We compared the duration of antimicrobial effectiveness of 2 different antimicrobial catheters. The baseline activity of minocycline-rifampin catheters was greater than that of silver-platinum-carbon catheters against Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecalis. The antimicrobial activity of the minocycline-rifampin catheters against these pathogens persisted for up to 12 days, while that of the silver-platinum-carbon catheters was depleted by day 10 (P< .05).
