Antibacterial activity of the crude methanolic extract of Opuntia monacantha (CM-OM), its fractions nH: n-hexane, Chl: chloroform at 50 mg/mL and the commercially available antibiotic discs LZ: linezolid 30 µg/disk and VAN: vancomycin 30 µg/disk. (a–d) Different strains of methicillin resistant Staphylococcus aureus. The mean zones of inhibition (mm) created by the respective treatments against each bacterial strain were recorded. The data presented are the means of three independent experiments ± SD. *P < 0.05; **P < 0.01, ***P < 0.001 ****P < 0.0001 ns = P > 0.05 (for comparisons of all treatments by one-way ANOVA, followed by Tukey’s Test).
