Background and Aim: Enterococci are among the microbial flora in human and animals digestive tract. The nosocomial pathogenicity of enterococci has emerged in recent years. The purpose of the study was to evaluate the effect of a diode laser with a wavelength of 810nm and a power of 30mw at 180s on the survival of an antibiotic resistant enterococci.
Materials and Methods: 30 clinical isolates of enterococcus bacteria were tested for sensitivity to antibiotics according to diffusion method. 10 isolates with the highest antibiotic resistance were selected and diode laser with a wavelength of 810nm and a power of 30mw for 180s were beamed on them and investigated.
Findings: The Results of our antibiotic susceptibility test showed that among 30 isolates resistant to antibiotic enterococci, 27 isolates (90%) were resistant to Oxacillin antibiotics. The results of the diode laser radiation showed that the lowest survival rate of the intended isolates was at 810nm and 30mw for 180s (0.58%).
Conclusion: Based on the results obtained, the antibacterial effect of the diode laser is at 810nm and 30mw for 180s. Therefore, it is recommended to use a 810nm diode laser to eliminate clinical strains of antibiotic-resistant enterococci.
