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...
Fibronectin-binding proteins of Clostridium perfringens recognize the III1-C fragment of fibronectin
Many pathogenic microorganisms express fibronectin-binding molecules that facilitate their adherence to the extracellular matrix and/or entry into mammalian cells. We have previously described a Borrelia recurrentis gene, cihC that encodes a 40-kDa surface receptor for both, fibronectin and the complement inhibitors C4bp and C1-Inh. We now provide evidence for the expression of a group of highl...
We have determined that virulent Mycoplasma gallisepticum strain Rlow is capable of binding the extracellular matrix protein fibronectin. Fibronectin was found to be present in M. gallisepticum Rlow protein extracts by Western blotting and peptide sequencing. Mycoplasma gallisepticum Rhigh, the attenuated, high-passage derivative of Rlow, is deficient in this ability. MGA_1199, the M. gallisept...
Understanding the role surface proteins play in the interaction of group A streptococci with epithelial cells is an important step toward the development of new strategies to fight infections. Fibronectin-binding proteins in streptococci and staphylococci have been described as important mediators for adherence to eukaryotic cells. In the present study we describe a new Streptococcus pyogenes f...
A novel fibronectin-binding protein from Pasteurella multocida (PM1665) that binds to the fibronectin type III(9-10) modules via two helix-hairpin-helix motifs has recently been described [1]. This protein shares homology with competence-related DNA-binding and uptake proteins (ComEA and ComE) from Gram-positive and Gram-negative bacteria. Here, we show that recombinant PM1665 (now designated C...
Phages directing the synthesis of Treponema pallidum fibronectin binding adhesin proteins, P1 and P2,' were isolated from an EMBL-3 bacteriophage lambda library of T pallidum deoxyribonucleic acid (DNA). The recombinant phages were identified using antisera generated to treponemal proteins purified in fibronectin-Sepharose. Recombinant P1 and P2 proteins possessed the same relative molecular we...
Objective: Alteration in the basement membrane proteins maybe associated with diabetic neuropathy. Fibronectin is one of the most important components of peripheral nerves basement membrane. In this study we investigated the effects of insulin administration on prevention of alteration in fibronectin contents of sciatic nerve in diabetic rats. Materials and Methods: Twenty-four wistar rats wer...
Staphylococcus epidermidis has been reported to bind to a number of host cell extracellular matrix proteins, including fibronectin. Here we report the identification of a fibronectin-binding protein from S. epidermidis. A phage display library of S. epidermidis genomic DNA was constructed and panned against immobilized fibronectin. A number of phagemid clones containing overlapping inserts were...
An objective of this research is to verify the mechanism of anticoagulant activity of surface-immobilized heparin in the presence of plasma proteins. The competition and binding interaction between immobilized heparin and antithrombin III (ATIII)/thrombin have been described in vitro. However, the strong ionic character of heparin leads to its specific and nonspecific binding with many other pl...
