A novel management of streptococcal pharyngotonsillar infections by laser-activated silver nanoparticles and methylene blue conjugate, in vitro study

All the experimental groups showed statistically lower values of CFU/ml than the positive control group. Conclusion: The photoactivated MB, silver nanoparticles conjugate showed the maximum inhibitory effect on Streptococci, which opens a gate to further investigation of such a promising protocol to establish a safe and efficient method of management for resistant cases of streptococcal tonsillar infections.
