Sensitivity test of some bacteria causing urinary tract infections to local arbutus pavarii extracts

Abstract

: Increased prevalence of antibiotic resistance of urinary tract bacteria this led to negative results for patients, leaving doctors with very few drug options, therefore, it was intended to use plant extracts to solve this problem, so this study was conducted in the laboratories of the Faculty of  Education/ Department of Biology to test the inhibitory efficacy of cold and hot aqueous extracts of the local Arbutus pavarii at concentration (100, 200, 300, 400) mg/ml against some bacteria causing urinary tract infections (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsilla sp., Proteus sp.), by a sensitivity test in form of agar well diffusion method. then compared with Ciprofloxacin.The results showed that extracts of the local arbutus pavarii plant have good inhibitory activity against all tested bacteria, their effectiveness increased with increased concentration, and the hot water extract showed inhibitory activity superior to rest of the extracts and Ciprofloxacin for Pseudomonas aeruginosa at Inhibition diameter (14.7) mm, ethanol extract of 400 mg/ml was superior to aqueous extracts and antibiotics for the most common bacterial species causing these infections E.coli, Klebsilla sp. at inhibition diameter of (8.6) and (11.8) mm respectively, while was antibiotic better than all extracts of Staphylococcus aureus,       Proteus sp., while E.coli were the most resistant to extracts and antibiotics.
