In Vitro And In Vivo Evaluation Of Infestation Deterrents Against Lice, Kyong-Sup Yoon, Jennifer K. Ketzis, Samuel W. Andrewes, Christopher S. Wu, Kris Honraet, Dorien Staljanssens, Bart Rossel, J Marshall Clark

SIUE Faculty Research, Scholarship, and Creative Activity

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated ...


Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf 2015 The University of Western Ontario

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

University of Western Ontario - 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 ...


Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane 2015 DePaul University

Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane

DePaul Discoveries

Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide5,6. It is estimated that roughly 80% of those infected suffer from persistent infection with the virus; this persistence of infection is progressive, and over time can lead to fibrosis, cirrhosis, and hepatocellular carcinoma7. Chronic inflammation and apoptotic deregulation are both hallmarks of chronic HCV infection, and many molecular pathways are initiated in both the innate and adaptive immune responses during infection with this viral pathogen. The aim of this review was to survey some of the major molecular mechanisms responsible for the induction of chronic ...

Lyme Disease In The Northeast: Altered Ecosystems And Public Health Impacts, Elisa L. Russo 2015 Fordham University

Lyme Disease In The Northeast: Altered Ecosystems And Public Health Impacts, Elisa L. Russo

Student Theses 2015-Present

Lyme disease has spread rapidly throughout the United States since its original discovery in 1975. An increasing threat to public health, this common vector-borne disease is transferred to a human after receiving a bite from an infected blacklegged tick (Ixodes scapularis). Humans have contributed to the massive influx of tick populations and Lyme disease cases through the introduction of invasive flora and fauna, overhunting of apex predators, and altering areas of land for urbanization. Quantitative data from the CDC and USDA on Lyme disease cases and white-tailed deer populations in the United States demonstrates the impact of human disruption of ...

The immune system can recognize virtually any antigen, yet T cell responses against several pathogens, including Mycobacterium tuberculosis, are restricted to a limited number of immunodominant epitopes. The host factors that affect immunodominance are incompletely understood. Whether immunodominant epitopes elicit protective CD8+ T cell responses or instead act as decoys to subvert immunity and allow pathogens to establish chronic infection is unknown. Here we show that anatomically distinct human granulomas contain clonally expanded CD8+ T cells with overlapping T cell receptor (TCR) repertoires. Similarly, the murine CD8+ T cell response against M. tuberculosis is dominated by TB10.44-11-specific T cells ...


Adapting The Standard Sir Disease Model In Order To Track And Predict The Spreading Of The Ebola Virus Using Twitter Data, Armin Smailhodzic 2015 Western Kentucky University

Adapting The Standard Sir Disease Model In Order To Track And Predict The Spreading Of The Ebola Virus Using Twitter Data, Armin Smailhodzic

Masters Theses & Specialist Projects

A method has been developed to track infectious diseases by using data mining of active Twitter accounts and its efficacy was demonstrated during the West African Ebola outbreak of 2014. Using a meme based n-gram semantic usage model to search the Twitter database for indications of illness, flight and death from the spread of Ebola in Africa, principally from Guinea, Sierra Leone and Liberia. Memes of interest relate disease to location and severity and are coupled to the density of Tweets and re-Tweets. The meme spreads through the community of social users in a fashion similar to nonlinear wave propagation- ...


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 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 ...

Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, Prageeth Wijemanne, Jun Xing, Emil M. Berberov, David B. Marx, David H. Francis, Rodney A. Moxley 2015 University of Nebraska-Lincoln

Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, Prageeth Wijemanne, Jun Xing, Emil M. Berberov, David B. Marx, David H. Francis, Rodney A. Moxley

Papers in Veterinary and Biomedical Science

Heat-labile enterotoxin (LT) is an important virulence factor secreted by some strains of enterotoxigenic Escherichia coli (ETEC). The prototypic human-origin strain H10407 secretes LT via a type II secretion system(T2SS). We sought to determine the relationship between the capacity to secrete LT and virulence in porcine-origin wild type (WT) ETEC strains. Sixteen WT ETEC strains isolated from cases of severe diarrheal disease were analyzed by GM1ganglioside enzyme- linked immunosorbent assay tomeasure LT concentrations in culture supernatants. All strains had detectable LT in supernatants by 2 h of culture and 1 strain, which was particularly virulent in gnotobiotic piglets (3030-2 ...

