Study And Evaluation of the Inhibitory Efficacy of Extracts of Sumbucus Nigra Flower and Tribulus Terrestris Fruits Against The Growth of Bacterial Species Isolated from Patients with Urinary Tract Infection

Abstract

This study was conducted to isolate and diagnose the most important bacterial types causing urinary tract
infection from the inpatients and outpatients to Salah El Din General Hospital using routine isolation and
diagnosis methods. 70 samples were isolated, and the results showed two types of growth: Gram positive
bacteria and Gram negative bacteria, where 10 bacterial types were isolated as follows:
E. coli 42.85%, Kleibsiella. pneumonia 21.42% roteus mirabilis (11.42%), Staphylococcus aureus
(7.14%), Enterobacter cloaca (5.71%), Serratia marcescens (2.85%), Pseudomonas aeruginosa (2.85%),
Staphylococcus Saprophyticus. 2.85%, Micrococcus luteus 1.42%, and Citrobacter freundii 1.42%.
The results of the susceptibility test for 9 types of antibiotics using the discs method showed a change in
the level of resistance to different antibiotics. The most effective antibiotics were Imipenem, Ciprofloxacin
and Sulfamethoxaole. Plant extracts (both aqueous and alcoholic) of Sambucus nigra and Tribulus terrestris
fruits were used, and tested for their ability to inhibit the most isolated bacteria (E. coli , K. pneumonia P.
mirabilis and S. aureus ). All alcoholic extracts were effective in the direction of Bacterial isolates, while
aqueous extracts, have little or no effect.
