ANTIMICROBIAL SUSCEPTIBILITY OF BACTERIA ISOLATED FROM ORTHOPEDIC IMPLANTS FOLLOWING REVISION HIP-SURGERY

The susceptibilities of 49 isolates recovered from orthopedic implants to seven antimicrobial agents were evaluated by the broth microdiluti on method. Ciprofloxacin and vancomycin were more active than gentamic in, representing aminoglycosides which are routinely incorporated into bone cement, and also more active than the peroperative antimicrobial agents cefamandole and erythromycin. The use of ciprofloxacin and van comycin in vivo, therefore, warrants further evaluation.
