Inhibition of the biofilm formation by S. aureus 15981 due to the addition of endolysin LysH5 (0.15 μM) to the culture medium TSBG, and by S. epidermidis F12 due to the addition of the bacteriophage phi-IPLA7 (MOI 100) to TSBG expressed as variation of the CI during biofilm treatment; asterisks show the first incubation time after which two or more consecutive values of CI were statistically different (p<0.05), according to one-way ANOVA tests (S2 Table) (A). Counts (Log CFU/ml) of cells collected, after 24 h of treatment, from the biofilms formed in the E-plates; within each strain, the asterisks (p<0.001) show statistical differences according to ANOVA (B).
