Abstract
Urinary tract infections (UTI) caused by multi-drug resistant (MDR) bacterial pathogens have become a serious global health concern. Main etiological agents for UTI are Escherichia coli, Acinetobacter baumannii, and Pseudomonas aeruginosa. Recently, medicinal plants have found great popularity in medical treatment for different kinds of infections including urinary tract infections. The study has been planned to evaluate the efficacy of alkaloids, flavonoids, saponins and crude extracts of medicinal plants i.e. Syzygium aromaticum, Glycerrhiza glabra,Laurus nobilis and Brassica rapa against MDR urinary tract pathogens through agar well diffusion method. To investigate the Minimum Inhibitory Concentrations (MICs) and Minimum Bactericidal Concentration (MBCs), dilution method was used. Quantitative evaluations of phytochemicals indicated the presence of alkaloids in higher concentrations. Results obtained for the antibacterial activities, the crude extracts of the four plants showed significantly higher inhibition zones as compared to other phytochemicals. The MIC values obtained for different extracts varying from 7.5-15 mg/ml. Comparig the activities of the extracts of the the four medicinal plants it was found that Syzygium aromaticum was the most potent plant against the tested bacterial pathogens indicating its strong candidateship for the drug development.
