A Tail Of Two Phages: Genomic And Functional Analysis Of Listeria Monocytogenes Phages Vb_Lmos_188 And Vb_Lmos_293 Reveal The Receptor-Binding Proteins Involved In Host Specificity, Aidan Casey, Kieran Jordan, Horst Neve, Aidan Coffey, Olivia Mcauliffe

Department of Biological Sciences Publications

The physical characteristics of bacteriophages establish them as viable candidates for downstream development of pathogen detection assays and biocontrol measures. To utilize phages for such purposes, a detailed knowledge of their host interaction mechanisms is a prerequisite. There is currently a wealth of knowledge available concerning Gram-negative phage-host interaction, but little by comparison for Gram-positive phages and Listeria phages in particular. In this research, the lytic spectrum of two recently isolated Listeria monocytogenes phages (vB_LmoS_188 and vB_LmoS_293) was determined, and the genomic basis for their observed serotype 4b/4e host-specificity was investigated using comparative genomics. The late tail genes of these …

Exposure Monitoring In Developing Countries, Luis Collado

Graduate Theses & Non-Theses

Formaldehyde is widely used in the healthcare industry. Formaldehyde is used as a disinfectant and sterilant. In addition, formaldehyde/formalin is used as fixative/ preservative of anatomical specimens in pathology departments. Individuals may experience adverse effects following short term exposure above 0.1ppm. Following a laboratory study in the early 1980s, the U.S. Environmental Protection Agency (EPA) classified formaldehyde as a human carcinogen in 1987.

Although the healthcare industry in the United States made major advancement in the safe use of formaldehyde/formalin since the implementation of the Occupational Health and Safety Administration (OSHA) Formaldehyde standard, other developing countries are still struggling with …

Bleaching, Disease, And Colonization: The Ecology Of Coral Health In Southeastern Nosy Be, Madagascar, Luella Allen-Waller

Journal of Environmental and Resource Economics at Colby

Many studies have been conducted analyzing the economic impact of golf courses on the local communities. These studies examine economic impacts of tournaments, endorsements, and vacation expenses of the major golf courses in the United States. However, there is little research conducted on the environmental impact of Golf courses, specifically in Maine. This paper performs a hedonic pricing analysis using housing prices in proximity to golf courses and compares it to the valuation of various land types in Maine. Housing prices were collected in the towns of Auburn, and North Yarmouth both near and distant from the local golf course. …

Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson

Journal of Environmental and Resource Economics at Colby

The Cafe Standards were introduced in 1975 following the Oil Embargo. The goals of this program were simple. To reduce co2 emissions in vehicles by increasing a mandatory average mpg level for car manufacturers in the United States. Recently, in 2012, the Obama Administration set new Cafe Standard requirements for car manufacturers. By 2025, all new cars on the road in the United States must average 54.5 miles per gallon, which would double the current 27 mpg average in place right now. While the intentions of this policy are to reduce co2 emissions while at the same time increasing savings …

The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, Dan Hyszczak

Journal of Environmental and Resource Economics at Colby

Millions of people play golf every year, and in 2011 Golf Courses gained $22 billion dollars in revenue. This statistic combined with golf’s inherent place in the natural environment lead to questions of value and development for golf course owners. In 1991, The Audubon Society created their Cooperative Sanctuary Program for Golf Courses (ACSP) to promote environmentally sustainable practices for golf courses and to recognize the courses that are the most environmentally in both the United States and around the world.

This paper builds off of prior research that connects golf course beauty with revenue by examining the effects of …

Preferences For Coral Reef And Fishery Management In Okinawa, Japan, Nils Carlson

Journal of Environmental and Resource Economics at Colby

This study is an example of how a nonmarket valuation method – a choice experiment – can be used to influence and guide ecosystem conservation efforts. Using a choice experiment survey, this study estimates the willingness to pay (WTP) for certain hypothetical attributes of a restored and conserved coral reef in Okinawa, Japan. I find that an increase in the amount of fish available to catch in ten years as well as an increase in the extent and health of the coral reefs and the number of marine biodiversity found in the Okinawan waters after ten-years, both positively affect respondent’s …

An Exploratory Statistical Analysis of the External and Internal Effects of Art Museums in the United States

