Antimicrobial susceptibility of Staphylococcus aureus and Staphylococcus epidermidis biofilms isolated from infected total hip arthroplasty cases

Background It is difficult to treat implant-related infections because bacteria form biofilms on implants. Biofilms protect the organisms from the host's immune system and prevent penetration of antimicrobial agents. We investigated the susceptibility of six strains isolated from infected total hip arthroplasty (THA) cases to six antimicrobial agents.
