Values are expressed as Mean ± SEM (n=3); analysis was performed with One-Way ANOVA followed by Tukey test with Post Hoc multiple comparisons; compared to positive control, to 500mg/ml, to 250mg/ml, to 125mg/ml, and to 62.5mg/ml; 1p<0.0, 2p<0.01, and 3p<0.001. The negative control has shown no antibacterial activity; Chloram = Chloroamphinicole as positive control; SEM = Standard Error of Mean.