The Effects Of Land Conservation On Productivity, Robert Mccormick, Carolyn Fuwa

Journal of Environmental and Resource Economics at Colby

In this research the relationship between productivity of land conservation is analyzed using panel data of the GDP and acres conserved of all 50 U.S. states from 1998-2005. Two main theories of the conservation productivity relationship exist. The first maintains that conservation impedes productivity because it does not allow land cultivation. Conversely, the second theory maintains that land conservation has a positive effect on GDP due to the recreation and tourism it creates. Through the use of fixed effects and random effects regressions, the amount of land conserved per state is not a significant predictor of state GDP The GDP …

A Survey On Climate Change: How Beliefs Shape Responsibility, Connor P. Clancy, Sarah Beth Solomon

Journal of Environmental and Resource Economics at Colby

This paper examines the lack of awareness and feelings of personal responsibility for climate change. Previous literature suggests that while part of the United States population may be aware of climate change, they do not feel personally responsible for causing it despite feeling climate change’s effects just like everyone else. Furthermore, studies suggest that individuals also do not believe climate change will affect them now, but rather it is an issue for future generations. Using a survey, we examine which demographics and personal factors are most important in eliciting awareness for climate change, and furthermore, personal responsibility for its effects. …

An Investigation Of The Effect Of Malathion On Adaptive Plasticity Of Pseudacris Sierra, Michael Jonathan Maples

Master's Theses

This thesis is composed of two chapters. Chapter one reviews what is known about adaptive plasticity in response to predators, describes the physiological systems involved in such plasticity, and outlines the evolutionary consequences of adaptive plasticity. Chapter two describes a scientific experiment that investigates how malathion may impact adaptive plasticity in the Sierran Treefrog, Pseudacris sierra. Anuran tadpoles suffer high mortality rates due to predation. In response to strong selective forces relating to these high predation rates, tadpoles evolved the ability to adaptively respond to predators through morphological and behavioral plasticity. The morphological and behavioral responses are varied and depend …

Cold Plasma Treatment Of Biodegradable Films And Smart Packaging, Shashi Pankaj

Doctoral

Cold plasma is an emerging technology offering many potential applications for food packaging. While it was originally developed to increase the surface energy of polymers, enhancing their adhesion and printability, it has recently emerged as a powerful tool for surface sterilisation of both food and food packaging materials. The food packaging industry is still dominated by petroleum derived polymers but in the past few decades there has been significant interest in the development of environment friendly, biodegradable green polymers. In this study, the interaction and effects of cold plasma with biopolymer based packaging materials (polylactic acid, zein, sodium caseinate, starch, …

Palencar, Kyle J. Gellatly, Kyong-Sup Yoon, Kosta Y. Mumcuoglu, Uri Shalom, J Marshall Clark

SIUE Faculty Research, Scholarship, and Creative Activity

Human bed bug infestations have dramatically increased worldwide since the mid-1990s. A similar phenomenon was also observed in Israel since 2005, when infestations were reported from all over the country. Two single nucleotide polymorphisms (V419L and L925I) in the bed bug voltage sensitive sodium channel confer kdr-type resistance to pyrethroids. Using quantitative sequencing (QS), the resistance allele frequencies of Israeli bed bug populations from across the country were determined. Genomic DNA was extracted from samples of 12 populations of bed bugs collected from Israel and DNA fragments containing the V419L or L925I and I936F mutations sites were PCR amplified. The …

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 …

When Nanoparticles Meet Biofilms—Interactions Guiding The Environmental Fate And Accumulation Of Nanoparticles, Kaoru Ikuma, Alan W. Decho, Boris T. Lau

Faculty Publications

Bacteria are essential components of all natural and many engineered systems. The most active fractions of bacteria are now recognized to occur as biofilms, where cells are attached and surrounded by a secreted matrix of “sticky” extracellular polymeric substances. Recent investigations have established that significant accumulation of nanoparticles (NPs) occurs in aquatic biofilms. These studies point to the emerging roles of biofilms for influencing partitioning and possibly transformations of NPs in both natural and engineered systems. While attached biofilms are efficient “sponges” for NPs, efforts to elucidate the fundamental mechanisms guiding interactions between NPs and biofilms have just begun. In …

Community Health Faculty Publications and Presentations

Background: Many environmental factors have been independently associated with preterm birth (PTB). However, exposure is not isolated to a single environmental factor, but rather to many positive and negative factors that co-occur. The environmental quality index (EQI), a measure of cumulative environmental exposure across all US counties from 2000—2005, was used to investigate associations between ambient environment and PTB.

Methods: With 2000–2005 birth data from the National Center for Health Statistics for the United States (n = 24,483,348), we estimated the association between increasing quintiles of the EQI and county-level and individual-level PTB; we also considered environmental domain-specific (air, …
