Inclusion Of Fermented Foods In Food Guides Around The World, Stephanie N. Chilton, Jeremy P. Burton, Gregor Reid

Microbiology & Immunology Publications

Fermented foods have been a well-established part of the human diet for thousands of years, without much of an appreciation for, or an understanding of, their underlying microbial functionality, until recently. The use of many organisms derived from these foods, and their applications in probiotics, have further illustrated their impact on gastrointestinal wellbeing and diseases affecting other sites in the body. However, despite the many benefits of fermented foods, their recommended consumption has not been widely translated to global inclusion in food guides. Here, we present the case for such inclusion, and challenge health authorities around the world to consider …

An Improved Method For Generating Axenic Entomopathogenic Nematodes., Shruti Yadav, Upasana Shokal, Steven Forst, Ioannis Eleftherianos

Microbiology, Immunology, and Tropical Medicine Faculty Publications

BACKGROUND: Steinernema carpocapsae are parasitic nematodes that invade and kill insects. The nematodes are mutualistically associated with the bacteria Xenorhabdus nematophila and together form an excellent model to study pathogen infection processes and host anti-nematode/antibacterial immune responses. To determine the contribution of S. carpocapsae and their associated X. nematophila to the successful infection of insects as well as to investigate the interaction of each mutualistic partner with the insect immune system, it is important to develop and establish robust methods for generating nematodes devoid of their bacteria.

FINDINGS: To produce S. carpocapsae nematodes without their associated X. nematophila bacteria, we …

Of Monkeys And Men: Immunomic Profiling Of Sera From Humans And Non-Human Primates Resistant To Schistosomiasis Reveals Novel Potential Vaccine Candidates., Mark S Pearson, Luke Becker, Patrick Driguez, Neil D Young, Soraya Gaze, Jeffrey M. Bethony, +12 Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Schistosoma haematobium affects more than 100 million people throughout Africa and is the causative agent of urogenital schistosomiasis. The parasite is strongly associated with urothelial cancer in infected individuals and as such is designated a group I carcinogen by the International Agency for Research on Cancer. Using a protein microarray containing schistosome proteins, we sought to identify antigens that were the targets of protective IgG1 immune responses in S. haematobium-exposed individuals that acquire drug-induced resistance (DIR) to schistosomiasis after praziquantel treatment. Numerous antigens with known vaccine potential were identified, including calpain (Smp80), tetraspanins, glutathione-S-transferases, and glucose transporters (SGTP1), as well …

The Carcinogenic Liver Fluke Opisthorchis Viverrini Is A Reservoir For Species Of Helicobacter., Raksawan Deenonpoe, Chariya Chomvarin, Chawalit Pairojkul, Yaowalux Chamgramol, Alex Loukas, Paul J. Brindley, Banchob Sripa

Microbiology, Immunology, and Tropical Medicine Faculty Publications

There has been a strong, positive correlation between opisthorchiasis-associated cholangiocarcinoma and infection with Helicobacter. Here a rodent model of human infection with Opisthorchis viverrini was utilized to further investigate relationships of apparent co-infections with O. viverrini and H. pylori. A total of 150 hamsters were assigned to five groups: i) Control hamsters not infected with O. viverrini; ii) O. viverrini-infected hamsters; iii) non-O. viverrini infected hamsters treated with antibiotics (ABx); iv) O. viverrini-infected hamsters treated with ABx; and v) O. viverrini-infected hamsters treated both with ABx and praziquantel (PZQ). Stomach, gallbladder, liver, colonic tissue, colorectal feces and O. viverrini worms …

Comparison Of Findings Using Ultrasonography And Cystoscopy In Urogenital Schistosomiasis In A Public Health Centre In Rural Angola, Julio Santos, Jacinta Chaves, Heriberto Araujo, Nuno Vale, Jose Manuel Costa, Paul J. Brindley, Carlos Lopes, Jean Naples, Clive Shiff, Jorge Dupret, Lucio Lara Santos

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background. Schistosomiasis is a chronic disease caused by infection with parasitic worms of the genus Schistosoma. In sub-Saharan Africa, infections with S. haematobium are most common. Cystoscopic examination (CE) has been accepted as the gold-standard test for detecting the late manifestations of schistosomiasis, including urothelial cancer of the bladder. However, this procedure is invasive and 10 - 40% of tumours may remain undetected. A non-invasive examination and a new generation of biomarkers are needed for better monitoring of the disease.

