Box- and whisker plot of the number of viable MRSA isolated from excision wounds treated with photodynamic therapy (PDT). The wounds were inoculated with EMRSA-16 for one hour, treated with PDT using methylene blue and 665 nm laser light (360 J/cm2) and examined immediately after treatment. A 25 fold reduction in the number of viable MRSA was seen in the PDT wounds (L+S+) compared to the controls. Results are presented as box (median, 25th and 75th centiles) and whiskers (minimum and maximum values), n = 12 per group (* indicates p < 0.008).
