Freshwater Fungal Infections, Dennis J. Baumgardner 2017 Aurora UW Medical Group, Aurora Health Care

Freshwater Fungal Infections, Dennis J. Baumgardner

Dennis J. Baumgardner. MD

Fungal infections as a result of freshwater exposure or trauma are fortunately rare. Etiologic agents are varied, but commonly include filamentous fungi and Candida. This narrative review describes various sources of potential freshwater fungal exposure and the diseases that may result, including fungal keratitis, acute otitis externa and tinea pedis, as well as rare deep soft tissue or bone infections and pulmonary or central nervous system infections following traumatic freshwater exposure during natural disasters or near-drowning episodes. Fungal etiology should be suspected in appropriate scenarios when bacterial cultures or molecular tests are normal or when the infection worsens or fails ...

Dynamic Host-Pathogen Interactions Result In Fungal Epitope Unmasking, Alex Hopke 2016 University of Maine

Dynamic Host-Pathogen Interactions Result In Fungal Epitope Unmasking, Alex Hopke

Electronic Theses and Dissertations

Molecular camouflage is used by a diverse set of pathogens to disguise their identity and avoid recognition by protective host receptors. The opportunistic fungal pathogen Candida albicans is a good example, as it masks the inflammatory component β-glucan in its cell wall to evade detection by the immune receptor Dectin-1. Interestingly, it has been seen that β-glucan becomes unmasked during infection in vivo, though the underlying mechanisms remained unclear. Exposure levels of this epitope may be important, as Dectin-1 mediates protection from some strains of C. albicans and alterations in the organization and composition of the Candida cell wall can ...

Geodemographic Features Of Human Blastomycosis In Eastern Wisconsin, Megan E. Huber, Dennis J. Baumgardner, Jessica J. F. Kram, Melissa A. Lemke 2016 Aurora Research Institute, Aurora Health Care

Geodemographic Features Of Human Blastomycosis In Eastern Wisconsin, Megan E. Huber, Dennis J. Baumgardner, Jessica J. F. Kram, Melissa A. Lemke

Dennis J. Baumgardner. MD

Purpose

Blastomycosis is an endemic fungal infection. In rural northern Wisconsin, blastomycosis cases are associated with certain environmental features including close proximity to waterways. Other studies have associated blastomycosis with particular soil chemicals. However, blastomycosis also occurs in urban and suburban regions. We explored the geodemographic associations of blastomycosis cases in the more urban/suburban landscape of eastern Wisconsin.

Methods

We conducted a retrospective study of 193 laboratory-identified blastomycosis cases in a single eastern Wisconsin health system, 2007–2015. Controls were 250 randomly selected cases of community-diagnosed pneumonia from a similar time period. Geographic features of home addresses were explored ...

Pulmonary Blastomycosis In Vilas County, Wisconsin: Weather, Exposures And Symptoms, Dennis J. Baumgardner, Kiley A. Bernhard, Gina Egan

Dennis J. Baumgardner. MD

Purpose

Blastomycosis is a serious fungal infection contracted by inhalation of Blastomyces spores from the environment. Case occurrence in dogs in Vilas County, Wisconsin, has been associated with antecedent weather. We aimed to explore the effects of weather on the occurrence of human pulmonary blastomycosis in this area, and update exposure factors and symptoms since last published reports.

Methods

Mandatory case reports were reviewed. Chi-square test was used for categorical data of exposures, comparing 1979–1996 (n=101) versus 1997–June 2013 (n=95). Linear regression was used to model local weather data (available 1990–2013; n=126); Southern Oscillation ...


Sex-Specific Fungal Communities Of The Dioicous Moss Ceratodon Purpureus, Mehmet Ali Balkan 2016 Portland State University

Sex-Specific Fungal Communities Of The Dioicous Moss Ceratodon Purpureus, Mehmet Ali Balkan

Dissertations and Theses

Mosses display a number of hallmark life history traits that influence their ecology at the population and community level. The long lived separation of sexes observed in the haploid gametophyte (dioicy) is one such feature of particular importance, as it is observed in the majority of bryophytes and creates intraspecific specialization of male and female individuals.

The prevalence of sexually dimorphic mosses raises the possibility of sex-specific interactions with fungi as observed in some vascular plants. Here I investigated how moss sex shapes fungal communities associated with gametophytic tissues of the ubiquitous moss, Ceratodon purpureus. Using greenhouse populations of C ...

