OBJECTIVE: To assess whether the antibacterial effect of the aqueous extract of Moringa oleifera (Moringaceae) ““moringa““ on a strain of resistant methicillin Staphylococcus aureus is similar to the effect of oxacillin in vitro. MATERIAL AND METHODS: Experimental study. Double-blind. Preparation of the aqueous extract of Moringa oleifera seed in concentrations of 30 mg / ml, 60 mg / ml, 90 mg / ml, 120 mg / ml under the names BI, BII, BIII and BIV respectively; They were applied on plates inoculated with resistant methicillin Staphylococcus aureus and oxacillin and physiological solution (NaCl 0.9%) were used as positive and negative control, respectively. 12 repetitions were performed for each concentration through the Kirby-Bauer method and its classification according to the Duraffourd Scale that determined the inhibitory effect. The Minimum Inhibitory Concentration (MIC) corresponding to the lowest level of turbidity was also found, it was measured through a spectrophotometer. Statistically, an analysis of variance (ANOVA) and DUNCAN test were carried out on both tests with a significance level of p <0.05. RESULTS: The measurement of the turbidity level to find MIC was as a result 0.027, 0.040, 0.032, 0.024 and 0.024 for BI, BII, BIII, BIV and oxacillin respectively. The averages of the inhibition halos for each concentration are: 17.42 mm for BI; 20.17 mm, BII; 21.00 mm, BIII; 24.92 mm, BIV. ANOVA test shows highly significant difference (p <0.001) between the applied treatments. CONCLUSIONS: The antibacterial effect of the aqueous extract of Moringa oleifera seed evaluated with the formation of inhibition halos was positive on MRSA. There is a significant difference (p <0.05) between the concentrations of the extracts and the positive control (Oxacillin). The minimum inhibitory concentration corresponds to the concentration of 120 mg / ml of the aqueous extract of the Moringa oleifera seed and to the positive control with oxacillin, demonstrating a similar inhibitory effect on the growth of resistant methicillin Staphylococcus aureus.
