Abstract: Mangifera indica, commonly called mango, is an edible fruit that are also used for juice and wine production. Fresh leaves of M. indica were collected from the premises of Adekunle Ajasin University, Akungba Akoko Ondo State, Nigeria. Materials used, including Gram staining reagents, for the study are properly sterilized. Similarly, the culture media used, including Nutrient agar, MacConkey agar, Eosin methylene blue agar, Salmonella-Shigella agar, Mannitol salt agar, Mueller-Hinton agar and Nutrient broth, were properly sterilized. The bacterial isolates identified and used for the study were Staphylococcus aureus, Salmonella typhi Klebsiella spp., Pseudomonas aeruginosa, Escherichia coli, and Citrobacter spp. Antimicrobial susceptibility test of the Mango (Mangifera indica) leaves extract against the test bacteria shows that 200 mg/ml and 175 mg/ml extract of the plant source had observable effect against test organisms, particularly Escherichia coli, Salmonella typhi, and to a varying extent on others. The zones of inhibition formed at 200 mg/ml were 20 mm, 11 mm, 10.8 mm, 12 mm 16.3 mm and 7 mm for Escherichia coli, Klebsiella spp, Staphylococcus aureus, Citrobacter spp Salmonella typhi and Pseudomonas aeruginosa respectively. Thereafter, the negative control of the 25% DMSO used for dissolving the extract was done and the result was all negative compared with known active positive control – Ampliclox that is an effective antibiotics. With this current observation, Mango, apart from its nutritious component as food complement, coupled with it good fiber contents as fruit, is also found valuable for some antimicrobial purposes. Which means it can be formulated as food supplement or concentrates for some clinical and pharmaceutical purposes.
