Pretreatment of S. epidermidis biofilms with dispersin B renders them sensitive to killing by CPC. (A) S. aureus SH1000 and S. epidermidis NJ9709 biofilms grown in 96-well microtiter plates were treated with 0.3% CPC (for S. aureus) or 0.1% CPC (for S. epidermidis) for 5 min. Values show mean numbers of surviving CFU/well, and error bars indicate range. Black bars show CFU/well values for biofilms pretreated with 20 μg/ml of dispersin B for 10 min prior to addition of the CPC. (B) Time course for CPC killing of S. epidermidis NJ9709 biofilms with or without dispersin B pretreatment. (C) Five-minute killing of S. epidermidis NJ9709 planktonic cells by CPC with or without dispersin B pretreatment.
