The Effect of Artichoke Ethanolic Extract on Antibiotic-Resistant Clinical Strains of Staphylococcus aureus Isolated from Women

Abstract

Objectives: This study aimed to investigate the inhibitory and lethal effect of artichoke on pathogenic strains of Staphylococcus aureus and compare it with antibiotics in vitro. Methods: Ten strains of S. aureus were isolated from the vagina of women in Amir Al-Momenin Hospital of Zabol, Iran. The resistance pattern was determined by the disk diffusion method. Finally, the effect of the extract on bacteria was determined by the 96-well microplate method. Results: The results of the antibiotic resistance pattern showed that S. aureus samples had the highest resistance to oxacillin antibiotic and were sensitive to other antibiotics, and only one sample was sensitive to vancomycin antibiotic. The lowest inhibitory concentration of artichoke against S. aureus was 3.1 mg/mL, but five strains were inhibited at a concentration of 6.25 mg/mL. Conclusions: Ethanolic extract had a significant inhibitory effect on the growth of S. aureus pathogens. Further clinical research is necessary for clinical use of these extracts.
