Elucidation Of Novel And Established Campylobacter Species With Clinical And Agricultural Significance Through Phenotypic, Genotypic, And Taxonomic Investigation, Caoimhe Lynch

Theses

Campylobacter spp. are well-established human, veterinary and economic pathogens, with a broad host range spanning from terrestrial and marine mammalian, avian and reptilian hosts. The scope of the study includes novel and notorious species within the genus, with reference to zoonotic agents Campylobacter jejuni and Campylobacter coli - the leading cause of human bacterial gastroenteritis in the EU and Ireland, Campylobacter fetus that represents the most common campylobacter causing bacteraemia and two novel species isolated from pigs not described in the literature previously. C. jejuni and C. coli isolates (n = 350) recovered from broiler caecal and neck skin samples, …

Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz

Theses

Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.

The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …

Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell

Theses

While the Irish agricultural sector accounts for just 6% of the working population of Ireland, it consistently has the highest proportion of fatal incidents of any sector - generally ranging from between 35% and 45% of all workplace fatalities in any given year (Health and Safety Authority, 2015). This was again evident in 2014 where 55% (30 of the 56) of the fatal workplace incidents were in the agricultural sector (Health and Safety Authority, 2015). Agriculture has an ageing workforce with the average age of an Irish farmer now standing at fifty-seven and farmers are eight times more likely to …

An Analysis Of The Physiological And Psychological Wellbeing Of Irish Naval Service Personnel, Cliodhna Sargent

Theses

Whilst all military cohorts have been seen to experience both physiological and psychological stressors during occupational duties, the naval service experience different stressors due the prolonged periods of time spent at sea. Research has analysed some of these stressors however many them have focused on how individuals are affected because of time spent in combat zones. The Irish Naval Service (INS) is an organisation under the Irish Defence Forces organisation and as such many of its physiological and psychological assessment procedures have come from the Defenee Forces. Very limited researeh has been carried out in relation to the INS as …

Participation And Determinants Of Physical Activity Amongst Irish 3rd Level Students., Jonathan Lerner

Theses

Currently, there is a dearth of research investigating physical activity patterns among Irish third level young adults (17-22 year olds). Both national and international research report that levels of physical activity decline in adolescence, this trend being most pronounced among females. Various biological, psychological, social, and environmental determinants have been found to influence physical activity; however, specific factors associated with the decline in activity during adolescence remain largely unknown. This research study examines participation and determinants of physical activity among Irish third level students.

A “National questionnaire” was administered to a sample of 532 students from Health Education Authority (HEA) …

Molecular Epidemiology Of Antibiotic Resistant Salmonella Enterica Strains From Different Animal And Human Sources In Ireland, David George Lee

Theses

In this study, 176 isolates of Salmonella were collected from different laboratories in Ireland. All isolates were confirmed to be of the genus Salmonella by performing bacteriological and biochemical tests. Briefly, all isolates were cultured onto XLD agar after which pure cultures were verified and stocked at this institute. Definitive identification was carried out using the API 20-E system and a separate urease test was also performed on all isolates. After confirmation of the genus, all isolates were prepared for antibiotic susceptibility testing and r-types were determined using sixteen antibiotics. Depending on the antibiotic resistance profiles, isolates were selected for …
