Juss (syn. <em>Melia azadirachta</em>) is well known in India and popularly known as Indian neem. To evaluate antibacterial potential, the agar well diffusion assay was used against Gram-negative and Gram-positive bacteria. Penicillin and Dimethyl sulfoxide were used as positive and negative controls, respectively. Methanol extract showed the highest and chloroform extract showed moderate to good antibacterial activity. <em>Proteus vulgaris</em> and <em>Micrococcus luteus</em> were the most susceptible bacteria while <em>Bacillus subtilis</em> was more resistant bacterium to the hexane, chloroform and methanol extracts of neem. The study recommended for the isolation and separation of bioactive compounds responsible for the antibacterial activity.</p> ER -
