An Investigation Into The Prevalence Of Vancomycin-Resistant Enterococci Within An Irish Hospital, Dylan Casey

International Undergraduate Journal of Health Sciences

Vancomycin-resistant enterococci (VRE) are well-recognised nosocomial pathogens that pose a significant threat to public health. Associated with poorer clinical outcomes than their vancomycin-sensitive counterparts, the prevalence of VRE in Ireland has increased in recent times, with the European Antimicrobial Resistance Surveillance Network reporting that out of 29 countries, Ireland demonstrated the highest rates of vancomycin resistance among invasive Enterococcus faecium isolates between 2011 and 2014 (2011; 34.9%, 2012; 44.0%, 2013; 42.7%, 2014; 45.1%). Herein, we investigate VRE prevalence in the Mercy University Hospital (MUH) – an acute care hospital in southern Ireland. A total of 21 first-time ...


Sepa Enhances Shigella Invasion Of Epithelial Cells By Degrading Alpha-1 Antitrypsin And Producing A Neutrophil Chemoattractant, Mario Meza-Segura, James R. Birtley, Ana Maldonado-Contreras, Christian Mueller, Karl J. Simin, Lawrence J. Stern, Beth A. Mccormick Dec 2021

Sepa Enhances Shigella Invasion Of Epithelial Cells By Degrading Alpha-1 Antitrypsin And Producing A Neutrophil Chemoattractant, Mario Meza-Segura, James R. Birtley, Ana Maldonado-Contreras, Christian Mueller, Karl J. Simin, Lawrence J. Stern, Beth A. Mccormick

UMass Center for Clinical and Translational Science Supported Publications

Shigella spp. are highly adapted pathogens that cause bacillary dysentery in human and nonhuman primates. An unusual feature of Shigella pathogenesis is that this organism invades the colonic epithelia from the basolateral pole. Therefore, it has evolved the ability to disrupt the intestinal epithelial barrier to reach the basolateral surface. We have shown previously that the secreted serine protease A (SepA), which belongs to the family of serine protease autotransporters of Enterobacteriaceae, is responsible for the initial destabilization of the intestinal epithelial barrier that facilitates Shigella invasion. However, the mechanisms used by SepA to regulate this process remain unknown. To ...

International Journal of Speleology

The characterization of the most common photosynthetic biofilms in the Nerja Cave by the continuous monitoring of the in vivo chlorophyll a (Chl a) fluorescence and the incorporation of the irradiance as a new environmental variable related to previous studies in the cave, have allowed us to improve our knowledge about the photosynthetic pattern of the biofilms of the cave. Effective quantum yield (ΔF/Fm) and relative electron transport rate (rETR) were determined during periods of the light, whereas the maximal quantum yield (Fv /Fm) was determined during dark periods. Increases in the photosynthetic yields and productivity ...

Determining Effects Of Management Practices On Potato Early Dying And Soil Microbiome And Assessing Risk Of Fungicide Resistance In Verticillium Dahliae, Kedi Li

Electronic Theses and Dissertations

Potato early dying (PED) is a yield-constraining soilborne disease of potato, caused by Verticillium spp. with V. dahliae being the predominant causal agent. Since the pathogen inhabits soil for long periods, PED management aims to reduce the population of V. dahliae in soil. Benzovindiflupyr and azoxystrobin are effective chemicals and frequently used in the control of V. dahliae. In this study, field trials were conducted at Aroostook Farm, Presque Isle, ME in 2019 and 2020. Chemical and biological products have been studied for PED control, and fungicide resistance was also examined. To evaluate fungicide resistance, benzovindiflupyr was characterized on sensitivity ...


Metabolic Heterogeneity And The Roles Of Cody And Ccpa In Central Metabolism And S. Aureus Biofilm Formation., Logan L. Bulock Dec 2021

Metabolic Heterogeneity And The Roles Of Cody And Ccpa In Central Metabolism And S. Aureus Biofilm Formation., Logan L. Bulock

Theses & Dissertations

Staphylococcus aureus is a metabolically versatile human pathogen, causing disease in many areas of the body. Its versatility can be attributed to the fact that it utilizes a variety of tools to adapt to many different environments, including toxins to scavenge from the host and multiple transporters to compete for its preferred carbon sources. S. aureus can also survive in harsh conditions through biofilm development, which are notoriously recalcitrant to antibiotics and immune defenses. Biofilms exhibit marked heterogeneity, with division of labor for production of matrix components and differential gene expression among various niches within the biofilm.

