The expression of virulent-associated genes and phenotypic characteristics of S. aureus. a Quantitative RT-PCR analysis showed the genes transcripts in ATCC29213 and MRSA. Experiments were performed in triplicate and presented as the mean ± standard deviation (n = 10; *p < 0.05). b Scanning electron microscopy (SEM) observation of the architecture of S. aureus 24-h biofilms. Clusters of bacterial cells were surrounded by the EPS matrix in MRSA (red arrows). The ATCC29213 cells seemed to be devoid of EPS matrix in the biofilms
