Killing of S. epidermidis cells forming a biofilm on microtiter wells by phage phi-IPLA7 after incubation for 1 h (A) and 3 h (B). Results are depicted as the percentage of attached cells (dark gray square) and planktonic cells (light gray square) detected in control biofilms treated with SM buffer (C) and in biofilms treated with phage phi-IPLA7 (PT). Each value corresponds with the mean of five different experiments and the standard error is represented by bars
