FIG. 8.

Inhibition of S. epidermidis adherence to immobilized Fg by antibodies. To microtiter plate wells coated with Fg, radiolabeled cells of S. epidermidis which had been preincubated with purified IgG at the indicated concentrations (conc.) were added and allowed to adhere. After the removal of nonadherent bacteria, bound bacteria were quantified by scintillation counting. Mean values from triplicate experiments are shown, with bars indicating standard errors. Symbols: □, IgG against GST-Fbe; ○, IgG against Fbe cleaved from GST-Fbe by thrombin; ◊, IgG against GST; ▵, serum taken before immunization.
