A. bilimbi methanol, chloroform and petroleum ether fruit extracts were tetsed against selected panel of bacteria. Different concentrations of the extract (50mg, 100mg, and 150mg) in each solvent were loaded on 0.4mm sterile discs. The tested gram positive bacteria were more sensitive to the extract when compared to the gram negative bacteria tested. It is well evident that A. bilimbi fruit extract showed applaudable inhibitory activity against the tested pathogens. Further research in this direction is recommended.
