Values are expressed as Mean ± S.E.M (n = 3), analysis was performed with One-Way ANOVA followed by Tukey test; ^acompared to positive control, ^bto 19.5 mg/well, ^cto 39 mg/well, ^dto 78 mg/well, ^eto crude 19.5 mg/well, ^fto crude 39 mg/well, ^gto crude 78 mg/well; ¹P < 0.05, ²P < 0.01, ³P < 0.001. The negative control has shown no antibacterial activity * = positive control, Stand = standard (ATCC) strains whereas Clinic = clinically isolated strains, Cip = Ciprofloxacin, --- = no activity
