Strain-dependent production of the biofilm inhibitory protein.(A) Biofilm formation by strain USA300 FPR 3757 and derivatives. Wells were inoculated with the indicated USA 300 FBR 3757 derivatives. +saePQRSL and +saePQRSP indicate the presence of plasmids pCWSAE50 or pCWSAE51, respectively. (B) Anti-biofilm activity of USA300 derivatives. Culture supernatants from the strains listed to the right of the figure were tested for inhibition of biofilm formation by strain UAMS-1.
