Characterization Of The Paracoccidioides Hypoxia Response Reveals New Insights Into Pathogenesis Mechanisms Of This Important Human Pathogenic Fungus, Patrícia De Sousa Lima, Dawoon Chung, Alexandre Melo Bailão, Robert A. Cramer, Célia Maria De Almeida Soares
Characterization Of The Paracoccidioides Hypoxia Response Reveals New Insights Into Pathogenesis Mechanisms Of This Important Human Pathogenic Fungus, Patrícia De Sousa Lima, Dawoon Chung, Alexandre Melo Bailão, Robert A. Cramer, Célia Maria De Almeida Soares
Dartmouth Scholarship
Background: Hypoxic microenvironments are generated during fungal infection. It has been described that to survive in the human host, fungi must also tolerate and overcome in vivo microenvironmental stress conditions including low oxygen tension; however nothing is known how Paracoccidioides species respond to hypoxia. The genus Paracoccidioides comprises human thermal dimorphic fungi and are causative agents of paracoccidioidomycosis (PCM), an important mycosis in Latin America.
How Social Determinants Of Health, Health-Seeking Behaviors, And Treatment Adherence Influence And Interact With Endemic Levels Of Pulmonary Tb And Mdr-Tb In Urban Rajasthan, Michelle Kagei
Independent Study Project (ISP) Collection
Tuberculosis, the worlds most deadly infectious disease, remains as one of the major causes of morbidity and mortality in modern-day India. The country has the highest burden of both tuberculosis as well as multidrug-resistant tuberculosis, a more recently emerging menace. This study focuses on the social determinants of health pertaining to tuberculosis, identifying and discussing “at-risk” groups in the population of urban Rajasthan. Jaipur was chosen as the field study location because of the city’s extensive levels of healthcare institutions and facilities. In order to identify common patient demographics as well as issues regarding treatment adherence, medical records and interviews …

Macrolide-resistant Mycoplasma pneumoniae (MRMP) is highly prevalent in Asia and is now being reported from Europe. Few data on MRMP are available in the United States. Using genotypic and phenotypic methods, we detected high-level MRMP in 13.2% of 91 M. pneumoniae–positive specimens from 6 US locations.

The formation and maintenance of granulomas is central to the host response to Mycobacterium tuberculosis (Mtb) infection. It is widely accepted that the lungs of patients with tuberculosis (TB) usually contain multiple infection foci, and that the granulomas evolve and differentiate independently, resulting in considerable heterogeneity. Although gene expression profiles of human blood cells have been proposed as biomarkers of Mtb infection and/or active disease, the immune profiles of discrete lesion types has not been studied extensively. Using histology, immunopathology and genome-wide transcriptome analysis, we explored the immunological profile of human lung TB granulomas. We show that although the different …

Accelerating The Dual Elimination Of Mother‐To‐Child Transmission Of Syphilis And Hiv: Why Now?, James Kiarie, Chandra K. Mishra, Marleen Temmerman, Lori Newman
Obstetrics and Gynaecology, East Africa
Even though the elimination of congenital syphilis has been on the maternal and child health (MCH) agenda for over a decade, elimination has not yet been achieved; what, then, are the factors currently facilitating the elimination of mother-to-child transmission (MTCT) of syphilis?

Cronobacter sakazakii, commonly found in contaminated infant formula and thereby causes infantile bacteremia, is rarely associated with adult bacteremia. We present the tenth case of C. sakazakii bacteremia in adults. The patient is a 76-year-old woman who resides in a skilled nursing facility and presents with risk factors including bullous pemphigoid, Type II diabetes mellitus, hypertension, hyperlipidemia, chronic kidney disease, and anemia. The therapy was started with intravenous ciprofloxacin and vancomycinempirically. After consultation with an Infectious Diseases specialist, ciprofloxacin and vancomycin was replaced with meropenem based on the patient’s extensive bullous lesions, history of ESBL infections, and possible pneumonia. Later, …
Periodontal Disease: Molecular Visualization Through Computer Modeling And 3d Printing, Catherine Chatowsky
Periodontal Disease: Molecular Visualization Through Computer Modeling And 3d Printing, Catherine Chatowsky
Senior Honors Projects
Periodontal disease is a common infection that damages gingival tissue and creates jawbone destruction that can lead to the loosening or loss of teeth. Hundreds of diverse bacterial species reside in the harsh environment of the oral cavity. The creation of plaque and biofilms serve to allow the bacteria to avoid immune-mediated destruction. This project analyzed periodontal disease pathogens using molecular printing 3D visualization. Two bacterial species (T. denticola and P. gingivalis) were chosen from the public resource: Research Collaboratory for Structural Bioinformatics: Protein Data Bank. T. denticola was a bacteria found to have a binding protein (FhbB) …

Background. Techniques to identify AmpC β-lactamases in SPICE organisms are not yet optimized for the clinical laboratory and are not routinely done. Clinicians are often left with an uncertainty on the choice of antibiotic when a SPICE organism is isolated. The purpose of this study is to evaluate the outcomes of carbapenem versus non-carbapenem regimens in treating bacteremia or urinary tract infection (UTI) from a SPICE organism in a “real-world” setting.
Methods. This was a single-center, retrospective, case-cohort study consisting of adult patients who had clinical infection with a SPICE organism isolated from blood or urine cultures. Patients …

Francisella tularensisis a facultative intracellular pathogen, and is the causative agent of a fatal human disease known as tularemia. F. tularensis is classified as a Category A Biothreat agent by the CDC based on its use in bioweapon programs by several countries in the past and its potential to be used as an agent of bioterrorism. No licensed vaccine is currently available for prevention of tularemia. In this study, we used a novel approach for development of a multivalent subunit vaccine against tularemia by using an efficient tobacco mosaic virus (TMV) based delivery platform. The multivalent subunit vaccine was formulated …

The opportunistic pathogen Pseudomonas aeruginosa can infect almost any site in the body but most often targets epithelial cell-lined tissues such as the airways, skin, and the cornea of the eye. A common predisposing factor is cystic fibrosis (CF), caused by defects in the cystic fibrosis transmembrane-conductance regulator (CFTR). Previously, we showed that when P. aeruginosa enters epithelial cells it replicates intracellularly and occupies plasma membrane blebs. This phenotype is dependent on the type 3 secretion system (T3SS) effector ExoS, shown by others to induce host cell apoptosis. Here, we examined mechanisms for P. aeruginosa-induced bleb formation, focusing on its …

Staphylococcus aureus infections are a common cause of disease, particularly in colonized persons. Recently, a series of published articles have reported that community-acquired methicillin-resistant S. aureus (CA-MRSA) strains are evolving and increasingly becoming prevalent in households while health care acquired MRSA (HA-MRSA) is declining in the USA. The changing superbugs have often been used as an example of evolution in action. Although MRSA infections have become increasingly reported in the community, population-based studies of students preparing for the health professions having S. aureus and MRSA colonization are lacking. During the 2014–2015 school year 544 students were tested for MRSA carriage …