Plasmacytoid dendritic cells (pDCs) were initially considered as critical for innate immunity to viruses. However, our group has shown that pDCs bind to and inhibit the growth of Aspergillus fumigatus hyphae and that depletion of pDCs renders mice hypersusceptible to experimental aspergillosis. In this study, we examined pDC receptors contributing to hyphal recognition and downstream events in pDCs stimulated by A. fumigatus hyphae. Our data show that Dectin-2, but not Dectin-1, participates in A. fumigatus hyphal recognition, TNF-alpha and IFN-alpha release, and antifungal activity. Moreover, Dectin-2 acts in cooperation with the FcRgamma chain to trigger signaling responses. In addition, using ...


Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown 2015 Department of Biological Sciences, University of Tulsa

Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown

Papers in Natural Resources

When blood-feeding parasites increase seasonally, their deleterious effects may prevent some host species, especially those living in large groups where parasites are numerous, from reproducing later in the summer. Yet the role of parasites in regulating the length of a host’s breeding season—and thus the host’s opportunity for multiple brooding—has not been systematically investigated. The highly colonial cliff swallow (Petrochelidon pyrrhonota), a temperate-latitude migratory songbird in the western Great Plains, USA, typically has a relatively short (eight to nine week) breeding season, with birds rarely nesting late in the summer. Colonies at which ectoparasitic swallow bugs ...


Time-To-Infection By Plasmodium Falciparum Is Largely Determined By Random Factors, Mykola Pinkevych, Kiprotich Chelimo, John Vulule, James W. Kazura, Ann M. Moormann, Miles P. Davenport 2015 University of New South Wales

Time-To-Infection By Plasmodium Falciparum Is Largely Determined By Random Factors, Mykola Pinkevych, Kiprotich Chelimo, John Vulule, James W. Kazura, Ann M. Moormann, Miles P. Davenport

University of Massachusetts Medical School Faculty Publications

BACKGROUND: The identification of protective immune responses to P. falciparum infection is an important goal for the development of a vaccine for malaria. This requires the identification of susceptible and resistant individuals, so that their immune responses may be studied. Time-to-infection studies are one method for identifying putative susceptible individuals (infected early) versus resistant individuals (infected late). However, the timing of infection is dependent on random factors, such as whether the subject was bitten by an infected mosquito, as well as individual factors, such as their level of immunity. It is important to understand how much of the observed variation ...

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a prototypical neglected tropical disease. Specific immunity promotes acute phase survival. Nevertheless, one-third of CD patients develop chronic chagasic cardiomyopathy (CCC) associated with parasite persistence and immunological unbalance. Currently, the therapeutic management of patients only mitigates CCC symptoms. Therefore, a vaccine arises as an alternative to stimulate protective immunity and thereby prevent, delay progression and even reverse CCC. We examined this hypothesis by vaccinating mice with replication-defective human Type 5 recombinant adenoviruses (rAd) carrying sequences of amastigote surface protein-2 (rAdASP2) and trans-sialidase (rAdTS) T. cruzi antigens. For prophylactic vaccination, naive ...

Prehistoric Earth Oven Facilities And The Pathoecology Of Chagas Disease In The Lower Pecos Canyonlands, Karl Reinhard, Adauto Araujo

Papers in Natural Resources

Understanding the endemic region of a disease is part of developing a concept of the disease’s natural history and its threat to human health in both ancient and modern times. Chagas disease is caused by the parasite Trypanosoma cruzi and has recently been identified as an emergent disease in North America. Ancient endemicity and reemergence has been demonstrated by an examination of a mummy found on the border between Coahuila, Mexico and Texas, USA. This mummified man, who died over 1000 years ago, exhibits the gross pathology of megacolon, which is consistent with Chagas disease. We are now exploring ...
