Base pairing interaction between 5′- and 3′-UTRs controls icaR mRNA translation in Staphylococcus aureus
(Public Library of Science, 2013)
Artículo / Artikulua,
The presence of regulatory sequences in the 39 untranslated region (39-UTR) of eukaryotic mRNAs controlling RNA stability
and translation efficiency is widely recognized. In contrast, the relevance of 39-UTRs in bacterial ...
RinA controls phage-mediated packaging and transfer of virulence genes in gram-positive bacteria
(Oxford University Press, 2011)
Artículo / Artikulua,
Phage-mediated transfer of microbial genetic elements plays a crucial role in bacterial life style and evolution. In this study, we identify the RinA family of phage-encoded proteins as activators required for transcription ...
Bap, a biofilm matrix protein of Staphylococcus aureus prevents cellular internalization through binding to GP96 host receptor
(Public Library of Science, 2012)
Artículo / Artikulua,
The biofilm matrix, composed of exopolysaccharides, proteins, nucleic acids and lipids, plays a well-known role as a defence
structure, protecting bacteria from the host immune system and antimicrobial therapy. However, ...
Staphylococcus aureus develops an alternative, ica-independent biofilm in the absence of the arlRS two-component system
(American Society for Microbiology, 2005)
info:eu-repo/semantics/article,
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 ...
SarA positively controls Bap-dependent biofilm formation in Staphylococcus aureus
(American Society for Microbiology, 2005)
info:eu-repo/semantics/article,
The biofilm-associated protein Bap is a staphylococcal surface protein involved in biofilm formation. We
investigated the influence of the global regulatory locus sarA on bap expression and Bap-dependent biofilm
formation ...
Beta-lactam antibiotics induce the SOS response and horizontal transfer of virulence factors in Staphylococcus aureus
(American Society for Microbiology, 2006)
info:eu-repo/semantics/article,
Antibiotics that interfere with DNA replication and cell viability activate the SOS response. In Staphylococcus
aureus, the antibiotic-induced SOS response promotes replication and high-frequency horizontal transfer ...
Near-infrared fluorescence imaging as an alternative to bioluminescent bacteria to monitor biomaterial-associated infections
(Elsevier, 2014)
info:eu-repo/semantics/article,
Biomaterial-associated infection is one of the most common complications related with the
implantation of any biomedical device. Several in vivo imaging platforms have emerged as
powerful diagnostic tools to longitudinally ...
Staphylococcal Bap proteins build amyloid scaffold biofilm matrices in response to environmental signals
(Public Library of Science, 2016)
Artículo / Artikulua,
Major components of the biofilm matrix scaffold are proteins that assemble to create a unified structure that maintain bacteria attached to each other and to surfaces. We provide evidence that a surface protein present in ...
Sensory deprivation in Staphylococcus aureus
(Springer Nature, 2018)
info:eu-repo/semantics/article,
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 ...
Killing niche competitors by remote-control bacteriophage induction
(National Academy of Sciences, 2009)
info:eu-repo/semantics/article,
A surprising example of interspecies competition is the production
by certain bacteria of hydrogen peroxide at concentrations that are
lethal for others. A case in point is the displacement of Staphylococcus
aureus by ...