In this study ...


High-Affinity, Neutralizing Antibodies To Sars-Cov-2 Can Be Made Without T Follicular Helper Cells, Jennifer S. Chen, Gowthaman Uthaman, Craig B. Wilen, Stephanie C. Eisenbarth Dec 2021

High-Affinity, Neutralizing Antibodies To Sars-Cov-2 Can Be Made Without T Follicular Helper Cells, Jennifer S. Chen, Gowthaman Uthaman, Craig B. Wilen, Stephanie C. Eisenbarth

COVID-19 Publications by UMass Chan Authors

T follicular helper (Tfh) cells are the conventional drivers of protective, germinal center (GC)-based antiviral antibody responses. However, loss of Tfh cells and GCs has been observed in patients with severe COVID-19. As T cell-B cell interactions and immunoglobulin class switching still occur in these patients, non-canonical pathways of antibody production may be operative during SARS-CoV-2 infection. We found that both Tfh-dependent and -independent antibodies were induced against SARS-CoV-2 infection, SARS-CoV-2 vaccination, and influenza A virus infection. Even though Tfh-independent antibodies to SARS-CoV-2 had evidence of reduced somatic hypermutation, they were still high-affinity, durable, and reactive against diverse spike-derived ...


Spatial Variability In Streambed Microbial Community Structure Across Two Watersheds, Philips Akinwole, Jinjun Kan, Louis A. Kaplan, Robert H. Findlay Dec 2021

Spatial Variability In Streambed Microbial Community Structure Across Two Watersheds, Philips Akinwole, Jinjun Kan, Louis A. Kaplan, Robert H. Findlay

Biology Faculty publications

Both spatial and temporal variability are key attributes of sedimentary microbial communities, and while spatial effects on beta-diversity appear to dominate at larger distances, the character of spatial variability at finer scales remains poorly understood, especially for headwater stream communities. We investigated patterns of microbial community structure (MCS) in biofilms attached to streambed sediments from two watersheds across spatial scales spanning ,1 m within a single stream to several hundred kilometers between watersheds. Analyses of phospholipid fatty acid (PLFA) profiles indicated that the variations in MCS were driven by increases in the relative abundance of microeukaryotic photoautotrophs and their contribution ...


Virology: Mutagenizing The Proteolytic Cleavage Site In The Major Capsid Protein In Ssv1, Thejanee Liyanaarachchi Dec 2021

Virology: Mutagenizing The Proteolytic Cleavage Site In The Major Capsid Protein In Ssv1, Thejanee Liyanaarachchi

University Honors Theses

SSV1, spindle-shaped virus 1, is an archaeal virus with a unique shape that belongs to the family of fuselloviruses and infects hyperthermophilic archaea that thrive at 80°C and pH 3. SSV1 has two capsid proteins, VP1 and VP3, that presumably produce the lemon-shaped virion structure characteristic of fuselloviruses. The VP1 amino acid sequence is highly conserved among SSVs. Here, we investigate the importance of the proteolytic cleavage site in position E66 in VP1 by changing its glutamic acid to the other 19 amino acids. We have developed a new protocol for creating SSV1 mutants through HiFi Assembly (NEB) to ...

Evaluating The Effects Of Pine And Miscanthus Biochar On Water Activity And Escherichia Coli Populations In Commercial Broiler Litter, Christopher Austin Marty

Theses and Dissertations

The decrease in subtherapeutic antibiotic administration in poultry has increased the need to address production challenges caused by pathogens, such as E. coli. One potential way to improve bird health and reduce bacterial infection is through the addition of litter amendments that absorb moisture. Biochar (BC) has previously been shown to increase water holding capacity in poultry litter, but its effects on E. coli mitigation are unknown. The objectives of this research were to 1) evaluate water activity of poultry litter amended with pine and miscanthus BC, and 2) determine the effects of different BC inclusion rates on litter E ...


