The Pathogenicity and Transcriptome Analysis of Methicillin-Resistant Staphylococcus aureus in Response to Water Extract of Galla chinensis

Figure 2

G. chinensis extract suppressed biofilm formation and extracellular matrix of S. aureus. (a) Double labeling of S. aureus biofilm. Green, viable S. aureus bacteria (SYTO 9); red, dead S. aureus bacteria (PI); scale bars, 100 μm; (b) double labeling of S. aureus biofilm formation on bone specimens. Green, total S. aureus bacteria (SYTO 9); red EPS (Alexa Fluor 647); scale bars, 100 μm; (c) percentage (%) of viable S. aureus cells in biofilm (n=10, P<0.05); (d) volumetric ratio of the EPS matrix to the bacterial biomass in the biofilms of S. aureus strains (P<0.05, n=10).
