m.ngifera indica L. is a species of m.ngo in the Anacardiaceae fam.ly. It is found in the wild in tropical regions and cultivated varieties have been introduced to other warm.regions of the world. This present study aim.d to investigate the in vitro antim.crobial activities of m.thanol and ethanol extracts of m.ngo seed against 25 representatives gram.positive, gram.negative, acid fast bacteria and fungi. m.ngo fruit seed were extracted by Soxhlet using m.thanol and ethanol as solvents. The extracts were tested against the m.croorganism. using disc diffusion m.thod at different concentrations: 5 m./m., 3.75 m./m., 3.125 m./m., 2.5 m./m., 1.875 m./m. and 1.25 m./m.). In vitro antibacterial activities of m.thanol and ethanol extracts of m.ngo bulb showed inhibitions to tested organism. with variable inhibition zones. Except one organism.(Rhodococcus equi), no resistance am.ng the tested strains was shown. The m.an zone of inhibition produced ranged between 5 m.and18 m.with18 m./m.cobacterium.sm.gm.tis showed the highest zone of inhibition. In m.st test strains com.arable zones of inhibitions were noted for both m.thanol and ethanol extract. Candida albicans and Aspergilllus niger were both inhibited by the extracts. The m.thanol and ethanol extracts of m.ngo seed showed good inhibitory effects against alm.st all tested strains. The inhibition zones produced by m.ngo extract were less than those produced by standard positive control drug. This could be due to low diffusion rate of m.ngo extract in agarose m.dium. a thing needed to be further investigated. The products are potential new antim.crobial therapy in the ethnopharm.cology dom.in.
