    The objective of this study was to determine the antibacterial effect of the methanolic extract from the leaves of Nasturtium officinale (watercress) on strains of Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 10536, and Staphylococcus aureus ATCC 25923. Methods: The Kirby-Bauer disk diffusion method was used. To evaluate the antibacterial effect, 72 Mueller Hinton agar plates were used, divided into four groups for different concentrations. Results: The methanolic extract from the leaves of Nasturtium officinale (watercress) showed antibacterial activity against the Pseudomonas aeruginosa ATCC 27853 strain at various concentrations, unlike Escherichia coli ATCC 10536 and Staphylococcus aureus ATCC 25923, which showed no antibacterial effect at any concentration. The greatest antibacterial effect was observed at the concentration of 100 mg/ml compared to the other concentrations. Conclusion: The antibacterial effect of the methanolic extract from the leaves of Nasturtium officinale (watercress) against Pseudomonas aeruginosa ATCC 27853 strains was demonstrated.
