Figure 5.

Evaluation of MRSA ATCC43300 biofilm susceptibility to Sb phage at different time exposures by IMC. Each curve shows the heat produced by viable bacteria present in the biofilm after 24 h (A), 48 h (B), 72 h (C), 120 h (D), 168 h (E), treatment with different phage titers (ranging from 10² to 10⁷ PFU/ml). Graphs on the right represent the magnification of the graphs on the left. Numbers above curves represent Sb titers (in PFU/ml). Circled values represent the MBEC. GC, growth control (dashed line); NC, negative control.
