Abstract
The present study was designed to study the effects of pomegranate, sumac, and Aloe vera extract on Escherichia coli, Staphylococcus aureus, and Citrobacter isolated from urinary tract infection (UTI) in Rizgary teaching hospital-Hawler city. The result of the present study showed that all medicinal plant extracts has inhibitory effects on studied bacteria. The best concentration of pomegranate for inhibition was 50 mg/ml with inhibition zones of 12.200 ± 0.735, 13.200 ± 0.490, and 11.200 ± 0.374 mm for E. coli, S. aureus, and Citrobacter, respectively. While the best concentration of sumac water extract for inhibition was 6% with inhibition zones of 11.400 ± 0.871 and 13.600 ± 0.510 mm for E. coli, S. aureus, respectively, but the best concentration of sumac water extract for inhibition was 4% with zone of inhibition (10.000 ± 0.775 mm) for Citrobacter. Whereas the best concentration of Aloe vera water extract for inhibition was 75% with zone of inhibition of 9.750 ± 0.250, 11.250 ± 0.854, and 11.500 ± 0.289 mm for E. coli, S. aureus, and Citrobacter, respectively.