Soil Microbial Community Dynamics In Response To Prescribed Extreme Fires Following Juniperus Virginiana Invasion In The Loess Canyons Of Nebraska, Julie A. Fowler Dec 2021

Soil Microbial Community Dynamics In Response To Prescribed Extreme Fires Following Juniperus Virginiana Invasion In The Loess Canyons Of Nebraska, Julie A. Fowler

Dissertations & Theses in Natural Resources

In Nebraska and other regions of the Great Plains, the conifer Juniperus virginiana (eastern redcedar) is converting grasslands to dense woodlands. This is driven by the interacting drivers of fire suppression, altered grazing regimes, climate change and other anthropogenic factors, impacting the provisioning of ecosystem services. This vegetation state transition modifies water resource regulation and biogeochemical cycles leading to altered edaphic properties including soil microbial community composition. To restore these grasslands and control J. virginiana spread, prescribed extreme burns are implemented as a management tool through local prescribed burn associations. We hypothesized that the alternative state transition to dense J ...

Trained Immunity Enhances The Immune Response And Maintains Microbiome Diversity In Aging And Sepsis, P. Spencer Gill Dec 2021

Trained Immunity Enhances The Immune Response And Maintains Microbiome Diversity In Aging And Sepsis, P. Spencer Gill

Electronic Theses and Dissertations

The global population is rapidly aging. It is estimated that over the next thirty years, the number of individuals >60 years of age will increase by over a billion, and the number of individuals over age 80 may increase by 300 million. As humans age, our immune system becomes progressively weaker through a process called immune senescence. This age-related decrease in immune function increases susceptibility to infection and chronic diseases. Sepsis is a leading cause of death worldwide. Over the past two decades, there has been an increased incidence of sepsis which is due, in part, to our aging population ...


Probiotic Intervention Improves Recovery Of Hippocampal Memory And Hippocampal Atrophy Following Disruption From High-Fat Diet In Adult Rats, Sanyourah A. El-Hulu Dec 2021

Probiotic Intervention Improves Recovery Of Hippocampal Memory And Hippocampal Atrophy Following Disruption From High-Fat Diet In Adult Rats, Sanyourah A. El-Hulu

Honors Theses

Presently, lifestyle factors such as chronic high-fat diet (HFD) consumption occurs concomitantly with weight gain and obesity (Gil-Cardoso et al., 2017; Stranahan et al., 2008). In turn, obesity has been associated with impairments to mental functioning, specifically to memory. Human epidemiological studies show that HFD intake containing saturated, and omega-6-fatty acids is associated with worse performance on a cognitive task whereas a lower fat diet containing omega-3-fatty acids is associated with a protective effect against cognitive decline (Zhang et al., 2006; Uranga et al., 2010). One explanation for this is the critical role of the gut bacteria in brain health ...

Deciphering The Role Of Hsp110 Chaperones In Diseases Of Protein Misfolding, Unekwu M. Yakubu Dec 2021

Deciphering The Role Of Hsp110 Chaperones In Diseases Of Protein Misfolding, Unekwu M. Yakubu

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Molecular chaperones maintain protein homeostasis (proteostasis) by ensuring the proper folding of polypeptides. Loss of proteostasis has been linked to the onset of numerous neurodegenerative disorders including Alzheimer’s, Parkinson’s, and Huntington’s disease. Hsp110 is a member of the Hsp70 class of molecular chaperones and acts as a nucleotide exchange factor (NEF) for Hsp70, the preeminent Hsp70-family protein folding chaperone. Hsp110 promotes rapid cycling of ADP for ATP, allowing Hsp70 to properly fold nascent or unfolded polypeptides in iterative cycles. In addition to its NEF activity, Hsp110 possesses an Hsp70-like substrate binding domain (SBD) whose biological roles are ...


Characterizing Long Covid: Deep Phenotype Of A Complex Condition, Rachel R. Deer, Feifan Liu, Melissa A. Haendel, Peter N. Robinson Dec 2021

Characterizing Long Covid: Deep Phenotype Of A Complex Condition, Rachel R. Deer, Feifan Liu, Melissa A. Haendel, Peter N. Robinson

COVID-19 Publications by UMass Chan Authors

BACKGROUND: Numerous publications describe the clinical manifestations of post-acute sequelae of SARS-CoV-2 (PASC or "long COVID"), but they are difficult to integrate because of heterogeneous methods and the lack of a standard for denoting the many phenotypic manifestations. Patient-led studies are of particular importance for understanding the natural history of COVID-19, but integration is hampered because they often use different terms to describe the same symptom or condition. This significant disparity in patient versus clinical characterization motivated the proposed ontological approach to specifying manifestations, which will improve capture and integration of future long COVID studies.

