Biomass quantification of MSSA and MRSA. Absorbance (A₅₉₀) of the crystal violet stained biofilm matrix for strong biofilm formers (with A₅₉₀ above the threshold value of 0.374, represented by the horizontal dashed line) at different glucose concentrations. Boxplots at the left show MRSA, in the middle MSSA with MRSA associated MLST CCs and at the right MSSA with MSSA associated MLST CCs. The lower and higher boundary of the box indicates the 25^th and 75^th percentile, respectively. The line within the box marks the median. Whiskers above and below the box indicate the 90^th and 10^th percentiles. Open circles indicate the 95^th and 5^th percentiles. Asterisks denote statistically significant difference, (*) P < 0.05 and (**) P < 0.01.
