Biofilm formation and hydrophobicity of <i>S. pyogenes</i>.

<p>A. Biofilm formation by the various serotypes was determined by the microtiter assay as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0004166#s2" target="_blank">Materials&Methods</a>. Black bars indicate biofilm formation by various serotypes and white bars indicate formation of biofilms in the presence of trypsin. B. Hydrophobicity of <i>S. pyogenes</i>. Black bars indicate the degree of hydrophobicity of the various serotypes as measured by their ability to bind to hexadecane. White bars indicate the percent hydrophobicity after trypsin treatment. All experiments were done in triplicate and performed at least twice. The mean±SD is shown.
