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 that produce either a polysaccharide intercellular adhesin/poly-N-acetylglucosamine (PIA/PNAG) exopolysaccharide- or a protein-dependent biofilm. Examination of the influence of...
متن کاملA novel Staphylococcus aureus biofilm phenotype mediated by the fibronectin-binding proteins, FnBPA and FnBPB.
Device-associated infections involving biofilm remain a persistent clinical problem. We recently reported that four methicillin-resistant Staphylococcus aureus (MRSA) strains formed biofilm independently of the icaADBC-encoded exopolysaccharide. Here, we report that MRSA biofilm development was promoted under mildly acidic growth conditions triggered by the addition of glucose to the growth med...
متن کاملFibronectin-binding proteins are required for biofilm formation by community-associated methicillin-resistant Staphylococcus aureus strain LAC.
Community-associated methicillin-resistant Staphylococcus aureus of the USA300 lineage is emerging as an important cause of medical device-related infection. However, few factors required for biofilm accumulation by USA300 strains have been identified, and the processes involved are poorly understood. Here, we identify S. aureus proteins required for the USA300 isolate LAC to form biofilm. A mu...
متن کاملFibronectin binding determinants of the Staphylococcus aureus fibronectin receptor.
Synthetic peptide analogs mimicking a repeated motif within the Staphylococcus aureus fibronectin receptor inhibit binding of the bacteria to fibronectin (Signäs, C., Raucci, G., Jonsson, K., Lindgren, P. E., Anantharamaiah, G. M., Höök, M., and Lindberg, M. (1989) Proc. Natl. Acad. Sci. U.S.A. 86, 699-703). In this study, we have further localized the fibronectin-binding determinant within the...
متن کاملStaphylococcus aureus-fibronectin interactions with and without fibronectin-binding proteins and their role in adhesion and desorption.
Adhesion and residence-time-dependent desorption of two Staphylococcus aureus strains with and without fibronectin (Fn) binding proteins (FnBPs) on Fn-coated glass were compared under flow conditions. To obtain a better understanding of the role of Fn-FnBP binding, the adsorption enthalpies of Fn with staphylococcal cell surfaces were determined using isothermal titration calorimetry (ITC). Int...