Objective. To assess the usefulness of ultrasound (US) scans for monitoring of structural urinary tract disease by local public health …

Effects Of Urbanization On The Occurrence Of Batrachochytrium Dendrobatidis: Do Urban Environments Provide Refuge From The Amphibian Chytrid Fungus?, Daniel Saenz, Taylor L. Hall, Matthew Kwiatkowski

Faculty Publications

Batrachochytrium dendrobatidis (Bd) is a widespread pathogenic fungus that is known to cause the disease, chytridiomycosis, which can be lethal to many amphibians. We compared occurrence rates on spring peepers (Pseudacris crucifer) in urban and forested breeding sites in eastern Texas, USA. All study sites were at approximately the same latitude and altitude, and samples were collected at the same time of year to isolate differences in Bd infection rates between habitat types. We found significant differences (p<0.001) in the occurrence of Bd between habitats; with dramatically lower rates of occurrence at urban sites (19.5 %), compared to forested sites (62.9 …

The Loss Of Genomic Uracil Homeostasis And Aid-Dependent Accumulation Of Dna Damage In B Cell Lymphomas, Sophia Shalhout

Wayne State University Dissertations

Activation-induced deaminase (AID) is a sequence-selective DNA cytosine deaminase that introduces uracils in immunoglobulin genes. This DNA mutator is required for somatic hypermutation and class switch recombination- processes involved in the affinity maturation and diversification of antibodies. AID, however, can also lead to deleterious mutations and translocations promoting lymphomagenesis. The introduction of uracils throughout the genome of activated B cells and the ability of UNG2 glycosylase to excise these uracils is examined here. This interplay was also studied in cancerous B cells, with different results emerging in transformed cells versus healthy cells. Genomic uracil levels are found to remain at …

Application Of Fluorescence In Situ Hybridization For Visualization And Quantification Of Human Gastrointestinal Microbiota, Alexander M. Gordon

Browse all Theses and Dissertations

The microbiota of the human gastrointestinal tract is the focus of current research due to their role in human health and disease. Modern methods characterize the communities of gut microbiota through the use of culture independent techniques. Technologies such as microarrays and next generation sequencing (NGS) determine microbial profiles by analyzing the pool of 16S ribosomal small subunit RNA genes in the community. These techniques operate through the measurement of genomic content rather than through direct analysis of cells. This approach predisposes the methods to discrepancies and bias. In contrast, the use of fluorescence in situ hybridization (FISH) to analyze …

Antibodies To Pseudogymnoascus Destructans Are Not Sufficient For Protection Against White-Nose Syndrome, Joseph S. Johnson, Deeann M. Reeder, Thomas M. Lilley, Ken Field

Faculty Journal Articles

White-nose syndrome (WNS) is a fungal disease caused by Pseudogymnoascus destructans (Pd) that affects bats during hibernation. Although millions of bats have died from WNS in North America, mass mortality has not been observed among European bats infected by the fungus, leading to the suggestion that bats in Europe are immune. We tested the hypothesis that an antibody-mediated immune response can provide protection against WNS by quantifying antibod- ies reactive to Pd in blood samples from seven species of free-ranging bats in North America and two free-ranging species in Europe. We also quantified antibodies in blood samples from little brown …

Compatibility Factors Of Fascioloides Magna Miracidia And Four Sympatric Snail Species: Miracidial Behavior And Snail Response, Bryan Rolfsen

