treating soil-transmitted helminth (STH) infections, the aim of the current study was to determine the operational value of including the MM method alongside the Kato-Katz (KK) fecal thick smear to increase the diagnostic sensitivity when STHs are co-endemic with trematode helminths (e.g., Schistosoma mansoni).

Methods

A cross-sectional study was conducted in school-aged children aged 4-18 years in the northeastern region of the State of Minas Gerais (Brazil), where Necator americanus, Ascaris lumbricoides, Trichuris trichiura, and S …

The Spatial Dynamics Of Dengue Virus In Kamphaeng Phet, Thailand, Piraya Bhoomiboonchoo, Robert V. Gibbons, Angkana Huang, In-Kyu Yoon, Darunee Buddhari, Ananda Nisalak, Natkamol Chansatiporn, Mathuros Thipayamongkolgul, Siripen Kalanarooj, Timothy Endy, Alan L. Rothman, Anon Srikiatkhachorn, Sharone Green, Mammen P. Mammen, Derek A. Cummings, Henrik Salje

Sharone Green

BACKGROUND: Dengue is endemic to the rural province of Kamphaeng Phet, Northern Thailand. A decade of prospective cohort studies has provided important insights into the dengue viruses and their generated disease. However, as elsewhere, spatial dynamics of the pathogen remain poorly understood. In particular, the spatial scale of transmission and the scale of clustering are poorly characterized. This information is critical for effective deployment of spatially targeted interventions and for understanding the mechanisms that drive the dispersal of the virus.

METHODOLOGY/PRINCIPAL FINDINGS: We geocoded the home locations of 4,768 confirmed dengue cases admitted to the main hospital in Kamphaeng Phet …

Preliminary Evaluation Of Near Infrared Spectroscopy As A Method To Detect Plasma Leakage In Children With Dengue Hemorrhagic Fever, Babs R. Soller, Anon Srikiatkhachorn, Fengmei Zou, Alan L. Rothman, In-Kyu Yoon, Robert V. Gibbons, Siripen Kalayanarooj, Stephen J. Thomas, Sharone Green

Sharone Green

BACKGROUND: Dengue viral infections are prevalent in the tropical and sub-tropical regions of the world, resulting in substantial morbidity and mortality. Clinical manifestations range from a self-limited fever to a potential life-threatening plasma leakage syndrome (dengue hemorrhagic fever). The objective of this study was to assess the utility of near infrared spectroscopy (NIRS) measurements of muscle oxygen saturation (SmO2) as a possible continuous measure to detect plasma leakage in children with dengue.

METHODS: Children ages 6 months to 15 years of age admitted with suspected dengue were enrolled from the dengue ward at Queen Sirikit National Institute for Child Health. …

Sequential Dengue Virus Infections Detected In Active And Passive Surveillance Programs In Thailand, 1994-2010, Piraya Bhoomiboonchoo, Ananda Nisalak, Natkamol Chansatiporn, In-Kyu Yoon, Siripen Kalayanarooj, Mathuros Thipayamongkolgul, Timothy Endy, Alan L. Rothman, Sharone Green, Anon Srikiatkhachorn, Darunee Buddhari, Mammen P. Mammen, Robert V. Gibbons

Sharone Green

BACKGROUND: The effect of prior dengue virus (DENV) exposure on subsequent heterologous infection can be beneficial or detrimental depending on many factors including timing of infection. We sought to evaluate this effect by examining a large database of DENV infections captured by both active and passive surveillance encompassing a wide clinical spectrum of disease.

METHODS: We evaluated datasets from 17 years of hospital-based passive surveillance and nine years of cohort studies, including clinical and subclinical DENV infections, to assess the outcomes of sequential heterologous infections. Chi square or Fisher's exact test was used to compare proportions of infection outcomes such …

Levels Of 8-Oxodg Predict Hepatobiliary Pathology In Opisthorchis Viverrini Endemic Settings In Thailand., Prasert Saichua, Anna Yakovleva, Christine Kamamia, Amar R. Jariwala, Paul J. Brindley, Jeffrey M. Bethony, + 8 More

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Opisthorchis viverrini is distinct among helminth infections as it drives a chronic inflammatory response in the intrahepatic bile duct that progresses from advanced periductal fibrosis (APF) to cholangiocarcinoma (CCA). Extensive research shows that oxidative stress (OS) plays a critical role in the transition from chronic O. viverrini infection to CCA. OS also results in the excision of a modified DNA lesion (8-oxodG) into urine, the levels of which can be detected by immunoassay. Herein, we measured concentrations of urine 8-oxodG by immunoassay from the following four groups in the Khon Kaen Cancer Cohort study: (1) O. viverrini negative individuals, (2) …

Effects Of Antiretroviral Therapy On Kaposi’S Sarcoma–Associated Herpesvirus (Kshv) Transmission Among Hiv-Infected Zambian Children, Landon Olp, Veenu Minhas, Clement Gondwe, Chipepo Kankasa, Janet M. Wojcicki, Charles Mitchell, John T. West, Charles Wood

Nebraska Center for Virology: Faculty Publications

Background: The risk of Kaposi’s sarcoma–associated herpesvirus (KSHV) acquisition among children is increased by HIV infection. Antiretroviral therapy (ART) was recently made widely available to HIV-infected children in Zambia. However, the impact of early ART on KSHV transmission to HIV-infected children is unknown.

