Figure 2

Effect of HAM on biofilm susceptibility of S. aureus WT strains, QS mutants and complemented strains.

Biofilms of S. aureus JE2 WT and QS mutants (a) and S. aureus ATCC 49230, ΔtraP mutant and the traP complemented strain ΔtraP pLI50-U1 traP (b) were exposed to VAN alone (black bars) or a combination of HAM and VAN (grey bars). Cell viability was quantified by CTB staining and signals are presented as percentages (average ± s.d.) compared to the signal of an untreated biofilm. *significantly different signals were observed between both treatments (n ≥ 9; one-way; p < 0.01).
