Efficacy of clarithromycin plus vancomycin in mice with implant-related infection caused by biofilm-forming Staphylococcus aureus

摘要

Staphylococcal biofilms pose an important problem, especially after orthopedic surgery using foreign implants. Clarithromycin (CAM) eliminates the biofilms formed by a wide variety of aerobic and anaerobic bacteria. In a previous in vitro study, we showed that treatment with CAM and vancomycin (VCM) eradicated staphylococcal biofilms from surgical implants. To investigate the efficacy of this eradication therapy, we assessed its effects against Staphylococcus aureus on titanium plates implanted in mice.
