RESUMO
Rifampin and trimethoprim were used alone and in combination in the treatment of chronic osteomyelitis due to Staphylococcus aureus in rabbits. Rifampicin levels in infected bone were well above the minimum inhibitory concentration of the infecting strain of S. aureus for at least 4 h after injection. In contrast, trimethoprim levels in diseased bone were below the minimum inhibitory concentration as early as 1 h after injection. Trimethoprim or rifampin, administered alone for 14 days, were ineffective in sterilizing infected rabbit bones. The combination of rifampin plus trimethoprim was significantly more effective (P less than 0.005) than either agents given alone for a comparable duration of time. Staphylococci isolated from the bones of rabbits treated with rifampin alone or rifampin plus trimethoprim were uniformly resistant to rifampin, but retained their susceptibility to trimethoprim.
