Infection-Associated Mycobacterium Fortuitum Infection, Dennis T. Huang, Larry Lutwick Jan 2017

Infection-Associated Mycobacterium Fortuitum Infection, Dennis T. Huang, Larry Lutwick

Research Day

Introduction: Mycobacterial species are unusual causes of skin and soft tissue infections and can be difficult to diagnose in the absence of consideration as they often require specific culture media and longer incubation times. We report a Mycobacterium fortuitum subcutaneous abscess in a diabetic related to medication injection that was initially diagnosed without specialized media or prolonged incubation times. Case Report: A 48 year old diabetic female developed a progressive subcutaneous swelling in the tissues of the right lower abdominal wall where she had been injecting liraglutide. Because of continued enlargement "to almost egg size" with pain, she was empirically …

Pathology, East Africa

Hospital-acquired infections (HAIs) are a major concern to healthcare systems around the world. They are associated with significant morbidity and mortality, in addition to increased hospitalization costs. Recent outbreaks, including those caused by the Middle East respiratory syndrome coronavirus and Ebola virus, have highlighted the importance of infection control. Moreover, HAIs, especially those caused by multidrug-resistant Gram-negative rods, have become a top global priority. Although adequate approaches and guidelines have been in existence for many years and have often proven effective in some countries, the implementation of such approaches in low- and middle-income countries (LMICs) is often restricted due to …

A previous report indicated that prototype chlorovirus PBCV-1 replicated in two Chlorella variabilis algal strains, NC64A and Syngen 2-3, that are ex-endosymbionts isolated from the protozoan Paramecium bursaria. Surprisingly, plaque-forming viruses on Syngen 2-3 lawns were often higher than on NC64A lawns from indigenous water samples. These differences led to the discovery of viruses that exclusively replicate in Syngen 2-3 cells, named Only Syngen (OSy) viruses. OSy-NE5, the prototype virus for the proposed new species, had a linear dsDNA genome of 327 kb with 44-nucleotide-long, incompletely base-paired, covalently closed hairpin ends. Each hairpin structure was followed by an identical …

Human Antibody Responses To Pneumococcal Vaccination In Aging Hiv-Positive Individuals, Megan Bickford Jan 2017

Human Antibody Responses To Pneumococcal Vaccination In Aging Hiv-Positive Individuals, Megan Bickford

MUSC Theses and Dissertations

Introduction: Streptococcus pneumoniae is a major cause of morbidity and mortality in HIV-positive individuals. Despite the widespread use of anti-retroviral medications, the incidence of pneumococcal disease is 20-40 fold higher in the HIV+ population compared to HIV- persons. Consequently, pneumococcal vaccination is recommended for all HIV+ individuals. In 2012 the FDA changed vaccine recommendation from a single vaccination with the 23-valent pneumococcal polysaccharide vaccine (PPV23) to a dual vaccination with 13-valent protein conjugate vaccine (PCV13) followed by PPV23. Studies demonstrating superiority of the PCV13/PPV23 regimen compared to PPV23 alone are limited and controversial. The goal of this study was to …

Viral And Cellular Micrornas In Regulation Of Ebv Latency And Oncogenesis, Ling Wang, Shunbin Ning Jan 2017

Viral And Cellular Micrornas In Regulation Of Ebv Latency And Oncogenesis, Ling Wang, Shunbin Ning

ETSU Faculty Works

Epstein-Barr virus (EBV), an oncogenic virus that ubiquitously establishes life-long persistence in humans, encodes viral miRNAs in two clusters, BHRF1 and BART. EBV also regulates expression of a large pool of cellular miRNAs, including miR-155, miR-146a, miR-21, miR-29, and miR-34a. These miRNAs targets both viral and cellular genes involved in the entire viral lifetime from lytic infection to oncogenesis, including viral replication, immune responses, cell cycle regulation, apoptosis, and cell proliferation, and are indispensable for persistent infection, latency establishment and maintenance, and cancer development. Among them, circulating miRNAs and unique miRNA profiles are promising diagnosis and prognosis biomarkers alone or …

Retention In Continuous Care And Sustained Viral Suppression: Examining The Association Among Individuals Living With Hiv, Timothy N. Crawford, Alice C. Thornton

Internal Medicine Faculty Publications

Objectives: To examine the relationship between retention in continuous care and sustained viral suppression.

Methods: The authors retrospectively followed 653 persons who were virally suppressed and seeking care at an infectious disease clinic in Kentucky for an average of 6 years to determine the rates of retention in medical care (≥2 visits separated by ≥3 months within a 12-month period) and sustained viral suppression (<400 copies/mL). A generalized linear mixed model was used to determine an association between retention and suppression over time.

Results: Approximately 61% of the study population were retained in continuous care and 75% had sustained viral suppression for all patient-years. Persons retained in care were 3 times the odds of sustaining viral suppression over …

Practical Guide And Atlas For The Diagnosis Of Fungal Infections, Afia Zafar, Kauser Jabeen, Joveria Farooqi

Books

Laboratory diagnosis of fungal infections remains challenging in South East Asia as it is a neglected field in most diagnostic centres in the developing world. Initial microscopic examination of clinical specimens for the presence of fungal elements followed by growth and eventual identification of isolates up to genus and species levels are very basic and important services that must be provided by any clinical microbiology laboratory. These services have considerable impact on selection of appropriate antifungal therapy and ultimate reduction in morbidity and mortality. With the realisation of scarcity of this service and expertise in Pakistan, our group decided to …

Type 2 Immune Responses In The Context Of Helminth Infection, Asthma, Dendritic Cells, And Myeloid Derived Suppressor Cell Function, Sheela Ruby Damle Jan 2017

Type 2 Immune Responses In The Context Of Helminth Infection, Asthma, Dendritic Cells, And Myeloid Derived Suppressor Cell Function, Sheela Ruby Damle

Theses and Dissertations

Type 2 (TH2) immune responses evolved to respond to helminth parasite infections by the production of TH2 cytokines, which stimulate anti-helminth immunity. Macrophage migration inhibitor factor (MIF) is a pleiotropic cytokine, which is produced by many cell types. We demonstrate that mice deficient in MIF have enhanced clearance of a helminth parasite. MIF deficiency in CD4+ T cells was found to be the most important for mediating parasite clearance. We mimicked MIF deficiency by administering an inhibitor of the MIF tautomerase activity, sulforaphane, and this also increased parasite clearance (Section I).

TH2 immune …

Reactivation Of Hiv-1 Proviruses In Immune-Compromised Mice Engrafted With Human Voa-Negative Cd4+ T Cells, Zhe Yuan, Guobin Kang, Wuxun Lu, Qingsheng Li

Nebraska Center for Virology: Faculty Publications

Background: HIV-1 infection remains incurable on antiretroviral therapy (ART) due to virus latency. To date, enhanced co-culture assays, including viral outgrowth assays (VOA), are commonly used to measure HIV-1 latent reservoirs and evaluate latency-reversing agents (LRAs). However, VOA can only reactivate a small fraction of intact proviruses.

Methods: To explore the utility of NOD scid gamma (NSG) mice as an in vivo model to reactivate HIV-1 proviruses from VOA-negative CD4+ T cells, resting CD4+ T cells from an HIV-1 latently infected individual were isolated and the human CD4+ T cells corresponding to VOA-positive and VOA-negative CD4+ T cells were engrafted …
