In Vitro Potency and In Vivo Efficacy of a Novel Bis-Indole Antimicrobial Compound in Reducing Catheter Colonization

ABSTRACT Vascular catheters coated with a novel antimicrobial agent (MBX1631) were studied for their ability to protect against bacterial colonization in vitro and in a rabbit model. MBX1631-coated catheters were significantly less likely to become colonized than control catheters both in vitro and in vivo (P < 0.001). Furthermore, device-associated infection was significantly lower in MBX1631-coated catheters than in uncoated ones (P < 0.005).
