Rifampin activity against Staphylococcus epidermidis biofilms.
Rifampin has demonstrated remarkable antimicrobial activity against Staphylococcus epidermidis biofilms. Four other antibiotics had no effect when used alone; three of these (clindamycin, gentamicin, and tetracycline) were antagonistic to rifampin when used in combination. Vancomycin was synergistic with rifampin, producing complete killing. Fresh peritoneal dialysis (PD) solution accentuated the antimicrobial activity, whereas spent PD fluid neutralized it.
