ANTIBACTERIAL EFFECT OF CRATAEGUS PINNATIFIDA EXTRACT AGAINST ENTROCOCCUS FAECALIS A ROOT CANAL DISEASE-CAUSING BACTERIA.

ABSTRACT

Studies have substantiated the anti-inflammatory and anti-thrombotic effects of (C. pinnatifida); however, research on its antibacterial activity using organic solvent remains limited. Therefore, in this study, we aimed to validate the antibacterial activity of C. pinnatifida as a natural extract against Enterococcus faecalis (E. faecalis), a multidrug-resistant bacterium. E. faecalis was treated with different concentrations of C. pinnatifida to determine the optimal concentration for the most effective antibacterial effect. Fifteen different concentrations were applied for 6 and 24 h. The experimental method centered on confirming antibacterial activity using colony-forming units. The experimental results demonstrated a proportional increase in antibacterial activity with elevated C. pinnatifida concentration. Notably, 99.99% and 100% antibacterial activity were observed at 10 mg/mL and 40 mg/mL concentrations, respectively. Our results suggest that C. pinnatifida holds potential as an antibacterial agent against the multidrug-resistant E. faecalis.
