The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
Electronic Theses and Dissertations
Dickeya dianthicola (Samson) causing blackleg and soft rot was first detected in potatoes grown in Maine in 2014. Previous work has suggested that insects, particularly aphids, may be able to vector bacteria in this genus between plants, but no conclusive work has been done to confirm this theory. In order to determine whether insect-mediated transmission is likely to occur in potato fields, two model potato pests common in Maine were used: the Colorado potato beetle (Leptinotarsa decimlineata Say) and the green peach aphids (Myzus persicae Sulzer). Olfactometry and recruitment experiments evaluated if either insect discriminates between infected and …
An Intersectional Feminist Approach To Lyme Disease Epidemiology, Meghan Frisard
An Intersectional Feminist Approach To Lyme Disease Epidemiology, Meghan Frisard
Honors College
Nationally, Maine is the state with the second highest incidence of Lyme disease. While the spread of Lyme disease is generally attributable to ecological factors that affect the life cycle of Lyme-spreading ticks, socioeconomic factors may have substantial impacts on diagnosis and reporting of human cases. Socioeconomic factors could influence one’s ability to see a healthcare provider and ultimately be diagnosed with and treated for Lyme. Additionally, access to and treatment within the healthcare system is often gendered. I hypothesize that certain socioeconomic factors will have a negative correlation with Lyme disease incidence among the general population and among women, …

Mmp13 Inhibition Does Not Rescue Gmppb-Deficient Skeletal Muscle In Zebrafish, Sean Driscoll
Honors College
The dystroglycan protein is one of many that attach skeletal muscle fibers to the basement membrane at the myotendinous junction. In the alpha-subunit of the dystroglycan molecule, there are sugar chains that help with the adhesion of the molecule to the basement membrane. A mutation in any gene that codes for an enzyme that adds these sugar chains can result in a form of congenital muscle disease called secondary dystroglycanopathy. One of the genes that codes for an enzyme that adds sugar chains is GMPPB and a mutation in this gene results in GMPPB-associated dystroglycanopathy. Using zebrafish as a model …
The Most Critical Resource: How Climate Change Fuels The Crisis In Syria And The Implications For The World At Large, Edward Medeiros
The Most Critical Resource: How Climate Change Fuels The Crisis In Syria And The Implications For The World At Large, Edward Medeiros
Honors College
The Syrian crisis, both domestic and international in scope, may well be the defining geopolitical challenge of the generation. Climate change may be the single greatest challenge to face humanity in the entirety of our species’ life history. The dramatic effects of climate change can be seen in the origins of the Syrian crisis when one looks to humanity’s single most critical resource: water. We take the word critical to have two meanings in this context: first, that water is essential to human survival and second that water is a resource in critical condition. Syria’s water crisis pre-dates the civil …

Construction Of A Cpsa Double Mutant To Determine The Function Of The Lyt-R Domain, Klarissa Klier
Honors College
Streptococcus agalactiae, otherwise known as Group B Streptococcus (GBS), is a zoonotic, Gram-positive, commensal and invasive bacteria which is the leading cause of neonatal bacterial infections. These bacterial infections include sepsis, meningitis, pneumonia, and bacteremia. In neonates, GBS is most commonly transferred to the child in utero or during birth when the child aspirates amniotic or vaginal fluids. GBS can also infect the child through the bloodstream while in utero, causing premature births or still births. Children who survive the initial infection develop severe morbidities which include mental retardation, cerebral palsy, and seizures. GBS can also affect immunocompromised adults, …
