An effort to make sense of antisense transcription in bacteria
(Taylor & Francis, 2012)
Artículo / Artikulua,
Analysis of bacterial transcriptomes have shown the existence of a genome-wide process of overlapping transcription due to the presence of antisense RNAs, as well as mRNAs that overlapped in their entire length or in some ...
Salmonella biofilm development depends on the phosphorylation status of RcsB
(American Society for Microbiology, 2012)
Artículo / Artikulua,
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) ...
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 ...
Biofilm matrix exoproteins induce a protective immune response against Staphylococcus aureus biofilm infection
(American Society for Microbiology, 2014)
Artículo / Artikulua,
The Staphylococcus aureus biofilm mode of growth is associated with several chronic infections that are very difficult to treat due
to the recalcitrant nature of biofilms to clearance by antimicrobials. Accordingly, there ...
Evaluation of a Salmonella strain lacking the secondary messenger c-di-GMP and RpoS as a live oral vaccine
(Public Library of Science, 2016)
Artículo / Artikulua,
Salmonellosis is one of the most important bacterial zoonotic diseases transmitted through
the consumption of contaminated food, with chicken and pig related products being key reservoirs
of infection. Although numerous ...
Evaluation of surface microtopography engineered by direct laser interference for bacterial anti-biofouling
(2015)
Artículo / Artikulua,
Biofilm formation by bacterial pathogens on the surface of medical and industrial settings is a 25 serious health problem. Modification of the biomaterial surface topography is a promising 26 strategy to prevent bacterial ...
Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or
PNAG (poly-β-1,6-N-acetyl-D-glucosamine). Interestingly, while E. coli and other members
of the family Enterobacteriaceae encode the ...
The regulon of the RNA chaperone CspA and its auto-regulation in Staphylococcus aureus
(Oxford University Press, 2018)
info:eu-repo/semantics/article,
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 ...
A super-family of transcriptional activators regulates bacteriophage packaging and lysis in Gram-positive bacteria
(Oxford University Press, 2013)
info:eu-repo/semantics/article,
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 ...
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 ...