METHODS: The Human Phenotype Ontology ...


Glycan Functionalization Of Iron Oxide Nanoparticles (Ionps) As A Method Of Inactivating Antibiotic Resistant Neisseria Gonorrhoeae Via A Magnetically Mediated Energy Delivery (Magmed) System, Cedric Taylor Dec 2021

Glycan Functionalization Of Iron Oxide Nanoparticles (Ionps) As A Method Of Inactivating Antibiotic Resistant Neisseria Gonorrhoeae Via A Magnetically Mediated Energy Delivery (Magmed) System, Cedric Taylor

All Theses

With the increase of antibiotic resistant bacteria, current established therapeutic treatment methods are rapidly demonstrating decreasing efficacy. For this project, we are studying a novel alternate mechanism of treating antibiotic resistant bacteria by utilizing magnetic iron oxide nanoparticles (IONPs) coated with a heterobifunctional polyethylene glycol polymer (PEG) and functionalized with glycan structures that can interact with Neisseria gonorrhoeae FA1090. Interaction between the IONPs and bacteria is manipulated by an external alternating magnetic field (AMF) in a process known as magnetically mediated energy delivery (MagMED). Magnetic IONPs were synthesized and reacted with PEG (PEG-IONPs) and functionalized with glycans Gal(α1-3)Gal ...


Response Of Soil Viral And Microbial Functional Diversity To Long-Term Agricultural Management In Jackson, West Tennessee, Ning Duan Dec 2021

Response Of Soil Viral And Microbial Functional Diversity To Long-Term Agricultural Management In Jackson, West Tennessee, Ning Duan

Doctoral Dissertations

Soil microbial communities are a critical component for ecosystem stability and function. Viruses, as an important biotic controller, have the potential to regulate the abundance and diversity of bacterial communities through infection. Soil is known to harbor abundant and diverse viral assemblages but their ecological role and influence on microbial processes has not been fully elucidated. Microbes can be influenced by viruses not only from infection but though biogeochemical feedbacks of the “microbial (bacterium–phage–DOC) loop” or “viral shunt”. However, we know relatively little about the microbial community and function under the regulation of viruses in soil and how ...


Determining The Ecological And Physiological Factors Contributing To The Competitive Success Of Prochlorococcus In The Oligotrophic Ocean, Benjamin C. Calfee Dec 2021

Determining The Ecological And Physiological Factors Contributing To The Competitive Success Of Prochlorococcus In The Oligotrophic Ocean, Benjamin C. Calfee

Doctoral Dissertations

Prochlorococcus is a genus of extremely successful marine cyanobacteria. This success is realized through its pervasive biogeographical range and presence in almost all open ocean environments where it usually it the dominant phytoplankton. Limited capabilities of culturing and genetic manipulation of this organism have resulted in assumptions about this success overwhelmingly based on field observations. These studies have assumed adaptations for resource uptake and utilization in nutrient limited environments to cause dominance of Prochlorococcus over other photosynthetic microbes. In an attempt to definitively explain this through laboratory culture, we developed a culturing system to assay questions of nutrient limitation effects ...


High Arctic Permafrost Microbial Characterizations: Siberian And Svalbard Microbiology Of Ancient And Active Layer Permafrost, Katie Sipes Dec 2021

High Arctic Permafrost Microbial Characterizations: Siberian And Svalbard Microbiology Of Ancient And Active Layer Permafrost, Katie Sipes

Doctoral Dissertations

Permafrost is soil that has remained frozen for at least two years. The active layer is a surface portion above the permafrost that experiences seasonal thaw and refreezing. The environmental characteristics of permafrost and active layer are different but are directly related to each other. As the climate continues to warm, the active layer will expand into the permafrost and the continuously frozen soil will be subjected to seasonal thawing. The organisms that inhabit both the active layer and the permafrost soil will respond differently to the climate based on where in the soil they are present and the soil ...


