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

Table 1

Quantification of biofilms formed by methicillin-resistant Staphylococcus aureus isolates by microwell plate assay. Biofilms were stained with 0.1% crystal violet solution after 48 h of incubation at 37°C. The values represent mean ± standard error of mean (SEM) for three independent replicates.
