[Fibronectin-binding capacity of staphylococci].

The fibronectin-binding capacity of clinical isolates of the genus Staphylococcus has been studied in the flake-formation test on glass and by inoculation into agar with human fibronectin added. Most of 58 S. aureus strains have been found capable of binding fibronectin. None of coagulase-negative staphylococci has given flake formation with fibronectin. The possibilities of the quantitative evaluation of the fibronectin-binding by the above-mentioned methods have been shown. In the analysis of the monomers of bovine fibronectin its capacity for inducing the growth of compact colonies in semiliquid agar has been shown.
