Average 405 nm light inactivation efficiency following repeated sub-lethal exposure of MSSA and MRSA. 405 nm light inactivation efficiency of 15 sub-lethal exposure cycles of (a) methicillin-sensitive Staphylococcus aureus (MSSA) and (b) methicillin-resistant Staphylococcus aureus (MRSA), to a dose of 108 J/cm2 405 nm light at an irradiance of 60 mW/cm2. Repeated sub-lethal exposure results are reported as bacterial inactivation efficiency (log10 N 0 /N), with N representing the light-exposed population, and N 0 the equivalent non-exposed control population. Each data point is a mean value ± SD (n ≥ 6). No significant changes were observed in the test or final control populations, using one way ANOVA with Dunnett’s post-hoc test (P ≥ 0.05)
