Release Of Vocs, Gasses, And Bacteria From Contaminated Landings And Creeks Of Ogeechee River Basin, Victoria A. Clower, Melanie Sparrow, Atin Adhikari

Department of Biostatistics, Epidemiology, and Environmental Health Sciences Faculty Publications

River landings are common public grounds, visited by many people every day. The aftermath of visiting these places may be unsettling since much trash is left behind and scattered throughout. The litter collects and with each rain or high wind, it has a better chance of ending up in our streams, rivers, creeks, and eventually our oceans. The main purpose of this study was to measure both air and water quality throughout the Ogeechee River basin in South Georgia to determine how each was impacted by trash. Ammonia, methane, and volatile organic compounds (VOCs) along with temperature and humidity were …

Although microbial populations in the gut microbiome are associated with COVID-19 severity, a causal impact on patient health has not been established. Here we provide evidence that gut microbiome dysbiosis is associated with translocation of bacteria into the blood during COVID-19, causing life-threatening secondary infections. We first demonstrate SARS-CoV-2 infection induces gut microbiome dysbiosis in mice, which correlated with alterations to Paneth cells and goblet cells, and markers of barrier permeability. Samples collected from 96 COVID-19 patients at two different clinical sites also revealed substantial gut microbiome dysbiosis, including blooms of opportunistic pathogenic bacterial genera known to include antimicrobial-resistant species. …

Trends In Legionnaires' Disease-Associated Hospitalizations, United States, 2006-2010, Gayathri Mudali, Paul E. Kilgore, Abdulbaset Salim, Shawn P. Mcelmurry, Marcus Zervos

Department of Pharmacy Practice

Background: Legionella pneumophila is a waterborne cause of both healthcare-associated and community-acquired pneumonia. Legionella pneumophila serogroup 1 is responsible for 80% of infections. There is currently limited published disease burden data on Legionnaires' disease-associated hospitalization in the United States.

Methods: In this study, we estimated the annual incidence of Legionnaires' disease-associated hospitalizations in United States and identified demographic, temporal, and regional characteristics of individuals hospitalized for Legionnaires' disease. A retrospective study was conducted using the National Hospital Discharge Survey (NHDS) data from 2006 to 2010. The NHDS is a nationally representative US survey, which includes estimates of inpatient stays in …

Consequences Of Pathogen Lists: Why Some Diseases May Continue To Plague Us, David Brett-Major, Trina Racine, Gary P. Kobinger

Journal Articles: Epidemiology

The current strategy used by many funding agencies for determining how money is spent on research to help prevent infectious disease outbreaks is based on pathogen-specific priority lists. Listing disease threats provides focus for business and research planning conducive to specific goals of developing a drug, or a vaccine, or other particular product. But, this singular type of focus has consequences. This perspective explores the consequences of lists, and describes how parallel programming independent of disease lists that address what we need to do to prevent and mitigate emerging disease risks may provide benefits out of reach of a singular …

The Effect Of Agricultural Exposures And Genetics On Respiratory Phenotypes, Lisa W. Boyd

Theses & Dissertations

Agricultural workers are at risk for respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and chronic bronchitis, due to exposures and inflammatory agents found in their work environment. While previous studies have been conducted to examine agricultural effects of chronic respiratory diseases more closely, there are still several significant gaps in the existing literature.

This dissertation explores the relationship between agricultural exposures and respiratory diseases. Utilizing two populations, the Keokuk Country Rural Health Study and the AgLung Study, this research: 1) used principal factor analysis (PFA) to distill exposure data into essential variables characterizing long-term agricultural exposures in order …

A Comparative Study Of Indicator Bacteria Present In Ice And Soda From Las Vegas Food Establishments, Kimberly Jo Hertin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Microbial analysis has long been used as an indicator of water quality. Since the passing of the Safe Drinking Water Act in 1974, microbial standards have been strictly set by the Environmental Protection Agency (EPA) to ensure that the public health is protected from bacterial pathogens. The bacteriological quality of water generally deteriorates as it travels from water treatment facilities through the main distribution system and into private plumbing and distribution systems. For example, Heterotrophic Plate Count (HPC) values typically increase once the water has entered plumbing devices such as beverage vending machines. Upon reaching a private facility, the opportunity …