Methods: We enrolled and followed a cohort of 287 HIV-exposed, KSHV-negative children under 12 months of age from Lusaka, Zambia, to identify KSHV seroconversion events. Potential factors associated with KSHV infection—with an emphasis on HIV, ART, and immunological measures—were assessed through structured questionnaires and blood analyses. Incidence rate, Kaplan- Meier, and multivariable Cox regression models were used …

Alcohol And Hcv: Implications For Liver Cancer, Gyongyi Szabo, Banishree Saha, Terence Bukong

Gyongyi Szabo

Liver cancers are one of the deadliest known malignancies which are increasingly becoming a major public health problem in both developed and developing countries. Overwhelming evidence suggests a strong role of infection with hepatitis B and C virus (HBV and HCV), alcohol abuse, as well as metabolic diseases such as obesity and diabetes either individually or synergistically to cause or exacerbate the development of liver cancers. Although numerous etiologic mechanisms for liver cancer development have been advanced and well characterized, the lack of definite curative treatments means that gaps in knowledge still exist in identifying key molecular mechanisms and pathways …

A Novel Human Radixin Peptide Inhibits Hepatitis C Virus Infection At The Level Of Cell Entry, Terence Bukong, Karen Kodys, Gyongyi Szabo

Gyongyi Szabo

Hepatitis C virus infection of hepatocytes is a multistep process involving the interaction between viral and host cell molecules. Recently, we identified ezrin-moesin-radixin proteins and spleen tyrosine kinase (SYK) as important host therapeutic targets for HCV treatment development. Previously, an ezrin hinge region peptide (Hep1) has been shown to exert anti-HCV properties in vivo, though its mechanism of action remains limited. In search of potential novel inhibitors of HCV infection and their functional mechanism we analyzed the anti-HCV properties of different human derived radixin peptides. Sixteen different radixin peptides were derived, synthesized and tested. Real-time quantitative PCR, cell toxicity assay, …

The Genetics Of Hepatitis C Virus Underlie Its Ability To Escape Humoral Immunity, Jay Kolls, Gyongyi Szabo

Gyongyi Szabo

Hepatitis C virus (HCV) is a leading cause of chronic liver disease, and efforts to develop therapeutic vaccine strategies have been limited by immune escape due to HCV variants that are resistant to current vaccines or HCV variants that rapidly acquire new resistance-conferring mutations. Recently, the crystal structure of the viral envelope protein E2 region was resolved as well as how E2 docks to the host CD81 protein; therefore, antibodies that block this interaction should prevent viral entry into host cells. In this issue of the JCI, Bailey and colleagues show that immune escape of HCV can occur by naturally …

Expert–Novice Differences In Mental Models Of Viruses, Vaccines, And The Causes Of Infectious Disease, Benjamin D. Jee, David H. Uttal, Amy N. Spiegel, Judy Diamond

Amy N. Spiegel

Humans are exposed to viruses everywhere they live, play, and work. Yet people’s beliefs about viruses may be confused or inaccurate, potentially impairing their understanding of scientific information. This study used semi-structured interviews to examine people’s beliefs about viruses, vaccines, and the causes of infectious disease. We compared people at different levels of science expertise: middle school students, teachers, and professional virologists. The virologists described more entities involved in microbiological processes, how these entities behaved, and why. Quantitative and qualitative analyses revealed distinctions in the cognitive organization of several concepts, including infection and vaccination. For example, some students and teachers …

Alcohol-Induced Mir-27a Regulates Differentiation And M2 Macrophage Polarization Of Normal Human Monocytes, Banishree Saha, Johanna Bruneau, Karen Kodys, Gyongyi Szabo

Gyongyi Szabo

Alcohol abuse is a leading cause of liver disease characterized by liver inflammation, fatty liver, alcoholic hepatitis, or liver cirrhosis. Immunomodulatory effects of alcohol on monocytes and macrophages contribute to alcoholic liver disease. Alcohol use, an independent risk factor for progression of hepatitis C virus (HCV) infection-mediated liver disease, impairs host defense and alters cytokine production and monocyte/macrophage activation. We hypothesized that alcohol and HCV have synergistic effects on the phenotype and function of monocytes. Our data show that acute alcohol binge drinking in healthy volunteers results in increased frequency of CD16(+) and CD68(+) and M2-type (CD206(+), dendritic cell [DC]-SIGN(+)-expressing …

Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf

Electronic Thesis and Dissertation Repository

The pleiotropic cytokine granulocyte-colony stimulatory factor (G-CSF) is mainly required for the generation of neutrophils, but its role in macrophage generation has also been reported. In addition, G-CSF is effective for the down-regulation of inflammatory cytokines and ameliorating gut disorders, such as colitis. However, the G-CSF function in macrophage generation and gut immunity remains unclear. The first focus of this thesis was to assess the role of G-CSF in macrophage generation and its contribution to gut immunity. G-CSF was found to promote the generation of Gr-1high/F4/80+ macrophages in macrophage (M)-CSF-treated bone marrow cells, most likely through suppressing cell death. Gr-1high …

Src Homology 2 Domain-Containing 5’-Inositol Phosphatase-2 (Ship2) Is An Effector Of Lymphatic Dysfunction, Germaine D. Agollah

Dissertations & Theses (Open Access)

The lymphatic system is essential for the transport of excess fluid, protein, and foreign materials from interstitial tissues to lymph nodes; for immune surveillance, and to maintain fluid homeostasis. Dysregulated lymphatics can be attributed to pathological conditions including tumor metastasis, inflammation, chronic wounds, obesity, blood vascular disorders, and lymphedema. Of these, lymphedema is the most extreme of lymphatic disorders and is represented by a spectrum of symptoms ranging from mild, subtle presentation to severe, disfiguring, overt presentation. Lymphedema is more manageable in the early stages of disease but severely reduces quality of life with progression. Due to lack of molecular …
