Inhibition Of Listeria Monocytogenes By Human Gut Bacteria, Patrycja Sylvia Olesky
Masters
Listeria monocytogenes is a foodborne pathogen, which continues to be problematic to the food industry due to its ability survive within food products and persist within food processing environments. The growing trend towards natural food preservatives and antimicrobial agents increases the need for the development of novel, natural anti-Listeria agents. Evidence presented in the literature suggests that the human gut microbiota is a reservoir of novel antimicrobial agents. It was therefore hypothesized that novel anti-Listeria agents are produced by human gut-derived bacteria. The objective of this study was to isolate and characterize gut bacteria with anti-Listeria monocytogenes activity. A total …

Due to rapid global urbanization and therefore increased adoption of a 'Westernized' lifestyle, including decreased physical activity and increased consumption of highly processed and refined foods with a high sugar, fat and salt content, prevalence of gastrointestinal disorders are on the rise. Inflammatory bowel disease (IBD) in particular is closely associated with this type of lifestyle. IBD is a term used to describe chronic inflammatory conditions which affects all or parts of the gastrointestinal tract. It includes conditions such as Crohn's Disease, which affects all the gastrointestinal tract and Ulcerative Colitis which mainly affects the colan. Due to the role …
Isolation And Epidemiological Analysis Of Verotoxigenic E. Coli From Patients With Acute Gastroenteritis: A Prospective Study Aiming To Reduce The Burden Of Infection In The Cork Region., Shirley Ross
Masters
Verotoxigenic Escherichia coli (VTEC) is a serious gastrointestinal pathogen associated with morbidity and mortality in the first world, as accentuated by the O104 VTEC outbreak in Germany in 2011. Molecular detection of Verotoxin (VT) has increased the detection of VTEC across Europe however, Ireland still has the highest incidence and isolation is still a key step in the confirmation of infection and the control and prevention of outbreaks. Currently no standard protocol exists for the detection, isolation and characterisation of non-O157 VTEC and it is feared that due to this that the prevalence of VTEC is under-reported. This body of …
