Fig. 1From: Combination antimicrobial therapy: in vitro synergistic effect of anti-staphylococcal drug oxacillin with antimicrobial peptide nisin against Staphylococcus epidermidis clinical isolates and Staphylococcus aureus biofilmsEffect of antimicrobial agents, alone (A, oxacillin and B, nisin) and in combination (C), on biofilm formation in staphylococci studied. The columns represent the average values of triplicate experiments and error bars represent the standard deviations. The asterisks represent the statistical difference between the groups and the control, determined by one-way analysis of variance (ANOVA) followed by Tukey’s honest significant test. Significance was accepted when the P-value was < 0.05 (****P < 0.0001). SA: Staphylococcus aureus, SE: Staphylococcus epidermidis, MIC: Minimum inhibitory concentrationBack to article page
