The gamma-hemolysin locus of Staphylococcus aureus comprises three linked genes, two of which are identical to the genes for the F and S components of leukocidin
(1993)The Staphylococcus aureus gamma-hemolysin comprises two polypeptides, whereas the gamma-hemolysin locus (hlg) contains three open reading frames. The hlgA and hlgB genes encode the gamma 1 and gamma 2 components, respectively. ... -
Gene regulation and the Fis nucleoid-associated protein in Salmonella enterica serovar Typhimurium
(Trinity College (Dublin, Ireland). Department of Microbiology, 2005)The Fis protein was found to influence the superhelical density of DNA and its ability to do this differed between Salmonella enterica serovar Typhimurium (S. typhimurium) and Escherichia coli (E. coli). Induction of the ... -
Gene regulation and the leucine-responsive regulatory protein of Salmonella enterica serovar Typhimurium
(Trinity College (Dublin, Ireland). Department of Microbiology, 2007)The leucine-responsive regulatory protein of Escherichia coli (E. coli) is a well characterised global regulator of transcription. Comparatively little is known about the Lrp regulon of Salmonella enterica serovar ... -
Genetic analysis of gentamicin resistance in methicillin- and gentamicin-resistant strains of Staphylococcus aureus isolated in Dublin hospitals.
(American Society for MIcrobiology, 1988)Methicillin- and gentamicin-resistant strains of Staphylococcus aureus isolated in Dublin hospitals have been classified into groups I, II, and III based on resistance to antimicrobial agents and plasmid profiles. Each ... -
Genetic and Molecular Studies of Virulence Factors of Staphylococcus aureus

Genetic diversity of Helicobactor pylori isolates through Microevolution in vivo
(Trinity College (Dublin, Ireland). Department of Microbiology, 2004)Chronic infection with H. pylori causes peptic ulcer disease and its presence is strongly linked with gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. One of the most interesting characteristics ... -
Genetic evidence that bound coagulase of Staphylococcus aureus is not clumping factor
(1992)Staphylococcus aureus Newman cells carry a surface receptor for fibrinogen called clumping factor. The bacteria also express coagulase, an extracellular protein that binds to prothrombin to form a complex with thrombinlike ... -
Genome architecture and global transcriptional control in bacteria: making progress towards a unified model?
(2013)Data obtained with advanced imaging techniques, chromosome conformation capture methods, bioinformatics and molecular genetics, together with insights from polymer physics and mechanobiology, are helping to refine our ... -
Glycomic characterization of respiratory tract tissues of ferrets: Implications for its use in influenza virus infection studies
(2014)The initial recognition between influenza virus and the host cell is mediated by interactions between the viral surface protein hemagglutinin and sialic acid-terminated glycoconjugates on the host cell surface. The sialic ... -
H-NS silences gfp, the Green Fluorescent Protein gene: gfpTCD is a genetically remastered gfp gene with reduced susceptibility to H-NS-mediated transcription silencing and with enhanced translation
(2010)The bacterial nucleoid-associated protein H-NS, which preferentially targets and silences A+T-rich genes, binds the ubiquitous reporter gene gfp and dramatically reduces local transcription. We have redesigned gfp to reduce ... -
H2B ubiquitylation is part of chromatin architecture that marks exon-intron structure in budding yeast
(2011)Background The packaging of DNA into chromatin regulates transcription from initiation through 3' end processing. One aspect of transcription in which chromatin plays a poorly understood role is the co-transcriptional ... -
Helicobacter pylori infection : in vitro diagnostic methods, antimicrobial susceptibility testing, epidemiology of recrudescence and clarithromycin resistance
(Trinity College (Dublin, Ireland). Department of Microbiology, 2000)H. pylori is a Gram-negative, non-spore forming, curved bacterium that colonises the gastric epithelium of the human stomach. H. pylori is firmly established as an aetiological agent in peptic ulcer disease and successful ... -
High-throughput investigation of virulence gene regulation by sRNAs in Salmonella Typhimurium
(Trinity College (Dublin, Ireland). Department of Microbiology, 2015)This study focused on novel gene regulatory systems in Salmonella enterics serovar Typhimurium, a model gram-negative, bacterial pathogen. The sRNA-mediated control of virulence genes was a particular emphasis. The research ... -
The hybrid genomes of Saccharomyces pastorianus-a current perspective
(2018)Saccharomyces pastorianus is a recently evolved interspecies hybrid of Saccharomyces cerevisiae and Saccharomyces eubayanus used in the production of lager-type beers and has a long-standing history with the brewing industry. ...
