Impact of aureolysin on <i>saeRS</i> and <i>sarA</i>-dependent biofilm formation.

<p>Biofilm formation was assessed in Newman, its P18L derivative, and their <i>sarA</i>, <i>sarA/aur</i> and <i>sarA/ssp</i> mutants with (left) and without (right) the introduction of an intact copy of <i>fnbA</i>. A single asterisk indicates statistical significance (p<0.05) by comparison to the isogenic parent strain, while the double asterisk indicates statistical significance (p<0.05) by comparison to the isogenic <i>sarA</i> mutant.
