Abstract

The existing study was conducted to research the effect of plant extract from flower buds of Dianthus caryophyllus L.by using two different solvents such as Methanol and Ethanol against UTIs hospitals pathogenic bacteria in Iraq, such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and klebsiella pneumoniae. The antibacterial activity was tested against certain hospital harmful bacteria using the agar well diffusion method, with three concentrations (50, 100, 200, and 400 mg/ml) for each extract. Plant extract in ethanol solvent (400 mg/ml) outperformed the antibiotic by a wide margin (P ≤ 0.05) when applied to P. aeruginosa and E. coli pathogenic bacteria, and no effect on S. aureus and K. pneumonia . Finally plant extract in flower buds of Dianthus caryophyllus L. regard a good exporter for controlling hospital pathogenic bacteria.
