Interaction of Campylobacter jejuni with extracellular matrix components.
The adhesion of three strains of Campylobacter jejuni to coverslips and microwells coated with isolated extracellular matrix components, fibronectin, laminin and types I, III, IV and V collagens was studied. Fibronectin mediated the adherence of C. jejuni, but there were differences in the binding capacities of the strains. Type I, III and V collagens mediated very strongly the attachment of two strains of C. jejuni. All three strains attached weakly to basement membrane-specific type IV collagen. Laminin was capable of mediating the adhesion only when present at a higher concentration. The observations indicate that extracellular matrix components may serve as anchor molecules for C. jejuni adhesion and that several attachment mechanisms occur simultaneously.