Corn Fungicides: To Spray Or Not To Spray?, Alison E. Robertson, John M. Shriver 2015 Iowa State University

Corn Fungicides: To Spray Or Not To Spray?, Alison E. Robertson, John M. Shriver

Integrated Crop Management News

Across the state of Iowa, much of the crop is reaching V5 to V6 and thoughts of an early fungicide application have probably crossed some people’s minds. Every year, we evaluate and compare registered fungicides applied at either V5 to V6, R1 alone, or At V5 to V6 plus R1 for foliar disease management and effects on yield. In 2014, we tested 8 products at 6 locations in Iowa (Table 1). A randomized complete block design with 4 replications was used. At each location, two non-sprayed checks were included.

Soybean Seedling Damage: Is There An Interaction Between The Ilevo Seed Treatment And Pre-Emergence Herbicides?, Kiersten Wise, Daren S. Mueller, Yuba Kandel, Bryan Young, Bill Johnson, Travis Legleiter

Integrated Crop Management News

Farmers who were lucky enough to plant soybeans and spray pre-emergence herbicides in between rain events may now be seeing discolored or injured seedlings. Reports of fields with these issues are widespread across Indiana, Iowa, and surrounding areas, and many farmers and crop advisors are questioning if damage is more severe when pre-emergence herbicides are applied to fields that have been planted with seed treated with the new fluopyram fungicide seed treatment ILeVO.


Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, Mallory J. Suhr 2015 University of Nebraska-Lincoln

Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, Mallory J. Suhr

Dissertations, Theses, & Student Research in Food Science and Technology

Gastrointestinal microbiome studies have failed to include fungi in total community analyses. As a result, their diversity and function in the gut is poorly understood. Recent work has begun to uncover the role intestinal fungi play in diet, immune system development, interactions with other microorganisms in the gut, and pathogenesis of diseases. Advances in sequencing technologies allow for the ability to profile the fungal gut microbiome (“mycobiome”) in healthy and diseased states. This thesis explores the mycobiome in 1) healthy humans with a vegetarian diet and 2) pediatric small bowel transplant recipients that develop fungal bloodstream infections.

The gut mycobiome ...


Identification Of Transcription Factors Gzf3, Rfx1, Orf19.3928 As Being Implicated In Candida-Bacterial Interactions., Joni Watson 2015 East Tennessee State University

Identification Of Transcription Factors Gzf3, Rfx1, Orf19.3928 As Being Implicated In Candida-Bacterial Interactions., Joni Watson

Undergraduate Honors Theses

Candida albicans is an opportunistic pathogen that is present in the normal flora in a majority of individuals. One key factor in C. albicans virulence is the ability to change its morphology from yeast to an elongated or hyphal form. The regulation of this morphogenesis relies in part upon quorum sensing (QS) molecules. C. albicans often exists as part of a mixed culture alongside other microbes and is influenced by their presence as well as the presence of QS molecules that they produce. In this study, a library of diploid homozygous transcriptional regulator knockout (TRKO) mutants were screened to identify ...


Potential Role Of Rta3 And Gnp3 Transport Genes In The Quorum Sensing Response Of Candida Albicans, John G. Magnuson 2015 East Tennessee State University

Potential Role Of Rta3 And Gnp3 Transport Genes In The Quorum Sensing Response Of Candida Albicans, John G. Magnuson

Undergraduate Honors Theses

Quorum sensing (QS) is a mechanism of communication between cells to coordinate biological activities. In the opportunistic fungal pathogen Candida albicans, QS is important for regulating the organism’s ability to change morphology from a yeast form to a hyphal form. Previously, our laboratory identified several genes involved in polymicrobial communication between C. albicans and three bacterial species. We hypothesize that interspecies communication and QS utilize the same genetic pathways to control C. albicans morphological behavior. In this study, two transport genes, RTA3 and GNP3, and their involvement in QS were examined. To test whether these two genes participate in ...

Effectiveness Of Foliar Fungicides By Timing On Northern Leaf Blight On Hybrid Corn In Southwest Iowa, Alison Robertson, Bernie Havlovic, Dan Schaben

Iowa State Research Farm Progress Reports

Fungicide use on hybrid corn has increased considerably, primarily due to reports of increased yields, even in the absence of disease and higher corn prices. A number of fungicides are registered for use on corn. The objectives of this project were to 1) assess the effect of timing of application of fungicides on disease, 2) evaluate the yield response of hybrid corn to foliar fungicide application, and 3) discern differences, if any, between fungicide products.
