[A comparative study of the fibronectin-binding capacity of staphylococci]

The comparative study of the fibronectin-binding capacity of S. aureus and S. epidermidis of clinical etiology was carried out. Fibronectin binding was evaluated by original methods: the indirect hemagglutination test and the passive coagglutination test. In this study the occurrence of S. epidermidis isolates, as well as their level (evaluated by the titer) of fibronectin binding, was shown to be lower than those of S. aureus isolates. Fibronectin-binding representatives of S. epidermidis lost this capacity after storage in semiliquid agar at 4 degrees C for 2 months.
