The regulon of the RNA chaperone CspA and its auto-regulation in Staphylococcus aureus
RNA-binding proteins (RBPs) are essential to finetune gene expression. RBPs containing the coldshock domain are RNA chaperones that have been extensively studied. However, the RNA targets and specific functions for ... -
Relevant role of fibronectin-binding proteins in Staphylococcus aureus biofilm-associated foreign-body infections
Staphylococcus aureus can establish chronic infections on implanted medical devices due to its capacity to form biofilms. Analysis of the factors that assemble cells into a biofilm has revealed the occurrence of strains ... -
RsaI, un ARN régulateur aux multiples facettes, module le métabolisme du pathogène opportuniste Staphylococcus aureus
Staphylococcus aureus est une bactérie commensale retrouvée chez environ 30 % des individus sains dont elle colonise la peau et la muqueuse nasale. Cependant, c’est également une bactérie pathogène opportuniste ... -
Salmonella biofilm development depends on the phosphorylation status of RcsB
The Rcs phosphorelay pathway is a complex signaling pathway involved in the regulation of many cell surface structures in enteric bacteria. In response to environmental stimuli, the sensor histidine kinase (RcsC) ... -
Sensory deprivation in Staphylococcus aureus
Bacteria use two-component systems (TCSs) to sense and respond to environmental changes. The core genome of the major human pathogen Staphylococcus aureus encodes 16 TCSs, one of which (WalRK) is essential. Here we show ... -
Staphylococcus aureus develops an alternative, ica-independent biofilm in the absence of the arlRS two-component system
The biofilm formation capacity of Staphylococcus aureus clinical isolates is considered an important virulence factor for the establishment of chronic infections. Environmental conditions affect the biofilm formation capacity ... -
A super-family of transcriptional activators regulates bacteriophage packaging and lysis in Gram-positive bacteria
The propagation of bacteriophages and other mobile genetic elements requires exploitation of the phage mechanisms involved in virion assembly and DNA packaging. Here, we identified and characterized four different families ... -
Wavelet-based detection of transcriptional activity on a novel Staphylococcus aureus tiling microarray
Background: High-density oligonucleotide microarray is an appropriate technology for genomic analysis, and is particulary useful in the generation of transcriptional maps, ChIP-on-chip studies and re-sequencing of the ...
