Methicillin-Resistant Staphylococcus aureus Biofilms and Their Influence on Bacterial Adhesion and Cohesion

Figure 11

Dispersal of 48 h mature methicillin-resistant Staphylococcus aureus (MRSA) biofilms by DNase and proteinase K. The MRSA isolates are indicated on the -axis; mature biofilms were treated by buffer alone (blue bar) or by consecutive DNase and proteinase K treatment (red bar). Bars represent the mean values ± standard error of the mean of at least three independent experiments. Asterisk () indicates a value of less than 0.05 between the treated group and corresponding control.
