Introduction: Many natural products possess antibacterial activity which can be used as therapeutic alternative due to the emergence of antimicrobial resistance. Moringa oleifera Lam plant native to the India, use as food, water treatment and traditional medicine. Moringa also has other properties like anti-inflammatory, antimicrobial, antioxidant, anticancer, cardiovascular, hepatoprotective, anti-ulcer, and diuretic activities. Objective: The aim of the present study was to evaluate the antimicrobial activity of alcoholic and aqueous extracts leaf from of three variants of Moringa oleifera (criolla, plain, supergenius) against of the references strains Escherichia coli (ATCC10536), Staphylococcus aureus (ATCC 6538), Candida albicans (ATCC 10231), Pseudomonas aeruginosa (ATCC9027), Salmonella thyphi (9992v), Vibrio cholerae (C7258) and microorganisms isolated from clinical samples. Material and Methods: The antimicrobial activity was determinated for microdilution plating method for determining the Minimum Concentration Lethal (MCL) according the National Committee for Clinical Laboratory Standar (NCCLS). The microorganisms were adjusted with the turbidity standard McFarland 0.5. Two-fold dilutions of the extracts were prepared from concentrations 100 mg/mL until 0.78 mg/mL. Results: The alcoholic extract 70% of criolla variant exhibited the strongest antimicrobial activity against the studied bacterial and yeast strains, with CML 3.1 mg/mL to 5.8 mg/mL. The alcoholic extracts of plain variant showed a weak to moderate activity against the tested microrganisms. The antimicrobial activity of aqueous extracts of the three variants was generally low. Conclusions: Moringa oleifera extracts possess good antimicrobial activity and could be used as source for new therapeutic treatment of infections caused by these infectious agents.