Microbial Community Dynamics Of A Microcystis Bloom, Helena Pound Dec 2021

Microbial Community Dynamics Of A Microcystis Bloom, Helena Pound

Doctoral Dissertations

Harmful algal bloom events are notoriously associated with massive economic and environmental consequences, causing wildlife and human health risks. As these blooms increase in occurrence, duration, and severity around the world, it is essential to understand conditions leading to bloom formation and why they persist. Abiotic factors such as nutrients are commonly considered in bloom dynamics, but biotic interactions with co-occurring microbial species and viruses must also be taken into account. Harmful algal blooms dominated by the cyanobacterial genus Microcystis occur in bodies of water around the world and provide an ideal system in which to study top-down controls on ...


Mechanisms Of Stress Survival In Gram Positive Bacterial Pathogens, Asia Poudel Dec 2021

Mechanisms Of Stress Survival In Gram Positive Bacterial Pathogens, Asia Poudel

Chemistry & Biochemistry Theses & Dissertations

Anaerobic Gram-positive bacteria are not a well-characterized group but include many human pathogens that are resilient against stresses caused by the human immune system or by antibiotic treatment. This dissertation investigated the survival mechanisms of two clinically relevant Gram-positive organisms, Clostridioides difficile and Cutibacterium acnes under extracellular stresses. The response of the opportunistic skin pathogen Cutibacterium acnes to nanosecond electric pulses is characterized and found that growth in a biofilm, which usually protects bacteria from stress, renders this species more killable by this treatment. In addition, the stringent response (SR), a conserved bacterial stress survival mechanism, is studied in the ...


Kshv Susceptibility And Transmission Within Tonsillar Specimens, Farizeh Aalam Dec 2021

Kshv Susceptibility And Transmission Within Tonsillar Specimens, Farizeh Aalam

Pharmaceutical Sciences (PhD) Dissertations

Despite nearly three decades of research, not much is known regarding the early stages of development for KSHV lymphoproliferative disorders, hindering our ability to develop prophylactic measures or effective treatments. This dissertation will focus on the host and viral factors influencing the magnitude and dynamics of KSHV infection in the human tonsil to pave the way for future interventions directed at limiting person-to-person transmission of KSHV.

To understand the contribution of host factors to KSHV susceptibility in B lymphocytes, we generated a library of 40 tonsillar specimens. Our results indicate that the immunological composition of tonsillar lymphocytes varies across our ...


Impact Of Probiotics On Black Soldier Fly Larvae Transmission Of Stenotrophomonas Maltophilia, Emily Marie Mclaughlin Dec 2021

Impact Of Probiotics On Black Soldier Fly Larvae Transmission Of Stenotrophomonas Maltophilia, Emily Marie Mclaughlin

Honors College

Stenotrophomonas maltophilia is an opportunistic pathogen which can cause a variety of infections, especially in immunocompromised individuals. It has recently been found that black soldier flies can act as carriers for S. maltophilia (Callegari et al., 2020). I have investigated how probiotics impact their vector capabilities. Black soldier fly larvae have been fed substrate spiked with S. maltophilia. After several days of feeding, the larvae were investigated by PCR and plating (Sveensson-Stadler et al., 2011). Two groups of larvae were fed with potatoes infected with S. maltophilia. Persistence of S. maltophilia was determined using PCR by taking samples from days ...


Examination Of The Association Between C - Reactive Protein(Crp) And Covid-19 Infection Severity And Length Of Hospitalization, Abdulahi Aremu Ayanwale Dec 2021

Examination Of The Association Between C - Reactive Protein(Crp) And Covid-19 Infection Severity And Length Of Hospitalization, Abdulahi Aremu Ayanwale

Open Access Theses & Dissertations

Chronic stress can lead to many systemic complications and low-grade systemic inflammation including increased levels of inflammatory cytokines, such as C-reactive protein (CRP). CRP is a marker of systemic inflammation and is associated with depression and perceived stress. Elevations can result in ineffective immune responses, thereby increasing the risk of complications and mortality from infections. Recent evidence suggests that uncontrolled inflammatory responses associated with COVID 19 are a major determinant of disease severity.  The COVID 19 is transmitted from one person to another through droplets from coughing, sneezing, talking, touching droplets on surfaces and contamination by hand-to-mouth routes. The mechanism ...
