Pipecolic Acid And Novel Insights Into Cerebral Malaria, Akua E. Mensah
Pipecolic Acid And Novel Insights Into Cerebral Malaria, Akua E. Mensah
Theses
Cerebral malaria (CM), a severe manifestation of Plasmodium infection, prompts our investigation into the nuanced role of pipecolic acid in its pathophysiology. To unravel the molecular intricacies, we conducted in vitro lysine labeling techniques of mice infected with P. berghei ANKA parasites, and human P. falciparum grown in vitro, aiming to discern the impact of Plasmodium on pipecolic acid production. Previous observations indicated an elevation in pipecolic acid levels correlating with neurological decline in children with CM. In our study, confirming elevated pipecolic acid presence in the plasma and brain tissues of CM patients and the animal model of CM, …
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, …
Group B Streptococcus: Molecular Epidemiology, Pathogenic Profiling And Control Strategies, Katherine Mary Hayes
Group B Streptococcus: Molecular Epidemiology, Pathogenic Profiling And Control Strategies, Katherine Mary Hayes
Theses
Group B Streptococcus (GBS) are frequent colonisers of the gastrointestinal tract of healthy adults with worldwide rates of 18% colonisation; however, they are also opportunistic pathogens capable of causing invasive disease, particularly in neonates and adults with underlying conditions. Indeed, GBS is the leading cause of invasive neonatal disease worldwide with a global incidence of 0.49 per 1000 live births and GBS disease in adults is increasing globally, with estimated rates of 10.9 cases per 100,000 people. While GBS remain largely susceptible to penicillin, there have been reports of reduced beta-lactam susceptibility in certain countries and resistance to other antibiotic …
Crystallographic Studies On Host-Interacting Proteins Of Phage K Virion, Antonio Pichel Beleiro
Crystallographic Studies On Host-Interacting Proteins Of Phage K Virion, Antonio Pichel Beleiro
Theses
Phage K is a lytic bacteriophage that infects a broad range of staphylococci, including some methicillin-resistant Staphylococcus aureus strains. Phage K attaches to its host via a baseplate. The contracted conformation of the baseplate contains a fiber and two receptorbinding proteins responsible for the interaction with the host. The native conformation of the baseplate also includes a tail central spike that shears off after contraction. The aim of the thesis is the structural characterization of phage K receptor-binding proteins and tail central spike. Experimentally, the thesis relies on crystallographic methods, which encompass: production of suitable sample, crystallization, diffraction, and data …

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 …
