Abstract: In this study, the antibacterial potential of ethanolic extract combination of three Indian plants Azadirachta indica (A. indica), Garlic (Allium sativum L.) and Psidium guajava were investigated against four microorganisms namely, Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Each combination of ethanolic plant extract was taken in the ratio of 1:1:1, 2:1:1, 1:2:1 and 1:1:2 separately. Disc diffusion method was used to evaluate antibacterial activity. The results indicated that the plant ratio have different degrees of bacterial growth inhibition, depending on the strains and combination of plant extract used.
