R factor tetracycline and chloramphenicol resistance in Escherichia coli K12 cmlB mutants
(1975)The isolation of Escherichia coli chromosomal mutants that increased the level of resistance of a partially tetracycline-sensitive mutant of RI00-I is described. Plasmid-less derivatives of these moderately resistant mutants ... -
Re-engineering cellular physiology by rewiring high-level global regulatory genes
(2015)Knowledge of global regulatory networks has been exploited to rewire the gene control programmes of the model bacterium Salmonella enterica serovar Typhimurium. The product is an organism with competitive fitness that is ... -
Recombinant vaccines against infectious pancreatic necrosis virus
(Trinity College (Dublin, Ireland). Department of Microbiology, 2000)The rapid expansion of the aquaculture industry in recent years has led to an increase in disease outbreaks. Over the last few years bacterial disease problems have been brought under control, largely due to the use of a ... -
Recombination and complementation between R factors in Escherichia coli K12
(1971)Recombination between chloramphenicol-sensitive (Cms) mutants of Rl, and R100, has been demonstrated in Escherichia coli K12 rec+; it occurs at reduced frequency in recB and recC, and is not detectable in reeA, indicating ... -
Recombination at the coagulase locus in Staphylococcus aureus: plasmid integration and amplification
(1993)The integrating plasmid pCOA18, comprising pUC18 linked to a mutated coagulase (coa) gene from Staphylococcus aureus, and constructed by substituting coa sequences with a tetracycline (Tc)-resistance marker (delta coa::Tcr), ... -
Recombination between Homeologous Chromosomes in Lager Yeasts leads to Loss of Function of the Hybrid GPH1 Gene.
(2009)Yeasts used in the production of lagers contain complex allopolyploid genomes, resulting from the fusion of two different yeast species closely related to Saccharomyces cerevisiae and Saccharomyces bayanus. Recombination ... -
Role for the A domain of unprocessed accumulation-associated protein (Aap) in the attachment phase of the Staphylococcus epidermidis biofilm phenotype
(2014)The polysaccharide intercellular adhesin or the cell wall-anchored accumulation-associated protein (Aap) mediates cellular accumulation during Staphylococcus epidermidis biofilm maturation. Mutation of sortase, which anchors ... -
Role of Staphylococcus aureus coagulase and clumping factor in pathogenesis of experimental endocarditis
(1995)The pathogenic role of staphylococcal coagulase and clumping factor was investigated in the rat model of endocarditis. The coagulase-producing and clumping factor-producing parent strain Staphylococcus aureus Newman and a ... -
Roles for fibrinogen, immunoglobulin and complement in platelet activation promoted by Staphylococcus aureus clumping factor A.
(2005)Staphylococcus aureus is an important cause of infective endocarditis (IE) in patients without a history of prior heart valve damage. The ability to stimulate the activation of resting platelets and their subsequent ... -
The Sbi Protein Is a Multifunctional Immune Evasion Factor of Staphylococcus aureus
(2011)The second immunoglobulin-binding protein (Sbi) of Staphylococcus aureus has two N-terminal domains that bind the Fc region of IgG in a fashion similar to that of protein A and two domains that can bind to the complement ... -
SdrC induces staphylococcal biofilm formation through a homophilic interaction
(2014)Summary The molecular pathogenesis of many Staphylococcus aureus infections involves growth of bacteria as biofilm. In addition to polysaccharide intercellular adhesin (PIA) and extracellular DNA, surface ...
