The Role Of Accessory Domain In Cpsa Function And Capsule Production In Group B Streptococcus, Gina Difederico May 2021

The Role Of Accessory Domain In Cpsa Function And Capsule Production In Group B Streptococcus, Gina Difederico

Honors College

Group B Streptococcus (GBS) can be found in the vaginal and genitourinary tract of females, as well as the genitourinary tract of males, where it behaves as a commensal organism. However, as an opportunistic pathogen, GBS has the capability to infect the immunocompromised, making it a major threat to neonates and fetuses. The pathogen can be passed from mother to baby either in utero or during birth. The capsule, which is a polysaccharide coating on the outside of the cell, is considered the most important virulence factor in GBS.Expression of capsule plays a role in evasion of the host immune …


Ecological Niche Modeling Of Lyme Disease Risk In Maine Based On Human Case Data, Elizabeth Dee May 2021

Ecological Niche Modeling Of Lyme Disease Risk In Maine Based On Human Case Data, Elizabeth Dee

Honors College

Ixodes scapularis, the blacklegged tick,is the primary vector for the Lyme disease-causing bacteria Borrelia burgdorferi in the United States.Lyme disease poses a significant concern to the state of Maine, as both the number and geographic distribution of cases across the state have been steadily increasing over the past two decades. In 2001, there were 108 confirmed or probable cases of Lyme disease in Maine compared to 1404 cases in 2018. Using tick-borne disease human case data from the Maine CDC andArcGIS software, I created three Lyme disease maps for the years 2001, 2009, and 2017. These maps show the number …


The Relationship Between Kidney Function And Cognitive Function In Type Ii Diabetes, Erika Pacheco May 2021

The Relationship Between Kidney Function And Cognitive Function In Type Ii Diabetes, Erika Pacheco

Honors College

Individuals who are diagnosed with Type II Diabetes Mellitus (T2DM) have shown decline in proper kidney function, ultimately leading to a form of chronic kidney disease (CKD) in about one-third of T2DM cases. Even though these are alarming rates of both diseases, these conditions are rarely studied concurrently. The general focus for this research is to identify whether or not kidney function in individuals with T2DM relates to their cognitive function. Specifically, is albuminuria in individuals with T2DM a risk for poorer cognitive performance? Maine Syracuse Longitudinal Study (MSLS) data for the 121 participants with T2DM was analyzed through correlational …


Identifying Risk Factors Of Anaplasma Infection In Plains Zebra Of Etosha National Park, Namibia, Madison Stahle May 2021

Identifying Risk Factors Of Anaplasma Infection In Plains Zebra Of Etosha National Park, Namibia, Madison Stahle

Honors College

Anaplasmosis is a tick-borne illness that is caused by bacteria from the genus Anaplasma which infect the blood cells of their hosts. Anaplasmosis can affect the health and life expectancy of zebra, however, little is known about what makes drives the variability in infection within this species. The purpose of this study is to (1) determine the prevalence, and (2) identify risk factors for Anaplasma infections in plains zebra (Equus quagga) from the Etosha National Park, Namibia, including whether Anaplasma infections correlate with other parasite infections (ectoparasites and gastrointestinal parasites).Other possible risk factors for Anaplasma infection that are …
