Abstract:
:Porphyromonas gingivalis is one of the major causative agents of adult periodontitis. One of the features of this periodontal pathogen is its ability to attach to a variety of oral bacterial surfaces and to colonize subgingival dental plaque. We have shown that Streptococcus cristatus CC5A inhibits expression of fimA, a gene encoding the major protein subunit of long fimbriae in P. gingivalis; as a result, S. cristatus interrupts formation of P. gingivalis biofilms. Here we further demonstrate that the inhibitory activity of S. cristatus affects multiple strains of P. gingivalis and that optimal inhibitory activity correlates with levels of arginine deiminase expression in S. cristatus. More strikingly, the impact of S. cristatus on P. gingivalis colonization was revealed by comparing levels of P. gingivalis and S. cristatus in subgingival dental plaque. Spearman correlation analysis indicated a negative correlation between the distributions of S. cristatus and P. gingivalis (r = -0.57; P < 0.05). These data suggest that some early colonizers of dental plaque, such as S. cristatus, may be beneficial to the host by antagonizing the colonization and accumulation of periodontal pathogens such as P. gingivalis.
