Biofilm forming capacity of <i>S. aureus</i> isolates.

Strains tested are shown along the x-axis and grouped based on methicillin-sensitivity and isolation source. The indicated strains were grown statically for 24 hours. Biofilm formation was quantified by standard microtiter assays and measuring the absorbance at 538 nm, plotted along the y-axis. Bars represent the average absorbance obtained from at least 3 independent plates representing biological replicates. Error bars represent +/- the SEM.
