ABSTRACT
Urinary tract infections are one of the most common infections worldwide. Given the increasing antibiotic resistance, monitoring antibiotic sensitivity patterns is crucial. Furthermore, silver nanoparticles synthesized from Stachys schtschegleevii can exhibit potent antibacterial, antibiotic, and antifungal properties. The plant S. schtschegleevii was collected from its natural habitat, dried, and its extract was then exposed to silver nitrate. Under specific conditions, silver nanoparticles were synthesized from it. Subsequently, the production and validation of silver nanoparticles were confirmed through techniques such as FTIR analysis, UV-Vis analysis, TEM, SEM, EDX analysis, and zeta potential analysis. In the in vitro section of the research, the impact of the extracted silver nanoparticles on bacteria isolated from patients' urine and standard bacterial culture (control) was assessed using the disc diffusion and MIC test methods. The results of the analyses are FTIR (high protein content; proteins and phenols serve as stabilizing agents), UV-Vis (peak of 460 nm), TEM (spherical to occasionally elliptical shapes), SEM (sizes: 26 to 72 nm), EDX (peak at 3 keV), and zeta potential (- 15.76 ± 0.05 mV). The effect of silver nanoparticles by disc diffusion method (mm) is Enterococcus faecalis = 18.31 ± 0.35, Escherichia coli = 21.51 ± 0.61, and Staphylococcus aureus = 19.02 ± 1.28, and by MIC test (µg/ml), E. faecalis = 19, E. coli = 18, and Staphylococcus aureus = 16. Antibacterial activity of the silver nanoparticles synthesized from S. schtschegleevii means that these herbal nanoparticles treat urinary tract infections caused by some of the test isolates.
