Objective: This study represents the first attempt to investigate the antimicrobial activity of Peganum harmala , and Trachyspermum ammi seeds extract against the isolated bacillary dysentery -causing microorganisms. Method s: T. ammi and P. harmala were extracted by 96% ethanol using Soxhlet apparatus. The extracts were screened for their phytochemical constituents. Their antimicrobial activity against the isolated dysentery -causing microorganisms was evaluated using the agar diffusion method. Result s: The antimicrobial activity result showed that, the two isolated bacteria, Shigella flexneri , and Shigella dysenteriae were found to be sensitive to the extract of T. ammi seed with inhibition zones up to 2 5 mm , compared to the inhibition zone of 2 0 mm produced by Gentamycin standard drug , this is mainly due to the presence of the different phytochemical in the extract such as tannin, flavonoids, terpenoids whi ch are well known for th eir antimicrobial effects . The two isolated bacteria were found to be insensitive (zero mm) to P. harmala extract, Amoxicillin , and Amoclan (Amoxicillin +clavulanic acid) standard drugs, this is due to the fact that, the phytochemicals constituents of P. harmala possess the antagonistic effect to each other’s . Addition t o; these bacteria became resistant to both Amoxicillin and Amoclan. Conclusio n: From the results it concludes, T. ammi seeds extract had a considerable level of antimicrobial activity against bacillary dysentery - causing microorganisms resistant to Amoxicillin and Amoxicillin +clavulanic acid drugs.
