Effect of different sequences of ΦK2046 and CHC addition on biofilms from contaminated catheters. A Schematic diagram of the experimental flow; B Killing effect of adding ΦK2046 followed by CHC (90 min interval) on the number of viable bacteria in the biofilm of catheters contaminated with FK2046; P > 0.05 (ns), P < 0.001 (***), P < 0.0001 (****)
