Possible mechanisms by which oral bacteria can cause respiratory infection are as follows: a) Aspiration of oral pathogens into lungs, b) Adhesion and colonization of respiratory pathogens under influence of salivary enzymes, c) Periodontal disease associated enzymes may destroy salivary pellicle on respiratory bacteria, d) Cytokines released during periodontal disease may alter respiratory epithelium and promote respiratory diseases.4
rhamnosus GG, Lactobacillus casei) may affect the oral ecology by specifically preventing the adherence of other bacteria and by modifying the protein composition of the salivary pellicle. Eventually when a species binds well to structures of the oral biofilm, it could be anticipated that this might affect the pathogenic potential of the species based on antimicrobial activity, which infact is another evaluation criterion for probiotics.
visualized the incorporation of CPP into the salivary pellicle with SEM und TEM, with reduction of the adhesion of mutans streptococci [12].
