Probiotic Effect of on Oral Pathogens: An In Vitro Study.

Probiotics, including , have been proposed as an alternative to re-establish the ecology of the oral cavity and inhibit the formation of pathogenic biofilms. The main objective of this work was to assess the probiotic ability of against , , and biofilms. The ability of the strains to form a monospecies biofilm and the probiotic potential of using the competition, exclusion, and displacement strategies were determined. All strains were moderate biofilm producers. The ability of to compete with and exclude and during biofilm formation was not significant. However, significantly reduced pathologic streptococcal biofilms using the displacement strategy. Also reduced the formation of the biofilm mainly through competition and displacement. In vitro, exhibited probiotic potential to reduce the formation of potentially pathogenic biofilms. Further investigation is required to understand the biofilm-inhibiting mechanisms exhibited by this probiotic strain.
