This study was designed to evaluate antimicrobial activity of Allium porrum aqueous extract against some pathogenic bacteria. So that, the aqueous extract of A. porrum was screened for its anti-microbial activity using the plate agar diffusion method. It was tested against six bacterial species; three Gram-positive bacteria (Bacillus subtilis, Streptococcus pneumonia and Staphylococcus aureus) and three Gram-negative bacteria (Escherichia coli, Proteus vulgaris and Pseudomonas aeruginosa). The susceptibility of these different bacterial species toward the extracts of this plant was compared with each other and with selected antibiotics (gentamicin and tetracycline) used as positive control. Results showed that aqueous extract of A.porrum had antimicrobial activity against all bacterial species.Then the active components which exist in aqueous extract were detected. Result indicated that amino acid with sulphate, glycosides, saponin and phenol were present in the aqueous extract.