Masters Theses

Miracidia exhibit observable host-finding behaviors, and their sympatric snails have attributes that either permit or prohibit infection. This study was designed to assess the factors involved in intermediate host finding and host-parasite compatibility in the deer liver fluke (Fascioloides magna). The main aim was to determine the extent to which the parasite and/or the intermediate host are involved in host-parasite compatibility. A secondary goal was to determine what factors may lead to miracidial transformation. The study used a panel of four sympatric snails (Lymnaea caperata, Lymnaea palustris, Lymnaea exilis, and Physa sp.) that display …

Radiation-Induced Esophagitis Is Mitigated By Soy Isoflavones, Matthew Donovan Fountain

Wayne State University Theses

Lung cancer patients receiving radiotherapy present with acute and chronic esophagitis, resulting in pain and difficulties swallowing. These effects are due to radiation injury to the normal tissues in the esophagus. Our previous studies in pre-clinical models of lung cancer and naïve mice have shown that soy isoflavones alleviates radiation-induced toxicity to normal lung, including a decrease in pneumonitis and fibrosis. In this study, we have investigated whether radiation-induced esophagitis can be reduced by soy isoflavones. C57BL/6 mice were treated with 10 Gy or 25 Gy for thoracic irradiation and soy isoflavones given daily at 1mg/mouse up to 16 weeks. …

Francisella Tularensis Catalase Restricts Immune Function By Impairing Trpm2 Channel Activity, Nicole Lynn Flaherty

Legacy Theses & Dissertations (2009 - 2024)

As an innate defense mechanism, macrophages produce reactive species that weaken pathogens and serve as secondary messengers to modify signaling responses involved in immune function. The gram-negative bacterium F. tularensis utilizes its antioxidant armature to limit the host immune response but the mechanism behind this suppression has not been defined. Here we establish that F. tularensis limits Ca2+ entry thereby limiting actin reorganization and IL-6 production in a redox-dependent fashion. Wild-type (LVS) or catalase deficient F. tularensis (∆katG) show distinct profiles in their H2O2 scavenging capacity, 1 pM/sec and 0.015 pM/sec, respectively. Murine alveolar macrophages infected with ∆katG display distinct …

Role Of Antibody Isotypes In Providing Passive Protection Against Ricin Toxin, Ipneet Kaur Dhaliwal

Legacy Theses & Dissertations (2009 - 2024)

Ricin toxin is a glycoprotein produced by the castor bean plant, Ricinus communis. Ricin is an extraordinarily potent inducer of cell death and inflammation, especially following inhalation. The toxin’s enzymatic subunit (RTA) is transported via retrograde transport into the cytoplasm of mammalian cells by the toxin’s B subunit (RTB). Once in the cytoplasm, RTA inactivates ribosomes through cleavage of ribosomal RNA. In this study, I characterized a ricin-specific monoclonal IgA antibody (mAb) known as 23D7. I confirmed that 23D7 reacts with RTA and is effective at neutralizing ricin in a Vero cell cytotoxicity assay in vitro. To localize the epitope …

Curatorial Implications Of Ophyra Capensis (Order Diptera, Family Muscidae) Puparia Recovered From The Body Of The Blessed Antonio Patrizi, Monticiano, Italy (Middle Ages), Johnica J. Morrow, Diesel A. Baldwin, Leon G. Higley, Dario Piombino-Mascali, Karl J. Reinhard

Karl Reinhard Publications

The discovery of dipteran remains on mummified individuals can lead to either cause for curatorial concern or to a better understanding of the individual’s post-mortem environment. The present study analyzed insect remains associated with the body of a unique medieval mummy of religious significance, that of the Blessed Antonio Patrizi da Monticiano. A total of 79 puparia were examined and all were identified as Ophyra capensis (Diptera: Muscidae). Additionally, a desiccated moth (Lepidoptera: Tineidae) was encountered. Puparia of O. capensis would be associated with normal decomposition shortly after the death of the mummified individual, and not an infestation beginning during …
