Treatment of CMR and CMP with β lactamase (β-LAC) led to a loss of CMR/P antimicrobial potency against S. aureus NCTC6571. CMR (black circle) and CMP (black triangle) were treated with β-LAC to remove penicillin activity (black square and black cross respectively). Statistical comparison of β-LAC treated and untreated CMR and CMP showed a significant reduction in antimicrobial activity following treatment (P ≤ 0.01). All bars show mean values and error bars represent standard deviation, N = 3. Statistical significance was measured by Dunnetts test following two-way ANOVA (**, P < 0.01; ***, P < 0.001).
