Inhibition of planktonic (A,B,C) and biofilm (D,E,F) growth by combined savirin and antibiotics (cefazolin, rifampicin, and vancomycin) sub-inhibitory concentrations compared with savirin and antibiotics alone (*** = p < 0.001, ** = p < 0.01, * = p < 0.05). Savirin concentration used in this experiment was sub-inhibitory. Savirin in combination with antibiotics showed enhanced antibacterial and antibiofilm activity against S. aureus compared with savirin alone. Experiments were performed in triplicates (N = 3) and data are presented as mean ± standard deviation (SD) with error bars indicating SD.
