Phage Lysins - Structure, Genetics And Applications, Jennifer Garry
Phage Lysins - Structure, Genetics And Applications, Jennifer Garry
Theses
Antibiotics are of the utmost importance in the fight against pathogenic bacteria, however, in recent years there has been a continual increase in the development of antibiotic resistance among bacteria. As a result it has become essential to develop new technologies to combat these pathogens. One such technology is the application of phage lysins as antimicrobial agents against pathogenic infections. A promising phage lysin is LysK, a 495 amino-acid protein derived from Staphylococcal Phage K. LysK can lyse a wide range of staphylococcal species including MRSA. It is also capable of killing both live and dead cells increasing its potential …
The Rapid Identification Of Novel Anti-Mycobacterial Drugs And The Transporters Involved In Their Resistance, James Carroll
The Rapid Identification Of Novel Anti-Mycobacterial Drugs And The Transporters Involved In Their Resistance, James Carroll
Theses
Despite the success of anti-mycobacterial drugs over the past 70 years, mycobacterial disease, particularly tuberculosis is still responsible for millions of deaths worldwide. Additionally, the emergence of Multidrug Resistant (MDR-TB) and Extensively Drug Resistant (XDR-TB) Tuberculosis throughout the world has motivated calls by the World Health Organization for novel mycobacterial drugs, vaccines and diagnostic tests. Consequently, this study sought to identify and evaluate the efficacy of a range of anti-mycobacterial compounds against a representative cohort of pathogenic mycobacterial species. The development and employment of the rapid, robust and inexpensive microtitre alamarBlue assay (MABA) facilitated the assessment of a vast array …
Isolation And Molecular Characterization Of Mycobacterium Avium Subsp. Paratuberculosis In Ireland, Pierre Emmanuel Douarre
Isolation And Molecular Characterization Of Mycobacterium Avium Subsp. Paratuberculosis In Ireland, Pierre Emmanuel Douarre
Theses
MAP is a proven animal pathogen causing Johne's disease, one of the most widespread and economically important diseases of ruminants. Since 1992 and the opening of the European market, the prevalence of MAP in Ireland has increased considerably. Improvements in diagnostic strategies for Ireland and elsewhere are urgently required. MAP infects a wide host range and has emerged as a potential threat to human health and has been associated with Crohn's disease. The control of paratuberculosis infection requires a better understanding of the genetic diversity of the pathogen. The objective of this study was to isolate and characterize this enteric …
Biosynthesis Of Exopolysaccharides From Lactic Acid Bacteria And Evaluation Of Their Prebiotic Potential, Colette Ann Forde
Biosynthesis Of Exopolysaccharides From Lactic Acid Bacteria And Evaluation Of Their Prebiotic Potential, Colette Ann Forde
Theses
In this study, two strains of lactic acid bacteria (LAB) namely Weissella kimchii F28 and W. confusa MGl were used for the production of exopolysaccharides (EPS) from sucrose. Both strains produced glucan polysaccharides. In the case of W. kimchii F28, the EPS isolation procedure was performed six times, making modifications in order to optimize the yield of EPS. The maximum yield of EPS for this strain was 16 g per litre of culture. In the case of W. confusa MGl, the EPS isolation procedure was followed five times, resulting in a maximum yield of EPS for this strain of 34.4 …
Detection And Molecular Characterisation Of Rotavirus, Adenovirus And Bocavirus Circulating In Southern Ireland, Olivia Cashman
Detection And Molecular Characterisation Of Rotavirus, Adenovirus And Bocavirus Circulating In Southern Ireland, Olivia Cashman
Theses
This study reports the detection and molecular characterisation of group A rotavirus circulating in the south of Ireland in both the bovine and human population. Characterisation of the group A rotavirus was carried out through the extraction of viral nucleic acid in faecal specimens collected from hospitals in the Cork and Waterford area and Cork regional veterinary laboratory from 2006-2009. Other gastroenteritis viruses characterised during this study include adenovirus type 41, and the newly identified gastrointestinal virus, human bocavirus, which was identified for the first time in Ireland during this study. The human bocaviruses identified in children in the south …
Detection And Molecular Characterization Of Canine Enteric Viruses In Southern Ireland., Susan Mcelligott
Detection And Molecular Characterization Of Canine Enteric Viruses In Southern Ireland., Susan Mcelligott
Theses
Enteric viruses, such as canine parvovirus (CPV) and canine coronavirus (CCoV), are a major cause of gastroenteritis in dogs. More serious clinical symptoms occur in young pups, or when both of these viruses infect an animal simultaneously. Caliciviruses and rotaviruses can also cause gastroenteritis in dogs, but these viruses, while causing significant problems in other animal species and humans, are considered to be less significant pathogens of canines. However, on occasion, these viruses have been reported to produce severe clinical symptoms such as vomiting, haemorrhagic enteritis and severe dehydration.
Many viral vaccines for canines are formulated using old vaccine viral …
Identification And Molecular Characterisation Of Mycobacteriophages And Their Lysis Proteins, Marine Henry
Identification And Molecular Characterisation Of Mycobacteriophages And Their Lysis Proteins, Marine Henry
Theses
Given their potential as specific and natural biocontrol agents, bacteriophages and their associated proteins have become the focus of renewed interest over the last decade. This study reviews the current state of mycobacterial diseases control worldwide and presents how phage therapy and the production of recombinant bacteriophage lysis proteins can be applied as novel biocontrol strategies for mycobacteria.
Chapter 11 presents an overview of the predicted LysA and LysB proteins in all the mycobacteriophages sequenced to date and proposes an in silico 3D predictive model of the lysin B of a recently isolated and characterised mycobacteriophage. Our data also confirms …
