Adhesion of Neisseria meningitidis strains to
extracellular matrix (ECM) and purified matrix components was examined.
Most strains bound to subendothelial ECM as well as to immobilized fibronectin and types I, III, and V collagen. Strains from healthy carriers adhered significantly better than isolates from patients. The
binding site was localized to the central 75-kDa cell-binding domain of
the fibronectin molecule. This domain has not been described previously
to interact with bacterial structures.
