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, …
Aims: Action Against Infirmity And Malnutrition In Seniors, Maeve Lorraine Mary O'Connell
Aims: Action Against Infirmity And Malnutrition In Seniors, Maeve Lorraine Mary O'Connell
Theses
Aim: The primary aim of this thesis was to investigate the relationship between nutrition and frailty in Irish older adults. The nutritional status, dietary quality and perceived barriers/motivators to nutrition were also examined, and a frailty intervention protocol was designed. Methods: Cross-sectional study in Irish community-dwelling adults aged ≥65 years. Nutritional status, dietary intake, functional mobility and food choice motivators/healthy eating barriers were assessed using the Mini Nutritional Assessment – Short Form (MNA-SF), a food frequency questionnaire (FFQ), the Timed Up and Go (TUG) test and a custom designed 2-item questionnaire, respectively. Frailty was defined as three or more of …
Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell
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 …
Investigation Of The Natural Bacteriocin Nisin And Bioengineered Nisin Derivatives For The Prevention And Control Fo Staphylococcus Biofilms On Medical Device Materials, Leanne Kearney
Theses
Antimicrobial resistance has evolved into being one the major threats facing clinical environments worldwide. It has led to the deerease in effective prevention and treatment of pathogenic bacteria. One such bacterium is Staphylococcus epidermidis. Once considered a relatively harmless and commensal baeterium, it has recently evolved into being one the leading eauses of nosocomial infections. S. epidermidis has proven hamiful due to its ability to fonn detrimental biofilms. Biofilms are structured eonsortia of bacteria embedded in a self-produced polymer matrix that allows adherence to biotic or abiotic surfaces. These biofilms have played a leading role in healthcare-acquired infections with particular …
Extraction And Characterisation Of Essential Oils From Waste Eucalyptus Foliage, Hugh O'Reilly
Extraction And Characterisation Of Essential Oils From Waste Eucalyptus Foliage, Hugh O'Reilly
Theses
Extraction procedures such as steam distillation, solvent and soxhlet extraction have been investigated to determine the most effective method of extracting essential oil from the foliage of a number of species of Eucalyptus cultivated in Co. Kerry. Steam distillation has been found to be the most effective method of extraction. The steam distillation extraction method has been thoroughly studied in order to determine the factors affecting yield and composition of the distillate. Alteration of the distillation time has been found to produce oil high in 1,8-cineole content, a requirement of medicinal quality oil. The choice of individual distillation still used …
The Surveillance And Control Of Foodborne Diseases, Donal J. Daly
The Surveillance And Control Of Foodborne Diseases, Donal J. Daly
Theses
There is great variation in the extent of surveillance of foodbome disease throughout the world. Some countries contribute important epidemiological and microbiological data to the WHO Surveillance Programme for Foodbome Diseases in Europe. While the UK is a major contributor to this programme, data from Eire has been non-existent. Trends in the incidence of foodbome disease in the UK may have particular relevance to Eire given the similarity of culture. Microbiological and epidemiological data in relation to foodbome pathogens, foods most frequently incriminated in outbreaks, places where outbreaks occur, together witli the main contributory factors are discussed. The broader area …
