Analysis of the inhibition potential of streptococcus salivarius isolated from the saliva and dorsum of the tongue of adults on the growth of streptococcus mutans

Objective: The aim of this study is to analyze the inhibitory potential of Streptococcus salivarius, after it has been isolated from saliva and the tongue’s dorsum, on the growth of Streptococcus mutans. Method: Polymerase chain reaction, SDS PAGE, Bradford test, deferred antagonism test, and well-diffusion test were used. Result: S. salivarius isolated from saliva and the tongue’s dorsum inhibited the growth of S. mutans, but it was not the case with S. salivarius ATCC 13419 (p<0.05). However, there was no significant difference between the inhibition of S. mutans from S. salivarius isolated from saliva and the tongue’s dorsum (p>0.05). Conclusion: S. salivarius isolated from saliva and the tongue’s dorsum can inhibit the growth of S. mutans, but there was no significant difference in the inhibitory potential of S. salivarius isolated from saliva on the tongue’s dorsum.
